php.ini 常見設定

php.ini檔案位置/etc/php5/apache2/php.ini
php-fpm檔案位置/etc/php5/fpm/php.ini
而php cli位置應該是在 /etc/php5/cli/php.ini

sudo vim /etc/php5/apache2/php.ini
# or
sudo vim /etc/php5/fpm/php.ini
# or
sudo vim /etc/php5/cli/php.ini

可以用下列指令確認

php -i |grep php\.ini

我個人常用的設定為(for debug):

short_open_tag=On
memory_limit=2000M
error_reporting=E_ALL & ~E_DEPRECATED & ~E_NOTICE & ~E_STRICT
display_error=On
post_max_size=20000M
upload_max_filesize=20000M
max_file_uploads=200

其中,memory_limit > post_max_size > upload_max_filesize

修改之後,得要重新啟動apache2

sudo /etc/init.d/apache2 restart
# or
sudo service apache2 restart

vim 快速修改方式:

#for apache2
sudo vim /etc/php5/apache2/php.ini
