Hi Reader's,
 Welcome to FindNerd, today we are going to discuss use of json_encode() function in php.

json_encode() is used to convert the array given as it's argument into a JSON string. JSON full form is JavaScript Object Notation.

If you are using json_encode() function then always json_encode() function returns a function when json_encode() function function will work.

json_encode() function returns a JSON encoded string on success or returns FALSE on failure.

Syntax of json_encode() function

you can see below example:

<?php

//First you need a PHP array of data
$result = array(
    'first_name'    =>    "Tom",
    'last_name'    =>    "Gray",
    'phone_number'    =>  123456789,
    'address'    =>    "USA"

);
//here call json_encode() function
$jsondata = json_encode($result);
//print json_encode data
print_r($jsondata);

?>

Output will come following of above example

{"first_name":"Tom","last_name":"Gray","phone_number":123456789,"address":"USA"}
