Permutations

I'am looking for a small script that will take two words from two different arrays and will make combinations of 2.

Examples:

first array:

red, blue, green

PHP:

second array:

cat, elephant, monkey

PHP:

the result should be like this:

red cat
red elephant
red monkey
blue cat
blue elephant
blue monkey
green cat
green elephant
green monkey

PHP:

but not combinations like "cat monkey"

 

following might help.. please make modifications according to your convenience..

<?php
	
	$arr1 = array('red', 'blue', 'green');
	$arr2 = array('cat', 'elephant', 'monkey');
	
	$arr_perm = get_permutations($arr1, $arr2);
	print_r($arr_perm);
	
	function get_permutations($array1, $array2)
	{
		$result = '';
		foreach($array1 as $elem1)
		{
			foreach($array2 as $elem2)
			{
				$result[] = $elem1 . ' ' . $elem2;
			}
		}
		return $result;
	}
	
?>

PHP:

 

$colors = array('red', 'blue', 'green');
$animals = array('cat', 'elephant', 'monkey');

foreach ($colors as $color) {
	foreach ($animals as $animal) {
		echo $color . " " . $animal . "<br />";
	}
}

PHP:

Can't test it but it should work as expected.

 

Thanks, both work.
