Req #72073 [Com]: Expose encoder_depth to jsonSerialize as parameter

Edit report at https://bugs.php.net/bug.php?id=72073&edit=1 ID: 72073 Comment by: jani dot ollikainen at valve dot fi Reported by: jani dot ollikainen at valve dot fi Summary: Expose encoder_depth to jsonSerialize as parameter Status: Open Type: Feature/Change Request Package: JSON related Operating System: All PHP Version: 5.5.34 Block user comment: N Private report: N New Comment: About the patches: jsonserializedepth is made to PHP7, and jsonserializedepth-55 for PHP5.5. I don't know to which version you would consider including it and if there are differences in versions between, but the patches idea should be pretty obvious. Previous Comments: ------------------------------------------------------------------------ [2016-04-22 08:24:09] jani dot ollikainen at valve dot fi Description: ------------ We have objects that do dynamic loading and there might be recursions. We could use recursion depth to decide when we want to do dynamic loading and when not. Now there doesn't seem to be any way to know how deep is the json_encode process going. If we try to use some level in jsonSerialize it just calls one of those, no recursion there. This could be easily archived by exposing the internal encoder_depth to jsonSerialize. Test script: --------------- <?php class O implements \JsonSerializable { public function jsonSerialize($depth = 0) { if ($depth >= 100) return array(); return array('i' => $this->i, 'o' => $this->o); } } $first = new O; $first->i = 0; $last = $first; for ($i = 1; $i < 500; $i++) { $new = New O; $new->i = $i; $new->o = null; $last->o = $new; $last = $new; } $ret = json_encode($first, 0, 256); var_dump($ret); $a=json_last_error(); var_dump($a); $b=json_last_error_msg(); var_dump($b); Expected result: ---------------- string(1292) "{"i":0,"o":{"i":1,"o":{"i":2,"o":{"i":3,"o":{"i":4,"o":{"i":5,"o":{"i":6,"o":{"i":7,"o":{"i":8,"o":{"i":9,"o":{"i":10,"o":{"i":11,"o":{"i":12,"o":{"i":13,"o":{"i":14,"o":{"i":15,"o":{"i":16,"o":{"i":17,"o":{"i":18,"o":{"i":19,"o":{"i":20,"o":{"i":21,"o":{"i":22,"o":{"i":23,"o":{"i":24,"o":{"i":25,"o":{"i":26,"o":{"i":27,"o":{"i":28,"o":{"i":29,"o":{"i":30,"o":{"i":31,"o":{"i":32,"o":{"i":33,"o":{"i":34,"o":{"i":35,"o":{"i":36,"o":{"i":37,"o":{"i":38,"o":{"i":39,"o":{"i":40,"o":{"i":41,"o":{"i":42,"o":{"i":43,"o":{"i":44,"o":{"i":45,"o":{"i":46,"o":{"i":47,"o":{"i":48,"o":{"i":49,"o":{"i":50,"o":{"i":51,"o":{"i":52,"o":{"i":53,"o":{"i":54,"o":{"i":55,"o":{"i":56,"o":{"i":57,"o":{"i":58,"o":{"i":59,"o":{"i":60,"o":{"i":61,"o":{"i":62,"o":{"i":63,"o":{"i":64,"o":{"i":65,"o":{"i":66,"o":{"i":67,"o":{"i":68,"o":{"i":69,"o":{"i":70,"o":{"i":71,"o":{"i":72,"o":{"i":73,"o":{"i":74,"o":{"i":75,"o":{"i":76,"o":{"i":77,"o":{"i":78,"o":{"i":79,"o":{"i":80,"o":{"i":81,"o":{!
