比如说我有这个
$word = "Hello";
$word1 = "my";
$word2 = "name is";
$word3 = "Shankar";
我希望能够在循环中调用每个变量名,并使用每个变量名后缀的数字来标识它们
这就是我所做的
$x = '';
while($x <= 3){
$y = $word . $x;
$x++;
echo $y . "<br>";
}
但是我一直得到这个结果
Hello
Hello1
Hello2
Hello3
这就是我想要的
Hello
my
name is
Shankar

更改
$y = $word . $x;
到
$y = ${"word" . $x};

我认为这将帮助您实现目标
$prefix = 'word';
$x = '';
while($x <= 3){
$variable = $prefix.$x;
$output = $$variable; //by adding the dollar sign you have then refered to it as a variable
echo $output . '<br />';
$x++;
}

始终使用数组存储数据集。它将代码简化为:
$words = ["Hello", "my", "name is", "Shankar"];
echo implode("\n", $words);
