PHP JSON String, escape Double Quotes for JS output
Another way would be to encode the quotes using htmlspecialchars:
$json_array = array( 'title' => 'Example string\'s with "special" characters');$json_decode = htmlspecialchars(json_encode($json_array), ENT_QUOTES, 'UTF-8');
I succefully just did this :
$json = str_replace("\u0022","\\\\\"",json_encode( $phpArray,JSON_HEX_QUOT)); json_encode() by default will escape " to \" . But it's still wrong JSON for json.PARSE(). So by adding option JSON_HEX_QUOT, json_encode() will replace " with \u0022. json.PARSE() still will not like \u0022. So then we need to replace \u0022 with \\". The \\\\\" is escaped \\".
NOTE : you can add option JSON_HEX_APOS to replace single quote with unicode HEX value if you have javascript single quote issue.
ex: json_encode( $phpArray, JSON_HEX_APOS|JSON_HEX_QUOT ));
Use json_encode($json_array, JSON_HEX_QUOT);since php 5.3: http://php.net/manual/en/json.constants.php
