I have some regex patterns stored as strings inside a PHP array. I need them to be outputted as JavaScript RegExp objects. Is there any way to do this by using PHP's json_encode?
Example:
$array = [
'regex' => '/some-regex/'
];
return json_encode( $array );
Desired output:
{"regex": /some-regex/}
Current output:
{"regex": "/some-regex/"}
分享 No, you can't. Because you're passing through JSON structure which just wraps-data. A string by json standard starts with " and ends with ", otherwise it's a number or an array for istance.
I wondered a similiar thing about it. I wanted to create a function for JS but on server side with php, based on the result. Usually when you face this problem it means you've to rethink a bit the structure of your page/app.
However as they pointed out in the comments to your question, you might find workarounds to build the object locally once the HTTP request is ended.
