If all you're trying to do is determine whether the files are different,
and the files are relatively small, then it might be easiest to do
something like:
function filediff($foo, $bar) {
$f_foo = file_get_contents($foo);
$f_bar = file_get_contents($bar);
return ($f_foo == $f_bar);
}
Note that this has the opposite return value of your existing function:
it returns true if the files are THE SAME, like the unix "diff" command.
Alternately, if you want to know what differences exist between files,
you could load the files into arrays with the file() function, then use
the array_diff() function to spit out a list of lines in one file but
not the other.
Or, you could tell us more about what you're actually trying to do. :)

Well, http://www.babysimon.co.uk/khtml2png/ will build a PNG which you could slurp into a PDF using libpdf in PHP. Or, http://marginalhacks.com/Hacks/html2jpg/ may be your solution. Or find it on FreshMeat at http://freshmeat.net/projects/html2jpg/.

I've found that html2ps is way easier to set up than the other two, but the tool is based on standards rather than a browser's idea of what carbon-based lifeforms think is pretty.

Interesting to know. My preg-foo is limited; I came at PHP from a
background of awk and sed, so when I regexp, I'm a little more
traditional about it.
Interestingly, from a shell:
$ text='one two\nthree four\n'
$ printf "$text" | sed -E 's///g'
one two
three four
which is the same behaviour as PHP. But that still doesn't cover
multi-line. PHP's ereg support is supposed to, but doesn't work with
this particular substitution:
$text="one ", "",$text);
returns
one

It's not a matter of escaping. You're matching too much with the ".*".
If you're sure you won't have any right-point-brackets inside comments,
you can use something like:
$text = ereg_replace("","",$text);
Accurately matching comments in an extended regular expression is tricky
though. The only thing you can really *negate* in an ereg is a range,
not an atom. And the close of the comment can't be prepresented as a
range, since it's multiple characters.
Not to say it can't be done. I just can't think of how at the moment.

I never bother with getting the initial record count. Unless you want
to display the total number of available pages, of course (in the vein
of Google search result set).
If all you need is to include "Previous" and "Next" buttons in the right
places, you could simply go with:
$length=40; // or whatever
if ($_GET['offset'])
$offset=$_GET['offset']);
else
$offset=0;
// do the query
$q="SELECT colums FROM table WHERE yadda LIMIT $offset," . 1+$length;
$r=mysql_query($q);
// make Prev/Next links as required
if ($offset > 0)
$prev="";
else
$prev="";
if (mysql_num_rows($r) > $length)
$next="";
else
$next="";
// show the head
print " $prev\n";
print " $next\n";
print "\n";
// show the page
for ($i=0; $i<$length; $i++) {
$row=mysql_fetch_array($r);
print $row['blah']; // wrapped in stuff, of course
}
The idea here is that we always try to SELECT one more entry than we can
display on the page. If mysql_num_rows() sees that many rows, then
there's a page after the current one. And of course, if $offset is > 0
then there's a page before the current one.
I find that this method simplifies my code. I don't need to store the
result of a COUNT() in a session variable, so the "count" remains
valid even if the number of records changes while someone's browsing.
Note that this is not safe code as is. :) At the very least, you
should format-check $_GET['offset'] before using it for anything.

Why not just strip out the braces and explode on commas? That'll be
lighter than regexps any day. If the input is guaranteed to be
formatted the way you describe, you could do something like:
$out = explode(",", substr($in, 1, strlen($in)-2));

I suspect you may not be looking at the problem the right way. What exactly do you want to do? Normally, you'd go the other direction; that is, you'd have mod_rewrite recognize ^/articles/([0-9]+)$ and translate it to /articles.php?id=$1 ... so that a request to the "pretty" URL gets served as an HTTP GET on the PHP script. I get the impression that you're expecting mod_rewrite to translate copy from inside your HTML files, as well as recognize and reverse the translation when the request comes back in.

I've tried > various tweaks and just can't get it to work. I bet if you create an "articles" directory in your documentroot, with with files named things like "999" in it, you'll stop seeing the 404's. Check your apache error_log. If what you're trying to achieve is to have existing HTML files get their embedded URLs translated, you're going to have to do that with an output filter. You can do it with PHP, or use mod_sed ... lots of options. But a rewrite rule won't change page content, it'll only rewrite the *requests* that come in. Of course, if you know all this already, and really are trying to point requests for /articles.php?id=123 to a file named "123" in the directory "articles", then you'll still need to inspect your error_log. -- Paul Chvostek <[EMAIL PROTECTED]> it.canadahttp://www.it.ca/ Free PHP web hosting!http://www.it.ca/web/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: Form woes
Alex,
A switch statement probable isn't the way you want to do this. There is
no real limit to how many of anything should go in a page, but there are
likely better ways to skin this particular cat. Your goal should be to
come up with elegant ways to represent problems, such that large tasks
can be achieved using minimal code.
I'd put your includes in an array. Based on your code, something like:
'create_lsn_name',
2 => 'create_lsn_obj',
3 => 'create_gain',
4 => 'lsn_layout',
5 => 'dev_lsn_page',
);
if ($pages[$_GET['dev']]) {
printf("\n";
} else {
include('create_lsn_name.php');
}
if ($_GET['dev'] < 5) {
$dev=$_GET['dev']+1;
}
?>
Now, adding to the include list is just a matter of updating the array.
Of course, this doesn't address the issue of navigation *backwards*
through the page list.

Re: [PHP] web page thumbs
You're chasing your tail, but it may be possible to catch it. I note that http://www.alexa.com/ has thumbnails of web pages. For quite a while I've wondered how they do that. So I researched. Visit Alexa, find a site with a thumbnail, and download the image. Check out the JPEG comment -- and see the text, "Thumbnail Framer - Mozilla". A search at Google for these words turns up not much at all (framer.sourceforge.net probably isn't what we're looking for), but it got me thinking ... the tools (Mozilla and ImageMagick) are already installed on my workstation, and all I need is glue. So ... here's how I create a web page thumbnail in FreeBSD. First command line option is a URL, the second is an output file. == 8< == #!/bin/sh if [ -z "$2" ]; then echo "Gimme a filename." ; exit 1 elif ! echo "$1" | egrep -q "https?://"; then echo "Gimme a URL." ; exit 1 fi # First, get the page title, so we can identify the window... title="`lynx -source $2 | sed -Ene 's:.*([^<]+):\1:p'`" if [ -z "$title" ]; then title="Mozilla"; fi # Second, launch mozilla... mozilla -width 1024 -height 768 "$2" & # give it a chance to start... make longer if your link is slow. sleep 5 # Third, capture the window via ImageMagick... import -resize '20%' -trim -silent -window "$title" "$2" # Last, kill off mozilla. killall mozilla-bin == 8< == To be safe, I'd run this as its own user. The Mozilla configuration can be set up prior to running so that all extra button bars and windows are disabled or "folded up". There may be more elegant ways of killing off the window, but this is good enough for me. Building a solution that doesn't require a user to be logged in to an X server is left as an exercise for the reader Of course, none of this has anything to do with PHP. p On Wed, Jan 21, 2004 at 11:29:50AM -0600, Alex Hogan wrote: > > Yes..., if that's possible? > > The page in question is for Instructional Developers to select from a series > of templates to develop lessons from.

Beware timestamps, though. They usually won't work for dates before
1970 or after 2038. If you suspect you'll need to use dates outside
that period (for example, show the 90 days of as of some date
in 1969), your results may be unpredictable.
For example, strftime("%+",0) returns "Wed Dec 31 19:00:00 EST 1969" in
my timezone, and strftime("%+",-1) returns a blank. Yet, doing a
strtotime("1969-12-31 23:59:59 GMT") will get you a -1, and the date()
function appears to support negative timestamps ... which means you
can't skimp on your testing if you decide to go this route. ;-)

Validate? How about something like:
eregi('^(f|ht)tp://([a-z0-9._:-]+@)?([a-z0-9][a-z0-9-]+\.)+[a-z][a-z]+(/([a-z0-9.%&=-]+)?)?',$string);
You can adjust the "get" part to suit...

You have a single page, containing multiple forms, all of which share
the same action? What about putting a hidden variable into each form to
provide an authoritative reference to which form was posted? Then, if
processing unique to each form can be done with:
if ($_POST['func']=="thisone") {
// fooblah
} else
if ($_POST['func']=="thatone") {
// barblah
} else
if ($_POST['func']=="another") {
// otherblah
} else {
die("Form hacking detected");
}
And you can do things with the content of $_POST['func'], like this:
$typelist=array(
'thisone' => "This is one",
'thatone' => "That is one too",
'another' => "Another one here",
);
$type=$typelist[$_POST['func']];
Is that long the lines of what you're looking for?

One quick way would be simple subtraction: $old = "1973-06-02"; $new = "2003-08-02"; $year = 60*60*24*365.25; // seconds in a year $age = strtotime($new) - strtotime($old); print "Age in years: " . floor($age / $year) .

I do a little of all three, myself. But, it depends on the project.
If the project is small enough, a single function file will do. I start
to segregate functions by category when I see logical divisions between
the functions. (I.e. billing things, statistical things, etc.) Then I
choose which function libaries to call based on whatever criteria I have
on hand -- usually user input.
Often it's simpler than that -- a project could have a "billing.php"
script that calls "functions-billing.php", and "stats.php" that calls
"functions-stats.php". And if a particular billing function wants to
use something out of stats, it can simply include that library.
Another thing I've done from time to time (though I wouldn't recommend
it) is name your function library after a variable that's used to denote
the part of the program you're running in. For example:
if (ereg('^[a-z]+$',$sect)) @include("functions-" . $sect . ".php");
That way, you're basing your include on something that you're already
managing, perhaps as a form or session variable. YMMV. Don't forget to
do your sanity checking. This method may be prone to security problems.

What user is running the ssh commands? Does that user have a home directory to which it has write permissions in order to create a ~/.ssh/ directory in which to store host keys?

You can't change the Return-Path header, because it's not set by the sender. It's added by the *receiving* mail server, and reflects the from address in the SMTP envelope, rather than anything in the headers of the message itself. It sounds heinous, but one solution might be to make your sendmail_path a *wrapper* that will look at certain environment variables and come up with a -f option with which to launch sendmail. I don't recommend this solution. Another possibility might be to run PHP inside FastCGI and use suexec. If the PHP script is being executed this way, I would think that any sendmail processe launched would have the username in the envelope-from. You also might get a performance gain by doing things through FastCGI, though you'd lose some of the module-specific features like persistent database connections. Worth testing, anyway.

Not so easy with mod_vhost_alias, given that I want it to apply only to certain users, and possibly only for directories for those users. The .htaccess solution is the right one unless "AllowOverride Options" allowed the user to turn off safe_mode and open_basedir. I don't have a non-production machine to test it on at the moment.

Perhaps that's where I need advice. Currently, a .htaccess file with: php_flag register_globals on gets the error "php_flag not allowed here". I see from the comments at http://www.php.net/register_globals that I need AllowOverride Options to make that function ... but is it possible to have fine-grained enough an AllowOverride statement that only register_globals can be changed?

[PHP] How unsafe is register_globals?
I've got this new server running with folks from all over uploading PHP code. I don't know all the folks, so I've turned on safe_mode, set an open_basedir to each user's documentroot, and left register_globals at its default. And now I'm getting scads of requests to turn on register_globals from folks who want to run php-nuke and some other established packages that rely on it. I realize that register_globals isn't itself unsafe ... but do the potential insecurities put my server at risk, or only customer data? By turning register_globals on with an otherwise safe open_basedir, are there things that could be revealed about the server that would otherwise be hidden? My instinct says to leave register_globals OFF, and if folks want to run software that requires it, they should lobby the software maintainers to upgrade the software.

I've got a more flexible way of doing that too. How about this:
$sql = "SELECT * FROM $table_name WHERE ";
if ($_POST['any_all'] == 'ANY') {
$logic = 'OR';
$sql .= '1=0';
}
elseif ($_POST['any_all'] == 'ALL') {
$logic = 'AND';
$sql .= '1=1';
}
else
die ('form hacking detected');
// protect from nasty user input
$string = ereg_replace( '[^a-z0-9]+', ' ', strtolower($_POST['text']) );
$skip = array(
'the' => 1,
'and' => 1,
'a' => 1,
);
foreach (explode(' ', $string) as $val) {
if (!$skip[$val]) {
$sql .= $logic . " name like '%$val%'";
}
}
$sql .= ' ORDER BY name';

What exactly are you hoping to get out of this? What's suposed to be
the eventual content of the $hasSelectedLetter variable? Are these
really how the arrays get set up, or is it really more like:
$booleanNonFormVars = array(
'hasSelectedLetter' => 'somevalue',
'hasEnteredProfile' => 'anothervalue',
...
);
?
If so, you could take advantage of the fact that this is an interpreted
language, and do something like this:
foreach ($booleanNonFormVars as $key => $value) ${$key} = $value;
foreach ($booleanVarsas $key => $value) ${$key} = $value;
foreach ($profileVarArrayas $key => $value) ${$key} = $value;
etc.
Alternately, if $booleanNonFormVars are things for which you're just
trying to test existence, you could:
foreach ($booleanNonFormVars as $value) ${$value} = true;
foreach ($booleanVarsas $value) ${$value} = true;
Is either of these approaches what you're after?

The CREATE TABLE is correct, but look at your ENUM values and DEFAULT.
What kind of quotes are you using? How do you think they should be
interpreted? For easier reading, let's split up the query
$q = 'CREATE TABLE members (userid INT() NOT NULL AUTO_INCREMENT, '
. 'first_name VARCHAR(30) NOT NULL, '
. 'last_name VARCHAR(50) NOT NULL, '
. 'email_address VARCHAR(255) NOT NULL, '
. 'username VARCHAR(30) NOT NULL, '
. 'password VARCHAR(30) NOT NULL, '
. 'activated ENUM("0","1") DEFAULT "0" NOT NULL, '
. 'date_joined DATETIME NULL, '
. 'last_login DATETIME NULL)';
$result = mysql_query($q) or die("Create table Error: ".mysql_error());
It's a heck of alot easier to see errors when you space things out a
bit. The investment of the extra CPU time for PHP to glue the pieces
together probably makes sense in the long run.

What do you mean by "correct"? Why can't you do this in JS? (Note that
even if you do it in JavaScript, you should *still* do it in PHP, to
support all browsers. These days, quite a few corporate networks force
web traffic through proxies that block JavaScript, cookies and sometimes
even Flash.)

It's unfortunate that NotFTP *is* in fact an FTP client, rather than not one. :-/ I really don't want to have to maintain a set of FTP accounts if I can avoid it, but I may look to NotFTP for "inspiration" on a user interface for my own tool. > > Before I write one myself, is there a package that has already been > > built that any one can recommend (or recommend against)? > > I tried this recently, But I discovered that this leaves users directories > rather insecure.

This can be solved neatly by use of open_basedir. Users' scripts can only read files according to limitations that I set on the server. And another option of course is to store all files in blobs in db table. I wouldn't do it for anything high traffic, but for cases where a file will be uploaded once and downloaded once or twice then deleted, I won't have to deal with ongoing performance issues. -- Paul Chvostek <[EMAIL PROTECTED]> it.canadahttp://www.it.ca/ Free PHP web hosting!http://www.it.ca/web/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] safe_mode and file/directory ownership
Jason, safe_mode_gid may indeed be the solution, though it seems to go way too far in relaxing things. It's the functionality of safe_mode that I want ... with the proviso that the web server should be able to read files that it writes. I will not consider turning off safe_mode entirely, any more than I will consider giving customers shell access to my servers. That would seem to be foolhardy. But that may just be the paranoia talking. p On Tue, Jul 01, 2003 at 10:19:01PM -0700, Jason Sheets wrote: > > Take a look at safe_mode_gid, it tells PHP to do safe mode owner > checking using the group id rather than user id. > > safe_mode_gid boolean > > By default, Safe Mode does a UID compare check when opening files.

[PHP] safe_mode and file/directory ownership
I've got a script whose configuration creates a storage directory owned by the web server in which files get stored, also owned by the web server. With safe_mode in effect, I'm getting errors like: Warning: file_exists() [function.file-exists]: SAFE MODE Restriction in effect. The script whose uid is 10054 is not allowed to access /path/to/some/data owned by uid 80 in /path/to/some/file.php on line 111 Wouldn't it make sense for safe_mode also to allow read access to files owned by the web server's process as well as the directory owner's? Obviously, a process running as uid 80 won't be able to suid to another user. If I make the directory owned by the user, the files will be inaccessible, but if I make the directory uid 80, then *it* will be inaccessible. Is there some other solution to storing (and then retrieving) files with safe_mode on?

Try to avoid constant database lookups if you don't really need them. The database server takes alot more resources to find a piece of data than mod_php4 takes to pull it out of a session file. Even data stored in cookies can be moved to session variables for use by the session. If page views then do not require database cycles *or* repeated cookie-based network traffic, you save both CPU and bandwidth. And the session data goes away when the session is destroyed.

I did something similar, not to add headers and footers, but to implement a simple templating system -- the HTML pages had text like __FIRSTNAME__ and __LASTNAME__ which had to be replaced with session variables. The site owner had some very strange ideas about how they wanted to design their site, and wanted to do the whole thing in FrontPage, yet customize pages using data from a PHP-based login. The basic idea is that the customer uploads pages (a few hundred of 'em) all under their DocumentRoot. I've got stuff like: $base="http://www.example.com";; // URL *without* trailing backslash $qu="'" . '"'; $href="( and , as you did with output buffering. I'm not sure if either solution has a performance edge over the other. In both cases, each of the HTML and PHP file get loaded once per page view, and whether the translation happens in PHP's output buffering or via mod_rewrite is probably insignificant.

Don't forget plus signs. When providing email addresses to lists and
web sites, I regularly tag my address (as the From address on this
message demonstrates). Using procmail for local delivery allows these
addresses to be delivered to my account, and I can more easily track
down the origin of "tagged" spam. When I come across a web site or list
that doesn't allow my address with a plus sign, I find another site or
list. So I use:
function isvalidemail($what) {
if
(!eregi('[a-z0-9][a-z0-9._=+-]*@([a-z0-9][a-z0-9-]*\.)+[a-z][a-z]+$',$what))

You probably also want the function to recognize addresses in which the
number precedes the street name (Canada, US, Britain, etc). You also
want to support multiple-word streetnames, which would not work if you
explode using a space as seperator. This is untested:
function splitstreetaddress($what) {
if (ereg('[^0-9][0-9]+$', $what)) {
$temp = ereg_replace('(.*[^0-9])([0-9]+)$','\\1__\\2', $what);
list($name, $number)=explode('__', $temp);
} else if (ereg('^[0-9]+', $what)) {
$temp = ereg_replace('^([0-9]+)(.*)','\\1__\\2', $what);
list($number, $name)=explode('__', $temp);
} else {
$name=$what;
$number=""
}
$retval[0]=trim($name);
$retval[1]=trim($number);
return $retval;
}

Sure, depending on your database. In MySQL, you could use something
like the INSTR() function, making your query something like:
SELECT * FROM table
WHERE INSTR(fullname,'$fname') > 0 OR INSTR(fullname,'$lname') > 0;
or in PostgreSQL, which I believe doesn't have an INSTR function:
SELECT * FROM table
WHERE POSITION('$fname' in fullname) > 0
OR POSITION('$lname' in fullname) > 0;
And to make it case insensitive, wrap the options in LCASE or UCASE.
This sort of thing might be more likely to get a quick response on the
php-db list, and a more concise response if you include the type of
database you're using.

Mind your slashes. Is this PHP script running on a unix/Linux box, or
in MS Windows? If it's unix, remember that a backslash is *not* the
characters used to identify directories.

Remember that from fopen()'s perspective, the root directory is whatever
is root to the web server's process. And a URL's root directory is
the DocumentRoot directive in your Apache configuration. If you have
pointed your DocumentRoot at your operating system's root directory,
then the above setup should work, but otherwise, you need to fopen() the
file relative to your DocumentRoot.
And check your web server's log files. Apache will keep a log of every
HTTP request that's made. That log will always tell you exactly what's
happening, and where the system is looking for files.
> the file permissions are "rw-r-r"
No they're not. They might be "rw-r--r--", but not what you put. When
you talk about file modes, it's safer to refer to them in octal. So
"rw-r--r--" would be 644, and "rw-rw-rw-" would be 666. Less confusion.

[PHP] pro-rated date
Anybody have a quick way of determining the number of days remaining in
the current month?
I'm currently using:
$nextmonth = strftime("%Y-%m-01",strtotime("+1 month"))
$monthdays = strftime("%d",strtotime($nextmonth)-86400);
$daysleft = $monthdays - strftime("%d",time());
I can obviously compact things into a single line, but it's enormous and
offends my sense of esthetics. I was hoping I might be able to feed
something funky like "first day of next month" to strtotime, but the gnu
date input format isn't quite that flexible.
Any advice? Is there an *elegant* way of doing this?

Neat idea. If you've got free SMS and a computer built in to the car already, then why the heck not? I was going to do this once I got my "Empeg Car" unit (ARM CPU and Linux), but never got around to it. If the SMSC is available via IP, then the way to do this in PHP is probably to use an existing SMPP daemon with which PHP communicates using fsockopen(). It should be trivially easy to implement SNPP things and issue AT commands. If you're actually going to have to initiate telephone calls, then you probably want to use PHP only to wrap an existing SNPP client, like Qpage (1), or Hylafax's "sendpage" (2). > Development platform is windows 2000.

Inserting a print_r into your test script tells you the problem, as does
a closer look at http://www.php.net/ksort .
You're assuming ksort()'s return value is the sorted array. It is not.
Try something more along the lines of:
$testarray=array(
"[three]" => 3,
"[two]" => 2,
"[one]" => 1,
);
ksort($testarray);
print_r($testarray);

You can escape the dot either by putting a backslash in front of it or
putting it inside square brackets. So:
ereg("a.b","aaabbb");
is true, but
ereg("a[.]b","aaabbb");
is false. Other "sensitive" characters can also be escaped in this way;
the bracket expression [][.^$()|*+?-] matches any of those characters.
And to match any *except* those characters, use [^][.^$()|*+?-].
Check the re_format(7) man page for details. If you don't have a unix
box handy, check http://www.freebsd.org/cgi/man.cgi?query=re_format .

Are you talking about having a submit button that launches a browser's print dialog, as if the user pressed the print button in their browser, or do you want a user's form submission to cause a printer on (or near) your web server to spit out something based on the form contents? I've build scripts that print to a server-side printer by creating output using pdflib, then submitting the PDF to the local (unix-based) lpr system. Then the only complexity is getting lpr to deal with PDF files (along with solutions to the security issues that surround giving your web server process the ability to submit print jobs). I do this for requests for paper invoices which fit inside window envelopes, so any invoices that turn up on the printer just get stuffed and mailed. I also do something similar for requests for FAXed quotes. The software builds a PDF, then submits it to Hylefax's sendfax program, which dumps it to a fax server elsewhere on the network.

[PHP] PHP vs Perl for system scripts (non-web)
I have to write a swath of code to manage system-related stuff based on database content. Scripts will be run as root by cron, and determine what they have to do via user interaction and SQL lookups. Functions will include manipulation of system configuration files, legacy text file configs, and some signalling with posix_kill. On some of the machines in question, there won't even be an httpd installed, so I'd be building a php as a standalone binary, and running it with shell magic and a -q option. I've done this kind of stuff in the past in smaller environments, and it seems to work nicely. I'm more comfortable writing stuff in PHP. I use PHP alot more, and I find the resultant code more readable and easier to maintain. Aside from Perl's ubiquity and the dubious advantage of future flexibility by using Perl's DBI interface to talk to different SQL servers (I'm using MySQL at the moment), are there any compelling reasons I should write system stuff in Perl rather than PHP?

[PHP] creating random strings?
I need to create batches of randomly generated usernames and passwords. To start off, I have: $validuchars='abcdefghijkmnopqrstuvwxyz'; $validpchars='abcdefghijkmnopqrstuvwxyz23456789'; $lenu=strlen($validuchars)-1; $lenp=strlen($validpchars)-1; The first method I came up with was: $uid=''; for($i=8;$i;$i--) $uid.=substr($validchars,mt_rand(0,$lenu),1); $pwd=''; for($i=8;$i;$i--) $pwd.=substr($validchars,mt_rand(0,$lenp),1); But I'm wondering if there's any significant benefit to this instead: for( $uid=''; strlen($uid)<8; $uid.=substr($validuchars,mt_rand(0,$lenu),1) ); for( $pwd=''; strlen($pwd)<8; $pwd.=substr($validpchars,mt_rand(0,$lenp),1) ); I can't see any difference in speed. Does the savings of the $i variable have any signficance at all? Another thing I was thinking of doing was making more pronouncable usernames with something like: $cons="bcdfghjklmnpqrstvwxyz"; $vowels="aeiouy"; $lenv=strlen($vowels)-1; $lenc=strlen($cons)-1; $uid=""; for($i=4;$i;$i--) $uid.=substr($cons,mt_rand(0,$lenc),1) . substr($vowels,mt_rand(0,$lenv),1); Any thoughts? Incidentally, I'm guaranteeing uniqueness of usernames with a unique index in the MySQL table that stores this stuff. Including the INSERT, I can create about 10 of these in 60 seconds.

This isn't really a PHP question, since ping is a command in the OS and
not in PHP itself. And of course, you didn't mention what OS you run.
I run FreeBSD. In FreeBSD, ping has options that could be used thusly:
$target="209.238.46.67";
exec("/sbin/ping -c 1 -t 3 $target", $junk, $ret);
if ($ret==0)// In shell, 0 means success
print "Wahoo! I can see $ipaddr!\n";
else
print "Bummer... $ipaddr seems to be down.\n";
The option -c specifies a "count" (the number of pings to send), and -t
specifies a timeout in seconds. If your operating system is UNIX or
Linux, you can "man ping" from a shell to see what you need to do to
duplicate this functionality, or check out various OS man pages at
http://www.freebsd.org/docs.html#man . If you're running a Microsoft
operating system, you're most likely out of luck.

[PHP] Re: Multidimensional arrays (more and more...)
Well, counting is easy... count($issue) will be correct. If you want
to count things that match only specific elements, use things like:
$c=0;
foreach($issue as $what)
if ( $year==2003 && $month>=5 )
$c++;
As I said in the previous email, to sort by array elements, you'd need
to use array_multisort. Something like...
$sortkey=array();
foreach($issue as $what)
$sortkey[]=$what['number'];
array_multisort($issue,$sortkey);
And for looping, foreach is still your best bet:
foreach($issue as $key => $what) {
if ($what['senttosubscribers']==0)
$issue[$key]['description'].=" (EMPTY)";
else
$issue[$key]['description'].=str_replace(" (EMPTY)","",$what['description']);
}
With regard to PHP being "screwey", I haven't found this -- I use
multidimensional arrays quite a bit and find that they behave exactly as
I would predict. Maybe I'm just lucky. ;-)

A multidimensional array is just an array whose values are themselves arrays. So ... $thing="2002-11"; // or whatever $issue=array(); $issue[$thing]=array(); $issue[$thing]['number']="this"; $issue[$thing]['headline']="that"; And if you ksort($issue), the key/value associations will be maintained; you're just changing the order of the elements.

[PHP] Re: Hello ! How to write a programme in PHP which executes a routine at a given time ?
PHP itself does not have any facility for running things according to a schedule in the way you describe. It looks like you need to run some additional software using cron (or your operating system's equivalent). Unix systems have a command called "at" which can be used to execute things at specific times, but what it actually executes is still a problem. If you want to be able to launch programs on external machines, there are security issues which must be addressed as well. And what does "centian" mean?

You could always see if it matches a regular expression that represents
the ascii range you're considering. I.e., ereg('[^a-zA-Z0-9]',$string)
will return true if non-alphanumerics are in the string.
Remember that a string is just a string. Whether the data contained in
it is represented as ASCII or something else is completely a matter of
implementation. ALL 7-bit data can be represented as ASCII. All 8-bit
data can be represented as "IBM Extended ASCII" or whatever you want to
call it. But the string is just a string of bits.
