To easy:

 

<?php
$strings = array(
    'apple blue green',
    'apple yellow not',
    'apple something blue',
    'apple drugs car yellow'
);

$wordcounts = array();
foreach ($strings as $string) {
    $words = explode(' ', $string);
    foreach ($words as $word) {
        if (isset($wordcounts[$word])) {
            ++$wordcounts[$word];
        } else {
            $wordcounts[$word] = 1;
        }
    }
}

print_r($wordcounts);
?>
