note 104784 added to function.json-encode

The JSON_NUMERIC_CHECK flag introduced in 5.3.0 comes in very handy when handling numbers encapsulated in a string (database results and post requests are always encoded as string types, for example). Sending over variables from a database result directly (as string) would cause the json_encode() function to quote them, which in turn would make the Javascript store them as strings. As Javascript isn't loosely typed, some libraries could break on this, when attempting to use one of those variables as row id in a data store for instance. Using the aforementioned flag can prevent this from happening. <?php $arr = array( 'row_id' => '1', 'name' => 'George' ); // fictional db result echo json_encode( $arr, JSON_NUMERIC_CHECK ); // {"row_id":1,"name":"George"} ?> ---- Server IP: 83.137.20.135 Probable Submitter: 82.93.68.91 ---- Manual Page -- http://www.php.net/manual/en/function.json-encode.php Edit -- https://master.php.net/note/edit/104784 Del: integrated -- https://master.php.net/note/delete/104784/integrated Del: useless -- https://master.php.net/note/delete/104784/useless Del: bad code -- https://master.php.net/note/delete/104784/bad+code Del: spam -- https://master.php.net/note/delete/104784/spam Del: non-english -- https://master.php.net/note/delete/104784/non-english Del: in docs -- https://master.php.net/note/delete/104784/in+docs Del: other reasons-- https://master.php.net/note/delete/104784 Reject -- https://master.php.net/note/reject/104784 Search -- https://master.php.net/manage/user-notes.php
