1.在Apache中加載PHP
LoadModule php5_module X:/php/php5apache2_2.dll
PHPIniDir "X:/php"
需要注意的是dll對應的apache版本，也就是php5apache后面的數字。
2.在PHP5中連接MySQL5
PHP5中已經不直接支持MySQL了，需要自己手動配置，官方網站中是這樣說明的：
MySQL is supported with the only change being that MySQL support is no longer enabled by default in PHP 5. This essentially means that PHP doesn't include the --with-mysql option in the configure line so that you must now manually do this when compiling PHP. Windows users will edit php.ini and enable the php_mysql.dll DLL as in PHP 4 no such DLL existed, it was simply built into your Windows PHP binaries.
Also, the MySQL client libraries are no longer bundled with PHP. More details on this topic are covered in the following FAQ and be sure to read the MySQL section for details on installing MySQL. An example configure line would be --with-mysql=/usr while Windows users will need the libmySQL.dll available to the system.
先修改php.ini的內容
extension_dir = "X:\php\ext"
并去掉下面兩項的分號
extension=php_mysql.dll
extension=php_mysqli.dll
然后，將php目錄下的libmysql.dll拷貝到C:\Windows目錄，之后MySQL就可以正常連接了。
寫個程序來測試一下吧。
1 <?php
2 $link = mysql_connect("localhost", "username", "password")
3 or die("Could not connect: " . mysql_error());
4 print ("Connected successfully");
5 mysql_close($link);
6 ?>
