.
Right.
The pattern does not match anything in the input string of
$Arra
> $Pattern = "(http://)?([^[:space:]]+)([[:alnum:]\.,-_?/&=])";
> $Replace = "http://\\2\\3\"; target=\"_new\">\\2\\3";
> $Array["URL"] = eregi_replace($Pattern, $Replace, $Array["URL"]);
>
> print ("Your submission--$Array[URL]--has been received!\n");
That does no checking or validation at all.
