In case my initial description is confusing, I mean...
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)
Otherwise you will have ambiguity with a substring position of number
0.

Description:
------------
What we often need to test for is just whether a substring exists or
not. This is very common, for example, in examining a user agent.
Currently you have to test for these specific formulations, being very
careful to use the strict equivalency operators:
strpos === FALSE
or
strpos !== FALSE
It would be handy and much less prone to incorrect syntax use to have a
"string exists" function -- maybe as strex or strpres ("string present")
-- dedicated to this, which returns only TRUE or FALSE.
There could also be a "case sensitive string exists" -- maybe as striex
or stripres.
