Question

I have an array

$test = array('one', 'two', 'three', 'four', 'five');

I unset two and four (because I really really dislike even numbers)

unset($test[array_search('two', $test)]);
unset($test[array_search('four', $test)]);

And am left with an array

$test = array(
[0] => 'one',
[2] => 'three',
[4] => 'five'
);

Now I need to loop through that array and obtain the value along with the correct key. I want to display

0 = one
2 = three
4 = five

What should I use to achieve that? I tried using standard

for($i=0; $i<count($test); $i++)

but that is not effective because it will loop and give me 0 1 2 instead of 0 2 4.
Any suggestions?

You can use a foreach loop for this

foreach($test as $key => $value) {
echo "$key = $value";
}

Read about foreach loop at at php.net manual
