Operating system: Linux RH 7.3
PHP version:      4.3.0RC3
PHP Bug Type:     Arrays related
Bug description:  array_search skips element 0

(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;
}
