note 32038 modified in function.eval by danbrown

An example of eval within a function within a class sitting on PEAR DB whose purpose is to push onto a result array named: result_ appended with a parameter key. <?php function set_result_array($fn_request_key = '[DEFAULT]', $fn_result) { $target_array_string = 'result_'.$fn_request_key; // eval ("global \$\$target_array_string;"); eval("\$target_array =& this->\$target_array_string;"); if (!is_array($target_array)) { $target_array = array(); } return array_push($target_array, $fn_result); } ?> What does this illustrate? An example of using eval to create a reference to an object member by reference (=&). The eval ("global ....) line is commented out as I couldn't get this to work for some reason. --was-- An example of eval within a function within a class sitting on PEAR DB whose purpose is to push onto a result array named: result_ appended with a parameter key. function set_result_array($fn_request_key = '[DEFAULT]', $fn_result) { $target_array_string = 'result_'.$fn_request_key; // eval ("global \$\$target_array_string;"); eval("\$target_array =& this->\$target_array_string;"); if (!is_array($target_array)) { $target_array = array(); } return array_push($target_array, $fn_result); } What does this illustrate?
