How can I change the strpos to make it non case sensitive. The reason is if the product->name
is MadBike and the search term is bike it will not echo me the link.
My main concern is the speed of the code.
<?php
$xml = simplexml_load_file('test.xml');
$searchterm = "bike";
foreach ($xml->product as $product) {
if (strpos($product->name, $searchterm) !== false ) {
echo $product->link;
} }
?>
You're looking for stripos()
If that isn't available to you, then just call strtolower()
on both strings first.
EDIT:
stripos()
won't work if you want to find a substring with diacritical sign.
For example:
stripos("Leży Jerzy na wieży i nie wierzy, że na wieży leży dużo JEŻY","jeży");
returns false
, but it should return int(68)
.
