How to get php variable to JavaScript variable

Answer 1

You can do this

var js = "<?php echo $var ?>";

Answer 2

To pass scalar data held in a PHP variable ( $val ) to a JavaScript variable, place the following in a JavaScript segment: var val = " <?php echo $val ?> "; Notice the quotes around the PHP tags. This will result in a string value in JavaScript which you may need to convert for use in your scripts.

Answer 3

The two options are presented by @Toni and @WASP.

@Toni's approach involves dynamically writing the JavaScript on the PHP page during the initial page request. Your static JS can then run based on the initialized value.

@WASP's approach involves loading the PHP generated page on the client, then using AJAX to make a secondary call via Javascript to request the value as JSON or even XML.

Which of these options best fit your situation?

Answer 4

If you send the variables as query strings you should be able to get them in JS. It's the fastest way I can think of at the moment.
