    I’m receiving a warning after editing or deleting a record:
    Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\aptana\header.php:14) in C:\xampp\htdocs\aptana\edit.php on line 17

    Apparently it’s caused by whitespace, but there doesn’t seem to be any in the header file.
    Any ideas?

    For some reason I cannot reproduce this error on my machine. I think XAMPP may be using another instance of PHP that I have on my machine.

    Either way, I am pretty sure this error is caused by the leading output from header.php file. This can be easily fixed by adding ob_start(); as a first line of PHP code in header.php file. This will enable output buffering, which means that PHP will not produce any output until the page execution is finished.
