It collects values from the search results, and pushes them on to an array to return. This code works great for smaller query results, but it causes a segmentation fault with larger numbers (approximately 1300 results) Running PHP 4.2.2 Apache 1.3.6 (mod_frontpage, mod_rewrite) MySQL 3.23.43 --- EXAMPLE CODE --- $mailDbLink = mysql_connect($mailserver,$mailuser,$mailpass) or die("Could not connect to mail system"); mysql_select_db($maildbname) or die("Could not select appropriate database in 98-11 system"); $query = mysql_query($processEmailTableSql) or die("Could not perform 98-11 search: " . mysql_error()); while($row = mysql_fetch_array($query)) { array_push($resultsArray,$row["MessageID"]); } return $resultsArray; ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=18743&edit=1
