php 设置error_reporting(0)和ini_set('display_errors', 0)之后,还是显示错误

php 5.4
apache 2.2

php 设置error_reporting(0)和ini_set('display_errors', 0)之后,还是显示错误
关闭错误报告和错误显示
php 设置error_reporting(0)和ini_set('display_errors', 0)之后,还是显示错误
依然会显示错误

按照我的理解,error_reporting(0)之后就应该不会显示错误了,这是怎么回事?

后来我又试着在php.ini者.htaccess中将display_errors设为off,才抑制了错误报告的显示。

而根据PHP手册中的描述

display_errors指令是属于 PHP_INI_ALL 因而就可以在任何地方被设定,包括ini_set() 。

这又是怎么回事?

PHP不是一行一行去解析然后执行的,如果这样上下文根本无法绑定起来。是一个文件一个文件去解析的。像你这样一个文件没有解析成功,那么这整个文件的代码都无法执行的。 你可以放在 include 的文件里面将你的 sdfsdf 放里面看看。要保证主文件是可编译通过的,再试试

<?php
error_reporting(0);
Copy after login

PS:不是PHP没有执行是你写的代码没有执行。

在PHP代码的第一行就加上这句,可以屏蔽一些非关键的报错。
比如你的输入的这段代码,只是变量$system_path没有被定义。
PHP默认没有定义的变量会报错。

只要通过

<?php
ini_set("error_reporting",E_ALL ^ E_NOTICE);
Copy after login

就可以屏蔽非关键的报错。
而一旦出现比这个更高级的错误,都属于会让整个PHP网站无法运行的关键错误。

屏蔽错误不利于自己Debug,慎用。
