I have used ez_sql in the past and I wish to thank you for a great class.

However I have a problem since I uninstalled and re-installed XAMPP on my PC.

Before the re-installation, ez_demo.php ran fine. After installation I get the error I attach below. And yes, I have set the host, database, username and password correctly, and yes the database server is running! I can run my own PHP scripts that connect and use the mysql database fine, but ez_demo.php refuses to run and gives the following error every time. Any ideas gratefully received:

dbh = @mysql_connect($dbhost,$dbuser,$dbpassword); if ( ! $this->dbh ) { $this->print_error("

1. Error establishing a database connection!Are you sure you have the correct user/password?
2. Are you sure that you have typed the correct hostname?
3. Are you sure that the database server is running?

"); } $this->select($dbname); } // ================================================================== // Select a DB (if another one needs to be selected) function select($db) { if ( !@mysql_select_db($db,$this->dbh)) { $this->print_error("

1. Error selecting database $db!Are you sure it exists?
2. Are you sure there is a valid database connection?

"); } } // ================================================================== // Print SQL/DB error. function print_error($str = "") { if ( !$str ) $str = mysql_error(); // If there is an error then take note of it print "

I have tried many different things to solve this, and spent many hours Googling for an answer, but the only thing that solves it is reverting from XAMPP 1.7.2 (the latest) back to an older version, XAMPP 1.7.0.

I believe your package is incompatible with either the latest PHP, or the latest MySQL.
