Initial Description
I used to program in classic ASP and would sometimes check if a certain word or letter would be in a string with instr.
if instr(haystack, needle)>0 then
DO SOMETHING
end if
If the needle starts on the first position of the haystack, instr returns 1.
If the needle is not in the haystack, instr returns 0.
PHP has the strpos and stripos functions which return FALSE if the needle is not in the haystack and return 0 if the needle starts on the first position of the haystack.
I wanted to be able to do a quick check on a string, without checking type so I created the instr function for PHP.
if (instr($haystack, $needle)>0)
{
DO SOMETHING
}
(an offset can be given but is optional)
