note 92817 added to function.json-encode

Note that this function does not always produce legal JSON. <?php $json = json_encode('foo'); var_dump($json); //string(5) ""foo"" $json = json_encode(23); var_dump($json); //string(2) "23" ?> According to the JSON spec, only objects and arrays can be represented; the JSON_FORCE_OBJECT flag available since PHP 5.3 does not change this behaviour. If you're using this to produce JSON that will be exchanged with other systems, adjust your output accordingly. <?php $json = preg_replace('/^([^[{].*)$/', '[$1]', $json); ?> The json_decode function accepts these JSON fragments without complaint. ---- Server IP: 66.207.199.35 Probable Submitter: 70.74.192.79 ---- Manual Page -- http://www.php.net/manual/en/function.json-encode.php Edit -- https://master.php.net/note/edit/92817 Del: integrated -- https://master.php.net/note/delete/92817/integrated Del: useless -- https://master.php.net/note/delete/92817/useless Del: bad code -- https://master.php.net/note/delete/92817/bad+code Del: spam -- https://master.php.net/note/delete/92817/spam Del: non-english -- https://master.php.net/note/delete/92817/non-english Del: in docs -- https://master.php.net/note/delete/92817/in+docs Del: other reasons-- https://master.php.net/note/delete/92817 Reject -- https://master.php.net/note/reject/92817 Search -- https://master.php.net/manage/user-notes.php
