Ok - This is a reply to ALL - Thanks for the great help - I now understand
why it wasn't displaying - it was all due to caching of data at the client
end before displaying in blocks. With some help in the comments of the php
manual for flush() I found a nice script that uses echo str_pad('',1024); to
help pad things out - also displays a little countdown to keep people amused
and convinced something is happening while the service restarts! I'm LOVING
php now - its a very simple language limited only by your imagination as to
how you use it! My knowledge seems to be lacking more in HTML and Browser
server relationships - I'm basing things on my background in Basic
programming as a kid - you do Print "Hello world" and it does that instantly
to the screen - little different with browsers!

It's a little different with network communication.
Try programming something for the console using the CLI
(Command-Line Interface) version of PHP, should be much less
confusing.

Take this with a grain of salt. I develop with PHP, but I am not an

the filename isn't in a variable.
Compiled when execution hits them. You can prove this by trying to
conditionally include a file with a syntax error: if (false)
include('script_with_syntax_error.php'); won't cause an error.
Secondly, are include files that are referenced, but not used, loaded
into memory? I.e Are statically included files automatically loaded
into memory at the start of a request? (Of course those where the name
is variable can only be loaded once the name has been determined.) And
when are they loaded into memory? When the instruction pointer hits
the include? Or when the script is initially loaded?
If your include file is actually included, it will use memory. If it is
not included because of some condition, then it won't use memory.
Are included files ever unloaded? For instance if I had 3 include
files and no loops, once execution had passed from the first include
file to the second, the engine might be able to unload the first file.
Or at least the code, if not the data.
If you define a global variable in an included file and don't unset it
anywhere, then it isn't automatically "unloaded", nor are function/class
definitions unloaded when execution is finished.
Once you include a file, it isn't unloaded later though - even included
files that have just executed statements (no definitions saved for
later) seem to eat a little memory once, but it's so minimal that you
wouldn't run into problems unless you were including many thousand
files. Including the same file again doesn't eat further memory. I
assume the eaten memory is for something to do with compilation or
caching in the ZE.
Thirdly, I understand that when a request arrives, the script it
requests is compiled before execution. Now suppose a second request
arrives for the same script, from a different requester, am I right in
assuming that the uncompiled form is loaded? I.e the script is
tokenized for each request, and the compiled version is not loaded
unless you have engine level caching installed - e.g. MMCache or Zend
Optimiser.
I think that's correct. If you don't have an opcode cache, the script is
compiled again for every request, regardless of who requests it.
IMO, you're probably better off with PECL/APC or eAccelerator rather
than MMCache or Zend Optimizer. I use APC personally, and find it
exceptional -> rock solid + fast. (eAccelerator had a slight performance
edge for my app up until APC's most recent release, where APC now has a
significant edge.)
Fourthly, am I right in understanding that scripts do NOT share
memory, even for the portions that are simply instructions? That is,
when the second request arrives, the script is loaded again in full.
(As opposed to each request sharing the executed/compiled code, but
holding data separately.)
Yep, I think that's also correct.
Fifthly, if a script takes 4MB, given point 4, does the webserver
demand 8MB if it is simultaneously servicing 2 requests?
Yep. More usually with webserver/PHP overhead.
Lastly, are there differences in these behaviors for PHP4 and PHP5?
Significant differences between 4 and 5, but with regards to the above,
I think they're more or less the same.

Unless you're using an opcode cache, as I believe some of the are smarter
about that. Which and how, I don't know. :-)

I don't know for sure but chances are that mysql outputs errors on
stderr not stdout, so you need to redirect stderr to stdout for exec to
capture it...
exec("mysql -h hhh -u uuu -pppp < test.php 2>&1",$out,$bin);

Can't say why you're not getting an error message, but when I have a valid
user, password, host, and sql in a .txt file, I get the last record from the
select statement I run output in the browser. Maybe start with getting it to
work with everything used correctly, then work backwards.

The 2>&1 syntax redirects stderr to stdout, it does not do anything with
stdout. So yes, you will still also get stdout messages.
This no longer has anything to do with PHP. I suggest you Google for
info on Linux pipes.

I am creating a form right now. I am using the html SELECT tag.
<SELECT NAME="day_of_month">
The most number of days in a month is 31
I want the output to be <OPTION SELECTED>## based on the value of
$selected_day_of_month variable. For the days of the month where the
number is not selected the output I am desiring is
<OPTION>1
<OPTION>2
etc.
to be generated through PHP code
I already have a value the user submitted in a variable named
$selected_day_of_month from being stored in a mySQL table
Does anyone know how to do this in a few commands? I am wanting to
simplify
<?
if ( $selected_day_of_month == "1" ) }
<OPTION SELECTED>1
} ELSE {
<OPTION>1
}
if ( $selected_day_of_month == "2" ) }
<OPTION SELECTED>2

Dang that's painful!! Try this...
<?php
foreach (range(1, 31) as $day)
{
print '<option value="'.$day.'"';
if ($selected_day_of_month == $day)
print ' selected';
print '>'.$day.'</option>';
}

I added a value to the options (you knew that was missing right?).
Obviously you need to output the <select ...> and </select> outside this
loop.

...and if you wanted to go an extra step you could try an alternate
syntax of the exact same code:
<?php
foreach (range(1, 31) as $day)
print '<option value="' . $day . '"' . ($selected_day_of_month
== $day ? ' selected' : '') . '>' . $day . '</option>';
?>
Either way, Stut is correct. Don't type this out 31 times unless you
really really really like to type. ;-)

Ouch! Gnarly mix of logic and markup. I suggest something more like:
foreach (range(1, 31) as $day)
{
$sSelected = ($selected_day_of_month == $day) ? '
selected="selected"' : '';
print <<< hdDay
<option value="$day"$sSelected>$day</option>
hdDay;

Ewww, I'll take Stut's style anyday. Heredoc has its uses, but I
wouldn't consider your above usage one of them :/ Now to add my own
flavour...
<?php
for( $day = 1; $day <= 31; $day++ )
{
$selected
= $selected_day_of_month == $day
? ' selected="selected"'
: '';
echo '<option value="'.$day.'"'.$selected.'>'
.$day
.'</option>';
}
?>
Cheers,
Rob.

What you want is something like this:
foreach ($languages as $language => $valueArray ){
if ( strstr( $_HTTP_ACCEPT_LANGUAGE, $language) ) {
print"<center>You are from ".$valueArray[2]."!</center>";
}
}
Your example is setting the variable $language to the array for each
iteration.
Thanks, I see what I was missing.
So the first iteration,
$language is set to array("Afrikaans", "Afrikaans", "South Africa")
and the second iteration,
$language is set to array("Albanian", "Shqipe", "Albania")
That much I knew. Thanks, Chris.

Why not just do
if(isset($language[$_HTTP_ACCEPT_LANGUAGE])) {
print '<center>You are from
'.$language[$_HTTP_ACCEPT_LANGUAGE][3].'!</center>';
} else {
print '<center>where are you from?!</center>';
}
using strstr is pretty slow, and considering you made the indices
correspond to the actual value you're checking em for... this is a lot
faster ^^ (and cleaner IMO)

ofcourse, that should've read:
$languages = array(
"af" => array("Afrikaans", "Afrikaans", "South Africa"),
"sq" => array("Albanian", "Shqipe", "Albania") );
if(isset($languages[$_HTTP_ACCEPT_LANGUAGE])) {
print '<center>You are from
'.$language[$_HTTP_ACCEPT_LANGUAGE][3].'!</center>';
} else {
print '<center>where are you from?!</center>';

Well since the consensus seemed to be to allow job postings, I'll make
one. :-)
My company is looking for a few good PHP programmers.
We are a Chicago-area web consulting firm developing web sites and web
applications for a variety of clients, including several large academic
institutions. We are looking for skilled PHP developers to join our team.
(Sorry, that means yes, you'd have to work with me.) It's a small but
growing company of less than 10 people, all fairly young and geeky. :-)
Experience with PHP (although not necessarily prior work experience) is a
must.
If interested, contact me OFF-LIST for more information. Note: I am NOT in a
hiring position, so do NOT send me your resume. :-) I'm just going to pass
you on to the person who is.

Rob, I'd love to know what aspect of my heredoc usage you find
objectionable. From my perspective it's a single integrated
expression, cleaner, easier to read and proofread, and easier to
maintain than a concatenation of expression fragments strung together
with syntactical punctuation and quotation marks. I especially value
the fact that heredoc lets me separate program logic from text output
to the greatest extent possible. Am I unwittingly committing a
stylistic or logical faux pas?
Conversely, what applications of heredoc do you find valid and valuable?
I ask because I use heredoc all the time, sometimes for inline code
as above but most often for template assembly, maintaining HTML in
external files that can be edited independently of the PHP logic.
Curiously,
Paul

Now this is obviously just opinion since everyone is entitled to their
own style, and while I might find it objectionable, I hardly represent
the masses and their idiosyncrasies :)
Now, the thing that I dislike about heredoc for such small strings is
the switching between heredoc mode and the switching back. It's ugly on
the scale of switching in and out of PHP tags. it would be less ugly if
the closing delimiter didn't have to be at the beginning of it's own
line in which case code could still maintain indentation formatting.
Understandably it is not like this since it's flexibility lies in being
able to place very versatile content within while not accidentally
breaking out of heredoc context. To lighten the mess of heredoc I
personally use the following format:
<?php
$foo = <<<_
<div class="$foo" id="wooohooo">
blah blah blah blah blah blah blah blah blah blah
blah blah $foo blah blah blah blah blah blah blah
blah blah blah blah blah blah $fee blah blah blah
blah blah blah blah blah blah blah blah blah blah
</div>
_;
?>
However that's only useful if indenting the content is not an issue.

My example also illustrates the kind of content I would be willing to
contain within a heredoc... namely a large chunk of content, most likely
with a mix of double quotes and variables. That said, I'm still more
likely not to use heredoc... I think the one exception where I'm quite
likely to use heredoc is when I'm declaring a javascript function from
within a PHP function.

I use a tag based template system, there's no PHP in my content so my
content files for the most part just look like more HTML. The templates
are compiled to PHP (or raw content such as when creating stylesheets)
after which they are used over and over without recompiling. here's an
example of an email template:
--------------------------------
Hello <jinn:render name="email" selector="firstName"/>,
You or somebody posing as you has requested that your password
be reset. If you did not request this email then you may disregard
it and no changes will be made to your account.
To continue please click on the link below and complete the form
that will be presented. If clicking on the link does not open
your browser then please copy and paste the address into a web
browser to continue.
http://<jinn:render name="email"
selector="domain"/>/reset.php?rid=<jinn:render name="email"
selector="serialCode"/>
Sincerely,
Admin
--------------------------------
Here's the code that invokes the template:
<?php
$mail = &$this->getServiceRef( 'mail' );
$mail->addTo( $to );
$mail->setSubject( 'BlahBlah.com - Reset Password Request' );
$mail->setTemplate( '//emails/passwordResetDetails.php', $data );
$mail->send();
?>
Cheers,
Rob.

It's so interesting that some details bug some people and others bug
others. In an expression such as this:
echo '<option value="' . $day . '"' . $selected . '>' . $day
. '</option>';
...I count eight transitions (instances of switching between PHP
syntax and output text) -- one each time you open or close a quote --
compared to just two transitions (the opening & closing labels) for
the comparable heredoc statement:
print <<< hdDay
<option value="$day"$sSelected>$day</option>
hdDay;
it would be less ugly if
the closing delimiter didn't have to be at the beginning of it's own
line in which case code could still maintain indentation formatting.
I agree. Too bad the PHP developers didn't come up with a special
symbol for heredoc closing labels to give us more control over script
formatting. I do however find this a fairly minor irritation, a
small price to pay for heredoc's power.
To lighten the mess of heredoc I
personally use the following format:
$foo = <<<_
...
_;
Nice and concise! Thanks, I'll use that.
However that's only useful if indenting the content is not an issue.
I don't see how you draw that conclusion. Heredoc doesn't become
useless if we need to indent the content, it just means we lose
complete control over indenting every line of our PHP script. The
functionality is still totally there.
This script indenting issue with heredoc is for me one of the few
irritations of PHP. I love the language and the power that heredoc
gives me. I'm also irritated by the class member syntax $this->that
but I still use it as well.

I use a tag based template system, there's no PHP in my content so my
content files for the most part just look like more HTML.
This is a different topic, but also one close to my heart. Yes, I
too use my own selector-based templating system. It does allow me to
embed PHP variables into the template if I want, but the primary
merge between plain HTML template and MySQL content happens through
CSS-style selectors.
Hello <jinn:render name="email" selector="firstName"/>,
Cool.
My comparable example (but in an HTML context) would look like:
Hello <span class="firstName">FIRSTNAME</span>,
where the engine replaces the content of the span with the value from
the database based on a match of 'span.firstName' or perhaps just
'.firstName'. (In this example the 'FIRSTNAME' content in the
template is merely a place-holder to make it easier to preview the
markup and isn't necessary to the merge process.)
