How can I loop through the members of an array?

If you want to create a quick and easy loop to show the values of an array, then all you need is the trusty foreach control structure, thus:


<?php

$alphabet = range("A","Z");

foreach($alphabet as $letter) { echo "Ooh look!  The letter $letter\n"; }

?>

Prints this:

Ooh look! The letter A
Ooh look! The letter B
Ooh look! The letter C
Ooh look! The letter D
Ooh look! The letter E
Ooh look! The letter F
Ooh look! The letter G
Ooh look! The letter H
Ooh look! The letter I
Ooh look! The letter J
Ooh look! The letter K
Ooh look! The letter L
Ooh look! The letter M
Ooh look! The letter N
Ooh look! The letter O
Ooh look! The letter P
Ooh look! The letter Q
Ooh look! The letter R
Ooh look! The letter S
Ooh look! The letter T
Ooh look! The letter U
Ooh look! The letter V
Ooh look! The letter W
Ooh look! The letter X
Ooh look! The letter Y
Ooh look! The letter Z
