Pass a php string into JQuery

Question

I have a php function which I am using to calculate statistics of information in a database. I want to output the results in a string and pass it to JQuery to be able to make graphical representations of the data.

Is it possible to pass a string from PHP into a JQuery method in this way?

Thanks in advance

Answer 1

Jquery is javascript was executed by browser.

Set the header as javascript on your php and load with script tag.

<script type="text/javascript" src="/yourphpfile.php"></script

And then in file yourphpfile.php

<?php
 header('Content-type:application/javascript');
 $stringFromDb = functionGetContentFromDB();
?>
var data = "<?= $stringFromDb ?>";

Answer 2

 <?php
 $var = "somestring";
 echo '<script>var str = "'.$var.'";</script>';
 ?>

you can do that this way

Answer 3

There are two ways, you can output this into the javascript onload, echoing to the inline javascript.

<script>
 var string = "<?php echo $string; ?>";
</script>

Alternatively you can fetch the data from ajax using json_encode in php to get the data in the correct format.

If you then use getJson (http://api.jquery.com/jQuery.getJSON/) you will have the data in the correct format.
