Hi Abdou, The " Call to undefined function ..." error is usually caused by an extension that provides that function that is not loaded or is not available. 1. Make sure that you have the php_mysql.dll extension on the PHP extension dir. 2. Furthermore if the extension exists check that it is properly loaded by looking through your php.ini file for 'extension=php_mysql.dll' HTH Jervin > -----Original Message----- > From: Abdou Karim Jallow [mailto:akjallow@xxxxxxxxxxxxxx] > Sent: Thursday, November 16, 2006 12:04 AM > To: php-db@xxxxxxxxxxxxx > Subject: Installation Problem > > I have just upgraded to PHP 5.2 from PHP 4.
