I am doing a very small online store application in PHP. So I have an array of maps in PHP. I want to search for a string (a product) in the array. I looked at array_search in PHP and it seems that it only looks for exact match. Do you guys know a better way to do this functionality? Since this is a very small part of what I am actually doing, I was hoping that there was something built in. Any ideas?
Thanks!
EDIT: The array contains "products" in this format:
[6] => SimpleXMLElement Object
(
[@attributes] => Array
(
[id] => 2000-YM
)
[Name] => Team Swim School T-Shirt
[size] => YM
[price] => 15
[group] => Team Clothing
[id] => 2000-YM
)
[7] => SimpleXMLElement Object
(
[@attributes] => Array
(
[id] => 3000-YS
)
[Name] => Youth Track Jacket
[size] => YS
[price] => 55
[group] => Team Clothing
[id] => 3000-YS
)
So I was wondering I can do a search such as "Team" and it would return me first item seen here. I am basing the search on the Name (again this is just something small). I understand that I can find the exact string, I am just stuck on the "best results" if it cannot find the exact item. Efficiency is nice but not required since I only have about 50 items so even if I use a "slow" algorithm it won't take much time.
array_filter
lets you specify a custom function to do the searching. In your case, a simple function that uses strpos()
to check if your search string is present:
function my_search($haystack) {
$needle = 'value to search for';
return(strpos($haystack, $needle)); // or stripos() if you want case-insensitive searching.
}
$matches = array_filter($your_array, 'my_search');
Alternatively, you could use an anonymous function to help prevent namespace contamination:
$matches = array_filter($your_array, function ($haystack) use ($needle) {
return(strpos($haystack, $needle));
});
