That's weird! Today's Apache and IIS are unable to load php_mysql.dll correctly. Google a bit, the original found that there are many people this problem, PHP startup:unable to load dynamic Library:e;\php5\ext\php_mysql.dll. Obviously Php_mysql.dll is placed in extension_dir (= "E:/php5/ext") under the well, how can it? And in the Php_mysql.dll before the Extension=php_gd2.dll did not appear this problem, strange! Some people say that copy Libmysql.dll to%windir%\system32 can solve the problem, in fact, "Huashan not this Way":

PHP was moved by me,%programfiles% to e:\, causing some extensions to be dependent on other DLLs to work properly loading these DLLs, and loading them up
Wrong, to just php_mysql.dll for example, Php_mysql rely on Libmysql.dll, due to PHP5 Novo, and did not put the new E:\PHP5 aisle%path%
, so it's impossible to find this libmysql.dll. So in order to be able to use these MySQL extensions, in addition to properly configure Extension_dir outside
, you also have to ensure that the system is able to rely on the DLLs that these extensions depend on, with two solutions:
1 copy these dependent DLLs to the%windir%\system32
2 or add the PHP5 installation directory to the%path%.
Whatever it is, it can achieve our goal.
It's simple enough, but sometimes I can't think of where to go.
