PHP is entirely evaluated at the server side before its sent to the browser. So that means the first code block will work without any issues. The second code block will fail when PHP parses the code.
What PHP does is scans, parses, evaluates the code between <?php & ?>. It will simply ignore and send the content outside of this block to the browser -- blindly. This means that your <script> tags are sent to the browser, so that the javascript engine is able to work without any problems.
The second block of code will fail when PHP parses the content: <?php .. <script> .. </script> ?>
it won't work, if your purpose is to "hide" your javascript logic try obfuscating your javascript code.
for example: http://www.javascriptobfuscator.com/Default.aspx
The answer is "You , you can" echo out Javascript from within PHP. And you can use PHP inside Javascript tags.
But remember, the PHP code is always processed FIRST on the server.
Then the HTML with Javascript is sent to the client.
And then the Javascript is run at the client machine.
As thrustmaster said, PHP is entirely evaluated at the server side.
You can make the second block of code work by echoing the script:
<?php
// PHP goes here
echo '<script>';
// JavaScript goes here
echo '</script>';
?>
echo " <script type=\"text/javascript\"> alert('a testing'); </script> "; ?> i mean everything inside echo statementYes, you can use PHP code in <script> tags.
Suppose a request has been made to load your index.php file and you have following code in this file :
$demo = "Demo of PHP in Script Tag.";
//
//Some PHP code
//
<script type="text/javascript">
var a = "<?php echo $demo; ?>";
</script>
//
// Some PHP code
//
//End of file.
Now when you check value of javascript variable a, you will find: "Demo of PHP in Script Tag."
For checking value of javascript variable you can either alert it or check using firebug.
and for script tags in php tags you have echo your script like :
<?php
echo "<script type="text/javascript">/*script here */</script>";
?>
Hope this will helps you.
