Bug description: Suggestion for new "substring exists" function
Description:
------------
What we often need to test for is just whether a substring exists or
not. For example this is very common in examining a user agent.
Currently you can use strpos, but you have to be careful to test only
with two specific formulations, using the strict equivalency
operators:
if (strpos($x, $y) === FALSE)
or
if (strpos($x, $y) !== FALSE)
That "anti-FALSE" approach is generally awkward, and if you use == or
!= by mistake you'll have ambiguity with a substring position of
number 0.
It would be handy and much less prone to syntax mistakes, to have a
dedicated "string exists" function which returns only TRUE or FALSE.
This might be "strex" or "strpres" ("string present").
Plus an equivalent case sensitive version -- striex or stripres.
