How to convert array to JavaScript object in PHP
In web development, it is often necessary to pass server-side data to client-side JavaScript. In order to facilitate the transfer and use of data, we can convert server-side PHP arrays into JavaScript objects or arrays.
Convert PHP array to JavaScript object
Let’s first look at a simple PHP array:
$data = array( 'name' => 'Tom', 'age' => 18, 'gender' => 'male' );
We can use PHP’s json_encode()
function to convert it Convert to a string in JSON format, and then use the JSON.parse()
function in JavaScript to convert it to a JavaScript object:
var jsonString = '<?php echo json_encode($data); ?>'; var data = JSON.parse(jsonString); console.log(data.name); // 输出 Tom console.log(data.age); // 输出 18 console.log(data.gender); // 输出 male
As you can see, use json_encode() The
function converts a PHP array into a JSON-formatted string is very simple, and then it is also convenient to use the JSON.parse()
function in JavaScript to convert it into a JavaScript object.
Convert PHP array to JavaScript array
It is also a PHP array, and we can use the same method to convert it to a JavaScript array. Just use the index array in PHP:
$data = array('apple', 'banana', 'orange');
Then convert it to a string in JSON format, and then use the JSON.parse()
function in JavaScript to convert it to JavaScript Arrays:
var jsonString = '<?php echo json_encode($data); ?>'; var data = JSON.parse(jsonString); console.log(data[0]); // 输出 apple console.log(data[1]); // 输出 banana console.log(data[2]); // 输出 orange
Just like converting a PHP array to a JavaScript object, converting it to a JavaScript array is very simple.
Note
When converting a PHP array into a JSON format string, you need to use the json_encode()
function. In PHP 5.2.0 and above, this function is built-in and no extension is required. In older versions of PHP, the JSON extension needs to be installed.
When passing a JavaScript object or array to the server side, we can also convert it to a JSON format string, and then use the json_decode()
function in PHP to convert it to PHP object or array.
Summary
PHP arrays can be easily converted into JSON-formatted strings. Use the JSON.parse()
function in JavaScript to convert them into JavaScript objects or array. This method is very convenient and can well solve the problem of data transmission and use.
