Question

At the minute I have a page with an AJAX script that searches a database with LIKE ‘%search term from input box%’.

I need to modify it so that instead of searching the database it searches an array (that has been constructed from two tables – I can’t use a JOIN because there’s a bit more to it than that).

How do I go about creating a fuzzy search function in PHP that will return all the possible matches from the array?

Answer 1

you want preg_grep

e.g.

$arr = array("tom jones", "tom smith", "bob jones", "jon smith");
$results = preg_grep("/jones/",$arr);

$results will now contain two elements, "tom jones" and "bob jones"
