If you need the JsonSerializable Interface in PHP<5.4... this could help:
<?php
$fallback_jsonencode = !interface_exists("JsonSerializable", false);
if($fallback_jsonencode){
interface JsonSerializable{
public function jsonSerialize();
}
function fallback_json_encode($obj){
if(is_numeric($obj)){
return $obj;
} else if(is_string($obj)){
return "\\"".$obj."\\"";
} else if(is_bool($obj)){
return $obj?"true":"false";
} else if(is_array($obj)){
$parts = array();
$keys = array();
//$assocarr = false;
foreach($obj AS $k => $v){
$parts[$k] = fallback_json_encode($v);
//if(!is_numeric($k)) $assocarr = true;
}
/*if($assocarr){
$out = ""; $sep = "\\"";
foreach($parts AS $k => $v){
$out .= $sep.$k."\\":".$v;
$sep = ",\\"";
}
return "{".$out."}";
} else {*/
return "[".implode(",",$parts)."]";
//}
} else if(is_object($obj)) {
if($obj instanceof JsonSerializable) $obj = $obj->jsonSerialize();
$parts = array();
foreach($obj AS $k => $v){
$parts[] = "\\"".$k."\\":".fallback_json_encode($v);
}
return "{".implode(",",$parts)."}";
} else return "null";
}
}
?>
Note: This Code runs slightly faster than the PHP 5.4 Implementation on my machine, but it DOES NOT
SUPPORT ASSOCIATIVE ARRAYS like that. Just uncomment the commented section for that and it should
work.
