you need
ereg()
or one of the preg_
regular expressions, google for
"ereg php function"
to see many examples of its power.
you could use
ereg( '^[a-zA-Z0-9]*[A-Z]{2,}[a-zA-Z0-9]*$', $testcase );
this means
at the start of testcase ^
zero ore more * characters of type a-z or A-Z or 0-9
followed by 2 or more {2,} characters within A-Z range
ended $
by zero or more a-z A-Z or 0-9 characters.
you can even make SURE that the conditions are complied with by using
ereg_replace()
