PHP在字符串文字中动态引用变量 [英] PHP dynamically reference variable in string literal

问题描述

我有多个PHP变量，形式为

I have multiple PHP variables in the form

$number1, $number2, $number3 and so on...

我想在循环中动态地引用这些内容以从中检索信息，但不知道如何动态引用静态变量。例如：$（$ i = 1; $ i = 10; $ i ++）{
//

I would like to dynamically reference these inside of a loop to retrieve information from them, but am not sure how to reference the static variable dynamically. Ex:

for($i = 1; $i <= 10; $i++) {
    //The first number to be printed should be the value from
    //$number1 not $number concatenated to $i

    //here are some of the strings I tried:
    echo "$number$i";
    echo "{$number}$i";
    echo "{$number}{$i}";
}

推荐答案

应该这样做： / p>

This should do it:

echo ${"number{$i}"};

但是为什么不使用数组？ $ number [$ i] 更易读...

But why not use arrays instead? Having $number[$i] is much more readable...
