This is a test-thing from one of my projects. The problem is the LOCK TABLES not beeing unlocked again.. This is a userproblem, but can sometimes be hard to track when you rerun the script, and hit another Apache-PID and tables still beeing locked.. maybe when a Link identifier is destroyed, or new database is selected, an "UNLOCK TABLES" should be ommited?

testsource from project:

<?
unset ( $ROOT ); $ROOT = "../";
include_once ( $ROOT."include/setup.php" ); 
include_once ( $INCLUDE."mysql.php" );

MySQL_DoConnect();
echo "Locking..."; 
mysql_query("LOCK TABLES Ansatt WRITE;");
echo "Done (".mysql_error().")<br>";
?>
