在循环内将变量设置为全局范围

本文介绍了在循环内将变量设置为全局范围的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我想在PHP中定义一些临时全局变量，名为

因为您使用'字符串

尝试
为您的目的
$ b $ pre $ for（$ i = 1; $ i {
// acess as $ GlOBALS ['MyGlobalVar'。$ i]并做任何你想做的事
$ GLOBALS ['MyGlobalVar'。$ i] = null
}

I want to define a number of temporary global variables in PHP called $MyGlobalVar1, $MyGlobalVar2 ... , but the problem is that the keyword 'global' takes the variable name literally:

for ($i = 1; $i<= 10; $i++) { 
    $var = '$MyGlobalVar'.$i;
    global $var;
}

i.e. $var is now global.

Setting quotes will not work because 'global' expects '$' and will stop execution at the single quote:

for ($i = 1; $i<= 10; $i++) { 
    $var = '$MyGlobalVar'.$i;
    global '$var';
}

How to set the variables to global scope? Thanks.

解决方案

since you using ' it will always be taken as string

Try$GLOBALS for your purpose

for ($i = 1; $i<= 10; $i++)
 { 
// acess as $GlOBALS['MyGlobalVar'.$i] and do whatever you want
   $GLOBALS['MyGlobalVar'.$i] = null
}
