PHP查看ini文件，查看配置文件路径

方法一（推荐）：php -i | grep Configuration

[root@localhost ~]# php -i | grep Configuration
Configuration File (php.ini) Path => /etc
Loaded Configuration File => /etc/php.ini
Configuration

Loaded Configuration File 即php.ini配置文件路径

方法二：whereis php.ini

[root@localhost ~]# whereis php.ini
php: /usr/bin/php /usr/lib64/php /etc/php.d /etc/php.ini /usr/include/php /usr/share/php /usr/share/man/man1/php.1.gz

此方法，会返回很多数据，需要自行辨别。

方法三：php --ini

[root@localhost ~]# php --ini
