How would you mix these foreach loops into one?

Say I have this loop.

foreach($record as $row) {
   <div class="hello">Hello World!</div>
}

I want to loop through and add a letter alongside the "Hello World!" above.  To do that, I found this code.

$azRange = range('A', 'Z');
foreach ($azRange as $letter) {
  print("$letter\n");
}

How can I combine the two loops so that I get a result like this?

A Hello World!
B Hello World!
C Hello World!
D Hello World!
E Hello World!
F Hello World!

I assume your “Hello World!” should actually be a dynamic string depending on $row?

 

The easiest way to implement parallel iteration is to iterate one array with a foreach loop and the other with repeated each() calls:

<?php

$record = range(1, 26);   // test data
$letters = range('A', 'Z');

foreach ($record as $row)
{
    $letterElement = each($letters);
    assert($letterElement !== false, 'Not enough letters for number of rows.');
    $letter = $letterElement['value'];

    echo "$letter: $row<br>";
}

For more complex scenarios, there are also iterator classes in the SPL extension.
