note 100789 added to function.array-key-exists

I created this function that uses array key exist to compare a form and a table to see if something has changed. This can be very helpfull if you need to update a table record from a form but you do not want to display all table fields. function($data_from_db, $form_data) { $data = $data_from_db; $keys = array_keys($data); for($i = 0; $i < count($data); $i++) { if(!array_key_exists($keys[$i], $form_data)) { $dbobject->$keys[$i] = $data[$keys[$i]]; } else { $dbobject->$keys[$i] = $form_data[$keys[$i]]; } } return $dbobject; } you can then use the dbobject to update the table. ---- Server IP: 69.147.83.197 Probable Submitter: 86.82.170.144 ---- Manual Page -- http://www.php.net/manual/en/function.array-key-exists.php Edit -- https://master.php.net/note/edit/100789 Del: integrated -- https://master.php.net/note/delete/100789/integrated Del: useless -- https://master.php.net/note/delete/100789/useless Del: bad code -- https://master.php.net/note/delete/100789/bad+code Del: spam -- https://master.php.net/note/delete/100789/spam Del: non-english -- https://master.php.net/note/delete/100789/non-english Del: in docs -- https://master.php.net/note/delete/100789/in+docs Del: other reasons-- https://master.php.net/note/delete/100789 Reject -- https://master.php.net/note/reject/100789 Search -- https://master.php.net/manage/user-notes.php
