echo $data; // sending back to jquery

Thanks in advance

I don't know if its just for me but your variable: $_POST[“mydata”] should have proper quotations like $_POST[''mydata] — Darren

Use proper quotes and use isset() to check the data set or not like,

<?php
    header('Access-Control-Allow-Origin: *'); // this is to allow another domain    
    print_r($_POST);// to check the post data
    $data = isset($_POST['mydata']) ? $_POST['mydata'] : "No Data";
    echo $data; // sending back to jquery
?>

Try to get the POST variable with single quotes and better to put exit after echoing it like

$data = $_POST['mydata'];
echo $data; 
exit;

And make sure that it is posting to the given URL or not through console.

OK,It walk well when I test it.In order to reappear the error you've got,I'm trying to set the file.php into a BOM-UTF8 file and it got error in the end.So,please check your file.php if it got a BOM before header().

Another suggess,you can use firebug to test your ajax post process.The link in the console will show you the ajax process,such as what you've post and what is feedback.Just use console.log() instead of alert().
