How to make strpos case insensitive

Question

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; } } ?> JavaScript questions and answers, JavaScript questions pdf, JavaScript question bank, JavaScript questions and answers pdf, mcq on JavaScript pdf, JavaScript questions and solutions, JavaScript mcq Test , Interview JavaScript questions, JavaScript Questions for Interview, JavaScript MCQ (Multiple Choice Questions)

Answer 1

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).
