Does php assign value to js array?

PHP can assign values ​​to JS arrays, because both PHP and JS can operate arrays, but their syntax is different.

A common way is to create an array in PHP and then convert it to a JS array. For example:

$phpArray = array('apple', 'banana', 'orange');
$jsArray = json_encode($phpArray);

Here, we first create a PHP array $phpArray, and then use the json_encode() function to convert it to a JS array. json_encode()The function encodes a PHP array into a JSON string, which can be used directly in JS.

Now we can use this array in JS:

var fruits = <?php echo $jsArray; ?>;
console.log(fruits); // ["apple", "banana", "orange"]

Here, we embed $jsArray into the JS code using the echo statement Output a JS array string and assign it to the JS variable fruits.

Of course, this method can also use other methods to generate JS arrays, such as:

$phpArray = array('apple', 'banana', 'orange');
$jsArray = '[' . implode(',', $phpArray) . ']';

Here, we first use the implode() function to convert the PHP array into Comma-separated strings, and then use [] brackets to concatenate them into the string format of a JS array.

No matter which way, converting PHP and JS arrays is very easy. Just understand the basic syntax and data types of both.
