PHP variables are stored in arrays. This script will parse through one or more arrays, and determine if a variable name (or list of variable names) matches a key or sub-key name. For starters, this lets you determine if HTTP_REFER, REQUEST_URI or other variable is defined before trying to read their values and generating an error. In example: <CODE>$found_vars_list=get_vars_ary($HTTP_SERVER_VARS,'REQUEST_URI'); print_r($found_vars_list); </CODE> <?php if (! defined("__my_func_get_vars")) {define ("__my_func_get_vars", TRUE); function get_vars_ary($vars_ary,$sz_vars='') {if (is_array($sz_vars)){foreach($sz_vars as $sz_v){$v_var_ary=get_vars_ary($vars_ary,$sz_v);if (is_array($v_var_ary)) {$v_ret_ary=(isset($v_ret_ary))?array_merge_recursive($v_ret_ary,$v_var_ary):$v_var_ary;}}}else{if (is_array($vars_ary)){while(list($key, $val) = each($vars_ary)){if (is_array($val)){foreach($val as $v){$v_var_ary=get_vars_ary($v,$sz_vars);if (is_array($v_var_ary)) {$v_ret_ary=(isset($v_ret_ary))?array_merge_recursive($v_ret_ary,$v_var_ary):$v_var_ary;}}}else{if (1>strlen($sz_vars)||(0==strcmp($key,$sz_vars))) {$v_ret_ary=(isset($v_ret_ary))?array_merge_recursive($v_ret_ary,array($key=>$val)):array($key=>$val);}}}}} // if ((isset($v_ret_ary))&&(is_array($v_ret_ary))&&(0<sizeof($v_ret_ary))) {return $v_ret_ary;} if ((isset($v_ret_ary))&&(is_array($v_ret_ary))) {return $v_ret_ary;}}} ?>
