You can also use stripos

Find the position of the first occurrence of a case-insensitive substring in a string

if(stripos("This is a test string","A Test")!==FALSE)
{
    echo "Yes";
}

Check this note for stristr from manual:

Note: If you only want to determine if a particular needle occurs within haystack, use the faster and less memory intensive function strpos() instead.

Use stristr

Returns the matched substring. If needle is not found, returns FALSE. 

if(stristr("Hello","hello world")!==FALSE)
{
  // Yes needle is a part of haystack
}
