In js, I convert a json object into a json string and put it in an implicit input to submit it to php.
This is the HTML part.

The string obtained in php is:

[{\\"table\\":\\"a\\",\\"field\\":\\"value\\",\\"max\\":60,\\"min\\":null}]

String Processing

$ Json_string = $ _ POST ['json'];
$ Json = htmlspecialchars_decode ($ json_string );
Print_r (json_decode ($ json); // The result is null.

Change

$ Json = stripslashes (htmlspecialchars_decode ($ json_string ));
Print_r (json_decode ($ json); // The result is still null.

Change it.

$ Json = stripslashes (htmlspecialchars_decode ($ json_string )));
Print_r (json_decode ($ json); // well, the result is still empty.

It's really hard for you to do so complicated coding.

$s = '[{\\"table\\":\\"a\\",\\"field\\":\\"value\\",\\"max\\":60,\\"min\\":null}]';

$s = html_entity_decode($s);
$s = stripslashes($s);

print_r(json_decode($s, 1));

Array
(
    [0] => Array
        (
            [table] => a
            [field] => value
            [max] => 60
            [min] => 
        )

)

------ Solution --------------------

$str='[{\\"table\\":\\"a\\",\\"field\\":\\"value\\",\\"max\\":60,\\"min\\":null}]';
$new=htmlspecialchars_decode($str);

$new=str_replace('\\','',$new);

$new1=json_decode($new,true);
echo "
";
print_r($new1);
echo "
";

Array
(
[0] => Array
(
[Table] =>
[Field] => value
[Max] => 60
[Min] =>
)

)
------ Solution --------------------
Echo base64_encode ($ _ POST ['json']);
Post result
