session_start() doesn't need to be the first line of your PHP code, it just needs to be called before any other output is performed. Including any blank spaces or anything else. If you have: --- 1: 2: <?php 3: session_start(); 4: ?> --- It's not going to work because you have a blank line being output to the browser for interpretation. Same problem would occur if you even had: --- 1: <?php // Leading single blank space character 2: session_start(); 3: ?> --- Output buffering may help in some cases, but I'd look at the error where it says: "output started at /var/www/html/index.php:9" Sounds like there's a way to solve this without resorting to output buffering. In addition to the basic command reference listed below, check out the user contributed comments on these pages: http://www.php.net/manual/en/function.session-start.php http://www.php.net/manual/en/function.ob-start.php According to the first comment, ob_end_flush() is called automatically at the end of your script, so it's not mandatory that you use it (but probably good 'complete' programming practice).
