How to make strpos case insensitive

php strpos

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).

php strpos

stripos() is not case-sensitive.

php strpos

'i' in stripos() means case insensitive

if(stripos($product->name, $searchterm) !== false){ //'i' case insensitive        echo "Match = ".$product->link."<br />;    }
