Thank you for the report, and for helping us make PHP better. ------------------------------------------------------------------------ [2006-03-20 23:57:36] judas dot iscariote at gmail dot com although Im not an expert on this, seems the OP example lacks of a valid internal "mysql_link" (created with mysqli_real_connect or similar ) and some validation is missing in the mysqli extension an that result in a crash... I deduce this because using a valid mysqli link the function works as expected. This is a bug anyway, no userspace code should crash PHP. ------------------------------------------------------------------------ [2006-03-20 23:28:15] judas dot iscariote at gmail dot com Program received signal SIGSEGV, Segmentation fault.
