how do you replace a value with an array of values several times?

$find_array = array('foo','bar');
$replace_array = array('moo','car');

$string = 'foo bar';
echo str_replace($find_array, $replace_array, $string);

//outputs
moo car

everyone does replace with both find an array and the replace an array. how do you do it with just the replace an array?

Because, the occurance of the first element in the replace array would overwrite all occurances of the find making the additional replaces irrelevant.
