PHP array search with given key word from array

Question

I have a search text field, and an array I want to output below.

This is my array:

array=["abc","abcde","ab","abcdef"];

When I enter "ab" in the text field, then the list should appear. "ab" should come first.

ab,
abc,
abcde,
abcdef,

If I type "abc" then list should show:

abc,
abcde,
abcdef,

This should solve your little issue

<?php
$input = preg_quote('cde', '~'); // don't forget to quote input string!
$array=["abc","abcde","ab","abcdef"];
$result = preg_grep('~' . $input . '~', $array);
foreach ($result as $val) {
    echo "$val\n";
}
?>
