Choosing strpos() or strstr() or some other random string function for this common task feels dirty. Imagine if we had to use arrpos() instead of in_array() ;) Also, since strpos() is our official method, we must worry about 0 == false. Sorry for hijacking this thread, but it feels related. As for between(), creating a cookbook of common tasks (and inserting them into the manual) sounds reasonable. For example, we did something like this for the plethora of array sorting functions: http://php.net/array.sorting Regards, Philip
