Answer 1

您可以这样做：

$arr = array('FIRSTNAME','LASTNAME','MIDDLENAME','PHONE');

$i = 0;
foreach (range('A', 'D') as $alphabet) {
    echo $alphabet .'-'. $arr[$i] . '\n';
    $i++;
}

PHP＆gt; 7：

<?php
$phrases = [
    'FIRSTNAME', 
    'LASTNAME', 
    'MIDDLENAME',
    'PHONE'
];
$chars  = range('A','Z');
foreach ($phrases as $index => $phrase) {
    echo ($chars[$index] ?? '?') . ' => ' . $phrase;
}

PHP＆lt; 7：

<?php
$phrases = [
    'FIRSTNAME', 
    'LASTNAME', 
    'MIDDLENAME',
    'PHONE'
];
$chars  = range('A','Z');
foreach ($phrases as $index => $phrase) {
    echo (isset($chars[$index]) ? $chars[$index] : '?') . ' => ' . $phrase;
}

Answer 3

<?php 

   $alphabet = range('A','D');


   for ($i = 0; $i<4; $i++){

      echo nl2br($alphabet[$i]."-FIRSTNAME\n");
      echo nl2br($alphabet[$i]."-LASTNAME\n");
      echo nl2br($alphabet[$i]."-MIDDLENAME\n");
      echo nl2br($alphabet[$i]."-PHONE\n");
      echo nl2br("\n");
      echo nl2br("\n");
  }

?>
