Note Submitter: kriek@phpfreaks.com ---- This seems to be a common problem amongst new users. For some peculiar reason, they think that they can output data to the browser, and then send header information. Unfortunately, they are confusing the HTML meta-refresh tag with the PHP header() function. "cannot modify header information - headers already sent" Allow me to elaborate: That error is caused by because you are trying to send header information AFTER you have sent output to the browser. Usually this is a simple case of reordering an echo statement or removing white space before and/or after the PHP start and end tags (very common issue), however you can also use output buffering with the ob_start() and ob_end_flush() functions which will allow you to place headers and content in any order you want to. Note output buffering was originally designed to solve HTTP header errors. <?php ob_start(); // file content ob_end_flush(); ?> Although the ob_end_flush() function is not needed in MOST cases because it is called automatically at the end of script execution by PHP itself when output buffering is turned on either in the php.ini or by calling ob_start().
