I seen a strange (space) before response I got from Ajax.response text. Each time i fire my Ajax it sends some variables and activates php script and returns a string as Ajax.response text.

After some tinkering i found that even if i echo "nothing" I get a space before this static string too. what can cause this strange thing to happen ?

Ajax declaration :

function ajaxObj(meth, url) {
var x = new XMLHttpRequest();
x.open(meth, url, true);
x.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
return x;
}
function ajaxReturn(x){
if(x.readyState === 4 && x.status === 200){
    return true;    
}
}

PHP script :

<?php
if (isset($_POST['pattern']))   
{     
echo "nothing" ;
exit();
}?>

My Observations :

No effect after removing exit function.
No space before php and ajax decalration.
Firebug says " nothing".
Tried in all browsers.

Perhaps an utf8 BOM? Make sure your php file is saved without it. – jeroen Sep 17 '16 at 17:40
Check if there is `auto_prepend_file ` in `php.ini`. Also look at [http://stackoverflow.com/q/10072569/5962802](http://stackoverflow.com/q/10072569/5962802) – IVO GELOV Sep 17 '16 at 17:41

php files are saved without utf8 inside php files – akash raigade Sep 17 '16 at 18:29
you might have left some a newline after closing the php tag on some of your file. this might be an issue – Nitin9791 Sep 17 '16 at 18:46
Yes sir i forget to add that i also checked for spaces after and before php tags too . – akash raigade Sep 17 '16 at 22:28
