[PHP] How to format a strign with a generic mask??
Hi Folks,
First of all, sorry for my english, but it isn´t good. I ´ll try to be cleary. Weel, I
need a simple function that takes a string and format with a generic mask. Like this
example above:
$string1 = "12345678"
$string2 = "11062003"
echo format_string ("#.###.###-#", $string1); // --> Returns 1.234.567-8
echo format_string ("##/##/", $string1); // --> Returns 11/06/2003
Does anybody here have an idea to how to do this?
Thanks, and sorry again for my english.

Re: [PHP] How to find if a string is an integer?
try this:
if (ereg("^[0-9]+$", $_POST["var_int"))
echo "is int";

Sorry, I don´t know that you needed an effective snipet. And you are right,
I only writed for positive integers. Try something like apply 2 type cast
simunltaneous.
if ( (string) ((int) $_POST["var_int"]) == $_POST["var_int"])
echo "is int";
And sorry for my english,
