最近在做一个项目的时候发现,在php中,如果要对一个数据的某个元素进行赋值的时候,就会报错如:

php
$str="222222";
$var=array(
         a
=>"1",
         b
=>$str,
         c
=>""
);
if($var[b]){
       
$var[c]=$var[b];
}
?> 
会提示出错,说明未定义常量。
这种情况有俩个方法可以解决,一就是更改php.ini的配置
修改php.ini,把error_reporting        =        E_ALL改成
error_reporting        =        E_ALL    &    ~E_NOTICE
如果这种不能解决的话,
就把

 替换成
