Foreach Loops

Foreach loops allow you to quickly traverse through an array.

$array = array("name" => "Jet", "occupation" => "Bounty Hunter" ); 
foreach ($array as $val) {
    echo "<P>$val";
}
Prints out:
<P>Jet
<P>Bounty Hunter

You can also use foreach loops to get the key of the values in the array:

foreach ($array as $key => $val) { 
    echo "<P>$key : $val";
}
Prints out:
<P>name : Jet
<P>occupation : Bounty Hunter
