How to convert the PHP Array to JSON String

Hi, In this tutorial, I am going to explain, How to convert the PHP Array to JSON String.

If you want to convert the PHP Array to JSON String use the json_encode().It will convert the PHP Array to JSON String.

Syntax: json_encode($array, Constant1 | Constant2 .... | Constantn);

Consider sample PHP Array

$array = array(
"website" => "TechNoise",
"url" => "http://technoise.info",
"description" => "Programming Blog"
);

Now we have to convert this array to JSON string.

<?php  
 $array = array(  
 "website" => "TechNoise",  
 "url" => "http://technoise.in",  
 "description" => "Programming Blog"  
 );  
 //json_encode($array);  
 $JSON=json_encode($array, JSON_PRETTY_PRINT | JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES);  
 echo "<pre>";  
 echo $JSON;  
 echo "</pre>";  
 ?> 

Output

{
    "website": "technoise",
    "url": "http://technoise.in",
    "description": "Programming Blog"
}
