php - 如何用其他TextArea循环TextArea中的每一行

Question

基本上，我有两个 3 textareas
这样的：

First textarea:
test
test2
test3
Second textarea:   
fizz
fizz2
fizz3
Third textarea:
buzz
buzz2
buzz3

我希望循环获取第一个 textarea 的第一行并使用第二个 textarea 的第一行和第三个 textarea 的第一行打印它
示例：

test => fizz => buzz
test => fizz => buzz2
test => fizz => buzz3

test => fizz2 => buzz
test => fizz2 => buzz2
test => fizz2 => buzz3

test => fizz3 => buzz
test => fizz3 => buzz2
test => fizz3 => buzz3

然后当它像那样打印时，它会转到第一个文本区域中的下一行test2并打印相同的内容。
我一直在使用这段代码不起作用，我认为整个问题在于将增量放在哪里，但我尝试了很多行

    $ta1 = explode(PHP_EOL, $valid);
    $xx = 0;
    $yy = 0;
    $zz = 0;
    foreach ($ta1 as $key => $value) {
        $ta = $ta1[$xx];
            $usr = explode(PHP_EOL, $users);
            foreach ($usr as $key => $value) {
                $user = $usr[$yy];
                $pwd = explode(PHP_EOL, $passwords);
                $yy++;
                foreach ($pwd as $key => $value) {
                    $pass = $pwd[$zz];
                    echo "F: $ta User: $user Password: $pass" . "<br>";
                    $zz++;
                    $xx++;
