dl(domxml.so)?

[sand123]

In my PHP installed
/usr/lib/php4/domxml.so
/usr/lib/php4/mysql.so

there are these files..

But still it gives the following error when i run like following script
<?
dl("domxml.so");
.
.
?>

dl(): Unable to load dynamic library '/usr/local/apache2/php/lib/php/extensions/no-debug-non-zts-20020429/mysql.so' - /usr/local/apache2/php/lib/php/extensions/no-debug-non-zts-20020429/mysql.so: cannot open shared object file: No such file or directory in /home/safesquid/register/common.php on line 3

I also included 'domxml.so' file in the same directory..
but still it gives the error...🙁
