wamp 无法加载 mysqli 扩展

Question

新手上路，请多包涵

WAMP 安装正常，没问题，但是……

当转到 phpMyAdmin 时，我从 phpMyAdmin 得到如下错误：

 Cannot load mysqli extension. Please check your PHP configuration

此外，phpMyAdmin 文档对此错误消息的解释如下：

要连接到 MySQL 服务器，PHP 需要一组称为“MySQL 扩展”的 MySQL 函数。此扩展可能是 PHP 发行版的一部分（内置编译），否则需要动态加载。它的名字可能是 mysql.so 或 php_mysql.dll。 phpMyAdmin 尝试加载扩展但失败了。通常，问题是通过安装一个名为“PHP-MySQL”或类似的软件包来解决的。

最后，apache_error.log 文件有以下 PHP 警告（请参阅 mySQL 警告）：

 PHP Warning: Zend Optimizer does not support this version of PHP - please upgrade to the latest version of Zend Optimizer in Unknown on line 0
PHP Warning: Zend Platform does not support this version of PHP - please upgrade to the latest version of Zend Platform in Unknown on line 0
PHP Warning: Zend Debug Server does not support this version of PHP - please upgrade to the latest version of Zend Debug Server in Unknown on line 0
PHP Warning: gd wrapper does not support this version of PHP - please upgrade to the latest version of gd wrapper in Unknown on line 0
PHP Warning: java wrapper does not support this version of PHP - please upgrade to the latest version of java wrapper in Unknown on line 0
PHP Warning: mysql wrapper does not support this version of PHP - please upgrade to the latest version of mysql wrapper in Unknown on line 0

所以，出于某种原因，PHP 无法识别 mysql 扩展。

有人知道为什么吗？任何解决方案或解决方法？
