Want to delete a PHP Session?

March 15th, 2007 by Quatrux

A lot of PHP novice programmers which don’t want to understand how the sessions work in the beginning, usually doesn’t delete a session the right way, so I wanted to post an example PHP script session_delete(); which deletes everything as needed.

PHP [Show Styled Code]:


function session_delete($sname = 'Current User') {
	# Set Session Name to a Variable
	$name = session_name();
	/* Empty the Cookie from Session */
	if (!headers_sent() ) { setcookie($name,"",0,"/"); }
	/* Remove the Cookie Value */
	unset($_COOKIE[$name]);
	/* Remove all the Info from the Super Global */
	$_SESSION = array();
	/* Free all session variables */
	session_unset();
	/* Destroy all data registered to a session */
	if (session_destroy() === FALSE) {
		return FALSE;
	} else {
		return TRUE;
	}
}

PHP [Show Plain Code]:

function session_delete($sname = ‘Current User’) {
        # Set Session Name to a Variable
        $name = session_name();
        /* Empty the Cookie from Session */
        if (!headers_sent() ) { setcookie($name,"",0,"/"); }
        /* Remove the Cookie Value */
        unset($_COOKIE[$name]);
        /* Remove all the Info from the Super Global */
        $_SESSION = array();
        /* Free all session variables */
        session_unset();
        /* Destroy all data registered to a session */
        if (session_destroy() === FALSE) {
                return FALSE;
        } else {
                return TRUE;
        }       
}
