Description:
------------
Trying to set up a FPM status page using this one:
http://git.php.net/?p=php-src.git;a=blob;f=sapi/fpm/status.html.in;h=86492d73df0710d5dd0a0550292b3b48bbbfc302;hb=HEAD

I got "Error while parsing json: 'SyntaxError: JSON.parse: bad escaped character':

{
    "pool": "www",
    "process manager": "dynamic",
    "start time": 1364474757,
    "start since": 623,
    "accepted conn": 1998,
    "listen queue": 0,
    "max listen queue": 0,
    "listen queue len": 0,
    "idle processes": 135,
    "active processes": 2,
    "total processes": 137,
    "max active processes": 9,
    "max children reached": 0,
    "processes": [{
            "pid": 32124,
            "state": "Idle",
            "start time": 1364474757,
            "start since": 623,
            "requests": 15,
            "request duration": 2262,
            "request method": "GET",
            "request uri": "/hidden/timthumb.php?src=http://hidden.fr/wp-content/uploads/2012/10/vitrolles-640x426.jpg&q=100&w=220&h=160&text=Pas+d\'image+pour+le+moment", <<< Here is the bug?
            "content length": 0,
            "user": "-",
            "script": "/hidden/timthumb.php",
            "last request cpu": 0.00,
            "last request memory": 1310720
        }, OTHER....]
}

Sound like the JSON output of the status using "?json" in the query string is badly escaped?

Expected result:
----------------
Good parsing.

Actual result:
--------------
Parse error.

as the html says, "This is sample real-time status page for FPM. You can change it 
to better feet your needs."

maybe you need escape the backslash in request uri by yourself

Hi, could you explain what is the element "last request cpu": 0.00 unit. i have the data with the last request cpu:234, means use the cpu 234%?

#66119 seems to be a duplicate but with a clearer description.

Because the output of status?json isn't properly encoded all kinds of status monitoring tools break when encountering unescaped characters.

laruence@php.net Here is a blogpost regarding this issue; https://thomasp.vivaldi.net/2021/04/01/a-noisy-check/. The author of the post initially tried to work this out by encoding as well, but to no avail. And whichever piece of code that encodes to JSON -where-ever it may be- should -imo- be responsible for for properly encoding the contents.
