Passing data from PHP to JavaScript
Have you ever needed to send a PHP variable, array, or object to JavaScript? It can get complicated trying to escape the output properly. Here’s a way that always works—no escaping necessary.
Let’s say we have the following variable in PHP:
- $name = ‘Bob Marley’;
And we want to pass it to a JavaScript variable called name. Here’s the trick:
- echo ‘<script>’;
- echo ‘var name = ‘ . json_encode($name) . ‘;’;
- echo ‘</script>’;
Using json_encode(), you’ll always get a properly formatted JavaScript object.
