(My system info at bottom)

Problem:
The following piece of code doesn't work as advertised:

 while ( $cur = mysql_fetch_row( $result ))
	if ( ! array_search( $cur[0], $userIDs ))
	  {
	    print("Pushing $cur[0]");
	    array_push( $userIDs, $cur[0] );
	  }
	else
	  print( "Ignoring $cur[0]", "/tmp/pushing");

My Solution:
I wrote my own little search method (ignoring Big-Oh consisderations since I don't know PHP low-level types)

function my_array_search( $findMe, $inMe ){
{
  foreach ( $inMe as $key )
    if ( $key == $findMe )
      return true;

  return false;
}


Relevant system info from phpinfo();

Linux myHostName 2.4.18-18.7.xsmp #1 SMP Wed Nov 13 19:01:42 EST 2002 i686

 './configure' '--with-mysql' '--enable-calendar' '--with-apxs=/usr/sbin/apxs' '--with-bz2' '--with-curl' '--enable-track-vars' '--enable-trans-sid' '--with-imap=/usr/local/lib' '--with-imap-ssl=/lib' '--enable-debug'

Cheers.

print( "Ignoring $cur[0]", "/tmp/pushing");
should be
print( "Ignoring $cur[0]" );

storeOutput is my method for sending output debugging to files.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

array_search() returns \"0\" when it finds a match at the first element. Use array_search(...) !== false instead.
