René,
This may not the most efficient method, but works:
$array = array('this sky is blue', 'pencils are orange', 'I like green apples','strawberries are red');
$search = 'green';
$result = array();
foreach($array as $key1=>$value1) {
if(substr_count($value1, $search)) {
$result[] = $key1;
}
}
// $result is an array containing all the keys for the values that contained the search phrase
print_r($result);
// or convert to string
print implode(' ', $result);
// or however else to need to handle the results
--Bob
