PHP：json_encode将斜杠改为\ /

Question

I have a variable which contains a path in json_encode /users/crazy_bash/online/test/

but json_encode converts the path to this:

 \/users\/crazy_bash\/online\/test\/

Why? How can i display a normal path?

the code

$pl2 = json_encode(array(
    'comment' => $nmp3,
    'file' => $pmp3
));
echo($pl2);

It's perfectly legal JSON, see http://json.org/. \/ is converted to / when unserializing the string. Why worry about it if the output is unserialized by a proper JSON parser?

If you insist on having \/ in your output, you can use str_replace():

// $data contains: {"url":"http:\/\/example.com\/"}
$data = str_replace("\\/", "/", $data);
echo $data; // {"url":"http://example.com/"}

Note that it's still valid JSON by the definition of a string:

_{(source: json.org)}
