华为云11月刊推送:DIY微信问答机器人,高性能计算代码的20个技巧!>>>

今天在我的Ubuntu-12.04上coding,php版本是5.3.10-1ubuntu3.4,在var_dump($_ENV);的时候发现是空,查了手册,$_ENV是记录环境变量的数组,我让我同学试了一下看能否输出东西,他的是xp的系统,php5.2版本。

然后我就去上网查,网上说要把php.ini中的一个设置修改掉,我打开了php.ini,找到了variables order这个设置,发现默认没有设置,网上说要设置成EGPCS,查看了手册,发现variables order属于php核心设置,每个字母都代表了一个意思,E(Environment), G(Get), P(Post), C(Cookie), 和S(Server),手册上说,如果你设置为SP,php将会创建超全局变量,$_SERVER和$_POST,不会创建$_ENV,$_GET和$_Cookie,总算搞定了,本来以为这样就可以了,但是又出现了一个奇怪的事情,就是关于var_dump的

在没有配置这个选项之前,var_dump()一个数组的时候是这样子的




但是修改之后,var_dump的时候是这样子的



本人很奇怪,是不是php5.3.10有个调试模式什么的,小问题,求解答,求解惑

PHP5.4中的var_dump默认就是这个模式的

更方便调试时查看问题,没有什么大惊小怪的。。。

目测楼主也开启了xdebug, xdebug会美化var_dump的输出
