在家里電腦上自己做的項(xiàng)目图筹，移到外網(wǎng)上時(shí)出現(xiàn)大量如下提示：

猛的一看，有點(diǎn)懵了丧荐，本來(lái)調(diào)試的好好的屎开，怎么會(huì)突然出現(xiàn)錯(cuò)誤碉钠？
翻譯了下提示的意思流妻，才明白原來(lái)PHP中允許中變量不經(jīng)過(guò)聲明而直接使用驹马，但是如果設(shè)置了error_reporting后所有錯(cuò)誤全顯示的話革砸，就會(huì)就出現(xiàn)提示，所以我們?cè)趯懘a時(shí)最好養(yǎng)成習(xí)慣糯累，變量使用前最好先聲明
解決方案自然是設(shè)置下error_reporting打開(kāi)php.ini將error_reporting = E_ALL 后面加上 & ~E_NOTICE
或者在全局配置文件里寫error_reporting(0)
