PHP循环动态变量

本文介绍了PHP循环动态变量的处理方法，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

我正在尝试创建一个动态变量.我有一个循环，我希望它循环遍历记录并为每个记录创建一个变量.我的代码:

I am trying to create a dynamic variable. I have a loop and I want it to loop through the records and create a variable for each record. My code:

$ct = 1; foreach ($record as $rec){ $var.$ct = $rec['Name']; $ct = $ct + 1; } echo $var1;

当我尝试使用上面的代码时，它给我一个错误，提示$var1变量不存在/未定义?在PHP中是否可以像上面的示例一样创建动态变量.如果是这样，我在做什么错?

When I try to use the above code, it gives me an error saying the $var1 variable doesn't exist/undefined? Is it possible in PHP to create dynamic variables like the above example. If so, what am I doing wrong?

推荐答案

您正在寻找变量.

将变量名创建为字符串，然后分配它:

Create the variable name as a string, and then assign it:

$ct = 1; foreach( $record as $rec ) { $name = 'var'.$ct; $$name = $rec['Name']; $ct++; } echo $var1;

创建数组会更好，

$names = [ ]; foreach( $record as $rec ) { $names[] = $rec['Name']; } echo $names[0];
