In PHP5 (including BETA), mysql is loaded as a module, and php. ini needs to be set for loading. for example:
Extension_dir = "D:/www/WebServer/PHP5/ext /"
Extension = php_mysql.dll

In addition, both PHP4 and PHP5 require libmysql in the system directory. dll support. if the version is incorrect, even if you have set the extension_dir and php_mysql.dll parameters correctly, the error phpp_mysql.dll cannot be found during apache startup.
