Search array fvalues for partial match

Hello,

I am in need of a way to search an array for a value that contains a word.

$colorList = array("first name","last name","complete name","address","white");
$find = array_search("last", $colorList);
echo $find // results in $find being empty.

I need it to answer like the whole value would:

$colorList = array("first name","last name","complete name","address","white");
$find = array_search("last name", $cololorList);
echo $find // 1

So I need a partial match of the value to return the key and a way count the keys containing the partial value.

http://www.php.net/preg_grep

I knew there was a way..Great! Thanks.

So preg_grep returns an array of keys containing the specified text. How do I then search that array if a specific key exists? in_array seems to return false even though the array contains the value.
//search $start for values containing "minimum"
$second = preg_grep('#(Minimum)#i', $start);
//search $second for $value and return true or false
$value = 10;
if (in_array($value, $second)) {
echo "Yes!!!";
} else {
echo "No!!!";}

$second contains:
Array
(
[0] => 10
[1] => 27
)
Array
(
[0] => 10
[1] => 28
)
Array
(
[0] => 11
[1] => 30
)
Array
(
[0] => 10
[1] => 26
)

Always returns False and I do not understand why.

Im wondering if its because the value is a string. Not sure though but maybe try


if (in_array((string)$value, $second)) {
echo "Yes!!!";
} else {
echo "No!!!";}
