How get PHP fatal errors,warning error, notice error in json response

Question

I am working on a restApi and i am using this api for my mobile and web development.which is build in PHP.i need my error in json format so that i can send this error in a proper response format to android developer and they can also easily handle it.so we will not face any crashing issue in our mobile app.

this is what i need exactly.

PHP ERROR:

Parse error: syntax error, unexpected 'switch' (T_SWITCH) in /var/www/html/phishem/index.php on line 68

What need:

{error_code:"403",message:"Parse error: syntax error, unexpected 'switch' (T_SWITCH) in /var/www/html/phishem/index.php on line 68"}

So how i convert this php error in json response.

yes @TominB i know this. ultimately what i need. i need to send any proper json response to mobile application if any mysql error, php error , or any other error occurs in server side code. — Shakti Sisodiya, Jan 11 '18 at 06:01
but have to do it in every methods. is there any setting in php configuration.that i can get error on a file.like: how log files writes the error. how laravel and other MVC frameworks manage errors. can we do this manually. — Shakti Sisodiya, Jan 11 '18 at 06:07
A parse error means your code cannot compile. Accordingly, it doesn't run. The errors that report an unexpected [PHP keyword](http://php.net/manual/en/language.control-structures.php) usually signals a missing semicolon (`;`) before the reported keyword. Fix the syntax errors. The errors, warnings and notices reported by the PHP interpreter are of no use to the Android front-end. They signal problems in the PHP code. — axiac, Jan 11 '18 at 07:49

In api code you should haldle php warnings and errors, I don't think it is good programinig practice to handle php exceptions and errors in Front end(Android or IOS)

nope we are not handling error mobile side. sometimes we faced the issue that if error in database query or whatever the type of error. obsly mobile application receive a bad json format. that time at least we can send a proper error message so that. we can save our app to crash. – Shakti Sisodiya Jan 11 '18 at 06:00

That kind of error is a Server Side Error, in which must be solve by handling the error instead of giving it as a proper response. Ideally, you must handle/catch all of the possible errors and give a proper response.

OR

You can also develop a service layer (also for a more secured architecture), that will pass through the request and response between the front-end side and the API side. In this case, you can parse a proper response message from the service layer if the server response is 500 which is Internal Server Error and return a JSON formatted message.

You can catch fatal errors and output as JSON like this (in PHP):

function my_error_handler(){
    $error = error_get_last();
    header('Content-Type: application/json');
    echo json_encode($error);
}

register_shutdown_function('my_error_handler');

For non-fatal errors, you need to add this

set_error_handler('my_error_handler');

Additionally, you need to suppress the default error messaging:

error_reporting(0);

These will output the error as the following JSON

{ type : "8", "message" : "Undefined variable: a", "file" : "C:\WWW\index.php", "line" : "2" }
