Hi, How would I go about determining if a specific key exists in an array? I want to see if $conf['hOpt'] is defined. is_array only works at the $conf level.You want: if(isset($conf['hOpt'])) { ... } You should always use isset to check if a variable is set, whether it is a straight variable, an array index, or an object member. -- paperCrane <Justin Patrin>
