Anybody got an idea why $PHP_SELF isn't working with me?
I think because I have set my register_globals to off, but how can I get the
value of $PHP_SELF an another way ?
please try this:
<pre>
<?
/*
Tells whether or not to register the EGPCS (Environment, GET, POST, Cookie,
Server) variables as global variables. You may want to turn this off if you
don't want to clutter your scripts' global scope with user data. This makes
the most sense when coupled with track_vars - in which case you can access
all of the EGPCS variables through the $HTTP_ENV_VARS, $HTTP_GET_VARS,
$HTTP_POST_VARS, $HTTP_COOKIE_VARS, and $HTTP_SERVER_VARS arrays in the
global scope.
*/
var_dump($HTTP_ENV_VARS);
?>
</pre>
<br>
<?
echo $HTTP_ENV_VARS["SCRIPT_NAME"];
?>

Some users in PHP General list may be interested in.
Tom Lane has posted patch for pg_dump to PostgreSQL Admin List.
He said it works with 7.0 (and he said it may work for 6.5 - not tested) This
means
you can backup/restore large object w/o upgrading to 7.1.
Check out the PostgreSQL Admin List if you need it.
(There is news server for the list, too. news://news.postgresql.org )

Hi,
I have a strange kind of a problem. I'm cannot write to files on a server
(i'm having virtual host) where i got my domain name.
The server is running Apache 1.3.x and is having php3.0.8 installed.
The code looks like this:
<html>
<body>
<?php
$fcontents = "something";
$fp = fopen("tmp/some.dat", "w"); // trying to open file in my
directory tmp/ (i think)
fwrite($fp, $fcontents);
fclose($fp);
?>
</body>
</html>
I cannot write to directory tmp.I get an error from Netscape that "document
contains no data" (i changed the directory mode to 777 (tmp/)). The
strangest part is that this script works fine when i am running it at home.
At home i tried to run the script under Windows 98 and Linux Mandrake both
with Apache 1.3.x with php 4.0.x installed (i don't think this code should
have any compatibility problems). On Linux i have put the script to a user
directory, just the kind on the server is, and it worked just fine. I think
maybe it's the Apache configuration (on the server) which is causing my
problem. I would very appreciate any help on this matter (clues what could
be wrong).
Ales!
Hi All,
I need to automatically create a large GIF image made up of numerous smaller
GIF/JPG files.
The list of images (either GIF or JPG) is taken off a MySQL database and at
the moment, I create a HTML table (5 columns, up to 20 rows), view it in my
browser, manually dump it to the screen and then edit it in a image program
to the right size. Then I save it as a transparent GIF and use a server-side
image map to extract the right filename when a user clicks on it. (I'm not
willing to move to a system where each individual image is loaded
individually!)
This is getting a little too time-consuming, so I want PHP to do it for me
;-) I only need it to generate the new images when they are added, so speed
is not an issue. Has anyone created something like this, or does anyone have
any tips on how to do it?
I'm looking into ImageMagick right now (looking through the archives). The
only thing is, I need to do this on my Win98 system..
Thanks in advance,
John

what happens if the webserver once gets started without the php-interpreter
being there? You get to see the raw-files (if they are in the document-root).

Dear Friends,
I am accessing a MySQL database through PHP.
I have to calculate the difference between todays date and the date obtained
from MySQL database.
The Database string is in the form of \"yyyy-mm-dd\".
I have to convert the above string into unix timestamp so that i can calcualte
the difference between the two time stamps.
Please help me in this regard.
Thanking you,
B. Raveendra Reddy

Lots of ways to do it, here's one.
Convert them both to unix timestamps and subtract.
$nowstamp=mktime() ;
$result=mysql_query(SELECT UNIX_TIMESTAMP(mydatefield) AS dbdate FROM
mydatabase);
$row=mysql_fetch_array($result);
$dbdate=$row["dbdate"];
$thedifference=$nowstamp - $dbdate;
//above gives you the difference in seconds.
$daydifference = intval($thedifference / 86400);
// 86400 is number of seconds in a day
// intval because I don't want partial days, just number of days
// $daydifference above gives you the difference in days
kind regards,
bill

well... it was in fact a great idea... but it didn't work... for some
reason... ob_*() functions do not grab warnings and error messages
generated by PHP... so warnings AND the error messages were lost...
maybe I didn't implement it the best way... I don't know... but I really
tried every way I can possibly imagine, and it didn't work.
thanks anyway...

This is what I'd do:
$sql = "SELECT disinct category FROM article ORDER BY category";
$r = mysql_query($sql);
while($cat = mysql_fetch_array($r))
{
$id = $cat['id'];
$sql = "SELECT * FROM article WHERE category='$id'";
$x = mysql_query($sql);
while($row = mysql_fetch_array($x))
{
// echo articles here
}
}
The permanent solution is to make a separate table called "categories" and then
do a join on the categoryID from the two tables.

I want to check if a variable contains a price, like
$19.99
It definitely would be a dollar sign, two integers a dot and
two integers. Here is what I tried which doesn't work.
if (ereg("\$([0-9]{2}).([0-9]{2})", $Price))
or
if (ereg("\$([0-9]{2})\.([0-9]{2})", $Price))
Thanks.

I am not an expert on PHP but I have been programming in Perl for four
years so I can tell you what I would use in Perl and you can see if that
works in PHP. (I am almost sure they would be the same...)
/\$\d\d\.\d\d\.d/
It looks to me like you are forgetting to escape your period making the
interpreter think it is "any character" rather than a literal period. I am
not sure what the {2} is because I have never used that. Does that part of
it really work that way?
Good luck, hope that helps.

Opps. I mistyped that. It should be:
/\$\d\d\.\d\d/
Drop the last d.

<?
$price = "$19.99";
if(ereg("\\$[0-9]{2}\.[0-9]{2}",$price)){
echo "this is a price";
}
else{
echo "not a price";
}
In eregs, if you want to use the $, you have to escape it twice...the
first escape tells php to look for a variable whose name is after the
$...the second \ tells it, look for this character...

Here is my problem.
I have a file, static.php
static.php writes to index.html by way of...
$filename = "/web/h16/docs/index.html";
$fp = fopen("$filename","w");
fwrite($fp, "<table width=\"230\">\n");
etc......
If I hit static.php from the command line, index.html gets written just fine.
static.php does it's job.
If I try to exec(), or system() static.php from a browser the browser just hangs. eg.
I add:
system ('/usr/local/bin/php web/h16/docs/index.html);
or
exec ('/usr/local/bin/php web/h16/docs/index.html);
To a file and get nothing. I tried with and without the absolute paths in the
commands.
What I want to be able to do is every time I update a Db, at the same time I want the
index page to be rewritten to reflect the changes in the Db. And I don't want to have
to go to the command line everytime I want to rewrite the index page. So I would just
hit "SAve" in the update.php page, it would save to the Db, which it does now, and at
the same time it hits static.php and therefore rewrites index.html
I also tried header() but that was no good due to echo in the pages, gives that header
already sent error.
Is there a funtion I am missing somehwere that does the job?
It's a Unix box running php 4.03, and the Db is MySQL
Thanks Much!!

I am still only getting the source of the php file. Has anybody
successfully compiled Apache 1.3.x (1.3.19 in my case) and PHP
(4.0.4pl1) under RH7? My httpd.conf has the proper AddType line and the
php4 module is installed according to httpd -l.
If you have done this successfully, please let me know. I have been
racking my brain for three straight days trying to get this to work.

Somebody knows if it is possible to link C and PHP?
I have a C library and need to 'include' with PHP code, as it does PERL,
is it possible?
Thanks
you can use shared memory functions to ineract between
C and PHP.

I've just finished a proof of concept tutorial about how to create a GTK app
to be your backend on a dynamic PHP site. It steps you through makeing the API,
the GTK app, and the frontend. You can check it out at:
http://gtk.php-coder.net/docs/joe2001_03_31.4.html
For you GTK users it also has a pretty comprehensive example of GtkText(), which
seemed to be lacking.

I posted a message a while ago about having trouble loading php_mssql.dll
extension.
It gave me that error: 'can't find ...'. So I was stuppid enough to realize
I didn't have MS SQL 7 installed here.
Somone here told me to download a proggie called Dependency Walker, that
lists all the dependencies of a DLL.
So I did it, and it really was missing a DLL (MS SQL).
So I installed MS SQL 7 here, and now Dependency Walker doesn't give me any
error, but PHP still gives me the message and still does not load
php_mssql.dll. Why? MSSQL is started, working perfectly, PHP is working fine...
what may be wrong?

I'm sure you appreciate the importance of transitive equality in programming
languages (especially they all aspire to be pseudo-mathematical), which is
why I think you'll appreciate this.
<?php
$a = "0";
$b = 0;
$c = "";
$d = " ";
$a == $b // T
$b == $c // T
$a == $c // F!!
$b == $c // T
$b == $d // T
$c == $d // F!!
?>
Perl, of course, outputs the expected values: $a, $b, $c and $d are equal
under '==', and only $a and $b are equal under 'eq'. PHP's '===' operator
(its equivalent to 'eq') says that $a, $b, $c and $d are all different.
Doesn't that seem like a fundamental flaw? How can equality NOT be
transitive?? How can anyone be expected to write programs in such an
environment?

Hi there,
sometimes I test a new regular expression.
So I've created a test site, which works with
ereg, eregi, preg_match on PHP 4.0.4. Some options
allowed and a benchmarks shows how effective an
expression is.
You're invited to take a look here:

Please send me a private email what do you think about this.
