Hi,
I try do to a < simple > thing :
Knowing If a string like "13" exist in a string like "123"
Or if "37" exist in "12356789"
I tried many solutions, but never found one good so I try to do it with
loops which more difficult but not impossible
I'd like to know if with RegExp it's more simply
If you just want to see if the string "13" is found within the string
"123", you can use the index() function:
$found = index('123', '13') >= 0;
==> false
or a simple regex:
$found = '123' =~ /13/;
==> false
If you want to know whether '123' contains both a '1' and a '3', you can
do something like this:
$found = !grep $_ < 0, map index('123', $_), split '', '13';
==> true
