Something about PHP
1: Allowed memory size of 16777216 bytes exhaustedThis is caused by the memory leak, which is set in php.ini, 16M is default size, so you can change it larger the option in php.ini file is :
step 1 : reset the size
memory_limit = 16M
step 2 : restart the apache
service apache2 restart
(BTW, I am in Unbutu)
2: The difference betweenmysql and mysqli mysql是非持继连接函数而mysqli是永远连接函数。也就是说mysql每次链接都会打开一个连接的进程而mysqli多次运行mysqli将使用同一连接进程,从而减少了服务器的开销
