In this article we will show you the solution of convert array to JSON PHP, to achieve the result we need an array with multiple set of values for this topic, so we created associate type array.

In this array usually it holds various column values with respective values. To happen the conversion you need json_encode() method.

The json_encode() allows you to do the conversion of PHP data into JSON format. It takes php object and gives JSON string as output of result.

Step By Step Guide On Convert Array To JSON PHP :-

Create array variable as per your wish, to hold defining set of arrays and values. Three columns namely, (Age, Department, Work Experience) and two row arrays created.

You can change array values with set of information as like you want without fail and columns also not mandatory.

All you need to pay attention is define everything or modify in the correct format.

Finally using echo() method, you have to pass array variable to json_encode() method result will you get correctly.

<?php
$arr_data = array(
"Dhanu" => array("Age"=>25,"Department"=>"Writer","Work Experience (In Years)"=>2),
"Prawin" => array("Age"=>26,"Department"=>"Mechanic Engineer","Work Experience (In Years)"=>4),
"Arun" => array("Age"=>24,"Department"=>"Director","Work Experience (In Years)"=>1)
);
echo json_encode($arr_data);
?>

1. A php script can be placed anywhere in the document. A php script starts with <?php and end with ?>.
2. The default file extension for php files is “.php” and php statements end with ‘;’ semicolon. In php we need to specify ‘$’ symbol before the variable name also default rule.
3. First, we created variable $arr_data, here you can change this variable name as per your wish but keep in mind pre-defined rules for variable definition.

5. In the line, the block of code can changeable but try to modify in a right manner to get error-free result.
6. This associative array variable $arr_data needs to pass on json_encode() method. It enables conversion of array to JSON and returning JSON string you can check at result page.
7. Instead of echo() you can prefer print() method if you want and that not going to affects your result.
