It's used in key value combinations in several places.
When building an array:
$foo = array('key' => 'value', 'another_key' => 'another value');
which will give you an array that looks like
$foo['key'] = 'value';
$foo['another_key'] = 'another_value';
Also, in foreach(), which is a language construct used to iterate over arrays:
foreach($foo as $key => $val) {
echo "The key for this element is $key and the value is $val\n";
}
will output:
The key for this element is key and the value is value
The key for this element is another_key and the value is another_value
Those are the two most common places you'll see it (and perhaps the
only, I don't want to speak conclusively, though, I'm awfully tired
this evening!)
