Hi Brad,
This worked for me:
<?
if ((substr($sString, 0, (strlen($sString)-1) == "-")) || (substr($sString,
0, 1) == "-")) {
echo "you can't have a dash at the beginning or end of your string.";
}
?>
...... but I'd tend to go for a regex as a solution to what you're after,
which involves less code:
<?
if (preg_match("/^-|-$/s", $string)) {
echo "You cannot have a \"-\" character at the beginning or end of your
string.";
} else {
echo "Whatever....";
}
?>
Just my thoughts...
