phpinfo没看到mysql

我都重装了4遍了！看了n多的说明了！还是不行。是那里的问题呀！！论坛里也没说过吗？刚找了一下，没看到

把你的完整安装过程贴出来，我帮你看看哪的问题。

我下的是php5.2.5.zip解压到C:\Inetpub\php修改php.ini-recommended为php.ini和里面的参数（这个是看discuz.net改）再加入到iis里，显示正常。
安装mysql-5.0.45-win32.exe过程中正常在cmd下用mysql -u root -p 可以输密码 可以出现 mysql> 在用phpinfo.php检测的时候里面没看到mysql

我看到php.ini里面的
[MySQL]
; Allow or prevent persistent links.
mysql.allow_persistent = On

; Maximum number of persistent links.  -1 means no limit.
mysql.max_persistent = -1

; Maximum number of links (persistent + non-persistent).  -1 means no limit.
mysql.max_links = -1

; Default port number for mysql_connect().  If unset, mysql_connect() will use
; the $MYSQL_TCP_PORT or the mysql-tcp entry in /etc/services or the
; compile-time value defined MYSQL_PORT (in that order).  Win32 will only look
; at MYSQL_PORT.
mysql.default_port =

; Default socket name for local MySQL connects.  If empty, uses the built-in
; MySQL defaults.
mysql.default_socket =

; Default host for mysql_connect() (doesn't apply in safe mode).
mysql.default_host =

; Default user for mysql_connect() (doesn't apply in safe mode).
mysql.default_user =

; Default password for mysql_connect() (doesn't apply in safe mode).
; Note that this is generally a *bad* idea to store passwords in this file.
; *Any* user with PHP access can run 'echo get_cfg_var("mysql.default_password")
; and reveal this password!  And of course, any users with read access to this
; file will be able to reveal the password as well.
mysql.default_password =

; Maximum time (in seconds) for connect timeout. -1 means no limit
mysql.connect_timeout = 60

; Trace mode. When trace_mode is active (=On), warnings for table/index scans and
; SQL-Errors will be displayed.
mysql.trace_mode = Off
会不会跟这个有关呢？

我现在用Navicat for MySQL连接数据库 是可以！

刚安装了phpmysqmin显示

PHPMYADMIN設定問題

我也有相同的问题，网上说的方法都用过也不管用！！

mysql的扩展问题

解决办法是:去掉extension=php_mysql.dll 前面的 ；
然后重启web
