今天在Mac上使用Yii框架生成项目的时候，打印出一行warning，如下：
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/extensions/no-debug-non-zts-20090626/php_mysql.dll' - dlopen(/usr/lib/php/extensions/no-debug-non-zts-20090626/php_mysql.dll, 9): image not found in Unknown on line 0PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/extensions/no-debug-non-zts-20090626/php_mysqli.dll' - dlopen(/usr/lib/php/extensions/no-debug-non-zts-20090626/php_mysqli.dll, 9): image not found in Unknown on line 0百思不得其解，几经周折，在这找到了答案：http://superuser.com/questions/89176/php-warning-php-startup-unable-to-load-dynamic-library-php-mysql-dll-mac-10-6
记之。。。
