You can use ltrim()

$sString = '0043680450';
$sString = ltrim($sString,'0');

try casting it to an (int) (if it's a number) and you'll have stripped the 0's (or to a (float)/(double) if it's not an integer)

Hello
How I can get the power of an integer number (for example 8 power 2=64) only
with loops (without pow() function)?
Thanks

Is this for your homework? Untested:

<?php
$num=8;
$power=2;

for ($i=0; $i<$power;$i++) {
   $num*=$num;
}

?>

--- Begin Message --- I wrote a scritpt for testing SOAP-Services. It generates and sends requests to other machines but also receives such requests from other machines in the net.As there are many 'senders' and muc more URL's they are sending their requests to, I intended to write a general SOAP-Request handler, that handles all incoming requests. 

Therefore I Configured Apache 2.0.55 using the ErrorDocument directive:

ErrorDocument 404 /soap/dispatcher.php
Now my tool is able to handle SOAP-Requests to any URL that is located on the Server e.g. (ServerName = spttt.seraph) 

http://spttt.seraph/bli/blo/foo (but also)
http://spttt.seraph/sifdino/services/OrderEntryRequestService

Hope you got the it so far.

Now my problem:
The Soap-Rquest handler needs to read the POST-Data that the sender of the SOAP-Request posted to the script. $HTTP_RAW_POST_DATA should contain this data but also php://input was mentioned in some php-mailing-list messages I found in the archives. My problem is, that my script NEVER gets any POST-Data, if it is called by the ErrorDocument 404 Rule. If I address the handler directly, the Post-Data ist there.
When the script is called by the apache errorDocument handler, the following headers are received: 

HTTP/1.1 404 Not Found

)
Notice the REQUEST_METHOD, which is GET! Obviously the script get's no POST-DATA in a GET-Request... 

- Can anyone tell, if this behaviour is by intention?
- Why are the POST-Data not handed to the ErrorDocument - Script?
- Is there a possibility to solve this (workaround)?
- Im I stupid?

Below further information an my test-scripts:

Hi,

I use OS X tiger which has a PHP v4.3.12 installed.

I would like to be able to generate xml files.

But when I copied a php script from a tutorial and tried it,
Php complaints that
domxml_new_doc is undefined function

How could that be?

Hi:

I am running PHP 4.3.10 (cli) (built: Dec 11 2005 17:38:29) on SuSe 9.3 - and 
am having some problems getting some scripts running.

php was compiled (by Suse) with:
Configure Command =>  './configure' '--prefix=/usr' '--datadir=/usr/share/php' 
'--mandir=/usr/share/man' '--bindir=/usr/bin' '--libdir=/usr/share' 
'--includedir=/usr/include' '--sysconfdir=/etc' '--with-_lib=lib' 
'--with-config-file-path=/etc' '--with-exec-dir=/usr/lib/php/bin' 
'--disable-debug' '--enable-inline-optimization' '--enable-memory-limit' 
'--enable-magic-quotes' '--enable-safe-mode' '--enable-sigchild' 
'--disable-ctype' '--disable-session' '--without-mysql' '--disable-cli' 
'--without-pear' '--with-openssl' '--enable-force-cgi-redirect' 
'--enable-discard-path' '--enable-cli' '--with-pear' 'i586-suse-linux'

(unrelated question - why have --enable-cli and --disable-cli?)

And I have safe mode off in php.ini,
safe_mode = Off

which is verified by a phpinfo();
safe_mode => Off => Off

However, the script should run from a cvs commit (the CVSROOT/logginfo
# BEGIN added by gforge-plugin-cvstracker
ALL ( php -q -d 
include_path=.:/opt/gforge/gforge:/opt/gforge/gforge/www/include:/etc/gforge 
/opt/gforge/gforge/plugins//cvstracker/bin/post.php %r %p %{sVv} )
# END added by gforge-plugin-cvstracker

And in /opt/gforge/gforge/plugins//cvstracker/bin/post.php, the code:
echo "safemode ";
echo ini_get('safe_mode');

Displays : "safemode 1"

I have tried the same thing from the command line, and the only way I can make 
it the same, is to add the "-n" flag.

Any thoughts or pointers?

Thanks
-Robin

Doh - 

I figured it out (for those who were interested). The permissions on 
/etc/php.ini was set to 600 (owner == root). Changing this it other read, fixes 
the issue.

Any idea why Suse would do this?

Thanks

Hi everyone!

I want to connect to an SSL server but i can't get the content :(

Here is the code i use:
$xml = '<xml><data>Hello!</data></xml>';

function PostToHost($host, $path, $referer, $data_to_send) {
  $fp = fsockopen($host, 443);
  printf("Open!\n");
  fputs($fp, "POST $path HTTP/1.1\r\n\r\n");
  fputs($fp, "Host:$host\r\n");
  fputs($fp, "Referer: $referer\r\n");
  fputs($fp, "Content-type: text/xml\r\n");
  fputs($fp, "Content-length: ". strlen($data_to_send) ."\r\n");
  fputs($fp, "Connection: close\r\n");
  //fputs($fp, $data_to_send);
  printf("Sent!\n");
  while(!feof($fp)) {
      $res .= fgets($fp, 128);
  }
  printf("Done!\n");
  fclose($fp);

  return $res;
}

$data = $xml;

printf("Go!\n");
$x = PostToHost(
              "ssl://easy-demo.tcinternet.de",
              "/hosting/servlet/Dispatcher",
              $GLOBALS["HTTP_REFERER"],
              $data
);
echo $x;

And this is what i get:
Go! Open! Sent! Done! HTTP/1.1 400 Bad Request Date: Mon, 09 Jan 2006 10:28:48 GMT Server: Apache/2.0.53 (Unix) mod_ssl/2.0.53 OpenSSL/0.9.7e DAV/2 mod_jk/1.2.1 Content-Length: 363 Connection: close Content-Type: text/html; charset=iso-8859-1 
Bad Request

Your browser sent a request that this server could not understand.
Apache/2.0.53 (Unix) mod_ssl/2.0.53 OpenSSL/0.9.7e DAV/2 mod_jk/1.2.1 Server at easy-demo.tcinternet.de Port 443 

What did the Webserver not understood?

Btw. i can't use cURL because the server has an old version of PHP (><)"
Would be glad if you can help or even have a code how to connect to a SSL webserver via fsockopen that works. 

Btw the PHP version on server is: PHP Version 4.2.2

Thanks for any help!
