AJAX xmlhttp.responseText from php echo 1

[waytech2003]

First off let me say I am new to php and AJAX.
I am fairly good in javascript and HTML.
I am working on a new project.
I have an AJAX XMLHttpRequest sent to a php page, which returns a string via echo.
Example of my return responce would be this as the last 2 lines in my php page.

echo "TEST";
?>

I get back what looks like "TEST" in an alert box, alert(xmlhttp.responseText);
but if I test it against a string it fails. When I check it as follows...
alert(xmlhttp.responseText=="TEST");
I get false.
Is php sending something I do not know about in the echo command?

Hi

You probably have an empty line after the closing PHP tag and as you know, content outside the PHP tags is sent out unaltered.

That is why is recommended to not close the PHP tag at the end of the file. Remove the closing tag and your JavaScript will probably work. ( Unless you have some static content before the opening tag too. )

Thanks feherke you are correct.

I found that by trimming blank spaces off my xmlhttp.responseText, in the receiving page, all is now OK.
