查找PHP的配置文件
先写了一个
<?php
phpinfo();
?>
然后在浏览器中浏览一下（之前我百度说在Configuration File 这个位置看）
结果竟然显示 Loaded Configuration File none ；
让别人问了问才知道。需要把源码包中的文件复制过去才行
cp /usr/local/src/php-5.3.28/php.ini-production /usr/local/php/etc/php.ini
然后再重新启动apache，
| Loaded Configuration File | /usr/local/php/etc/php.ini |
显示正常。另一个查看配置文件文件的方法
/usr/local/php/bin/php -i |head
phpinfo()
