How to make strpos case insensitive
PhpStrposPhp Problem Overview
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;
} }
?>
Php Solutions
Solution 1 - Php
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).
Solution 2 - Php

stripos() is not case-sensitive.
Solution 3 - Php
'i' in stripos() means case insensitive
if(stripos($product->name, $searchterm) !== false){ //'i' case insensitive
echo "Match = ".$product->link."<br />;
}
Solution 4 - Php
make both name & $searchterm lowercase prior to $strpos.
$haystack = strtolower($product->name);
$needle = strtolower($searchterm);
if(strpos($haystack, $needle) !== false){
echo "Match = ".$product->link."<br />;
}
