Looks to me that the bracketing is wrong...
try:
if ((substr($sString,(strlen($sString)-1))!="-") or

[PHP] Re: Using Logical OR operator in IF statement???
Thanks James,
I tried a regular expression comparison first, but it was eluding me. I'm
new to PHP (trying to convert form ASP) and part of this is me trying to
convert my ASP/VBSCRIPT to PHP. ;-) I actually have a FOR loop evaluated
when the conditions of the IF statement are met, and I suspect that is
messing things up. Here's my entire code and I've used your expression
comparison instead but it still fails to find the "-" unless I split things
up and check either ONLY for the '-' at the beginning or the end, but not
both in the same line:
function StringCheck($sString)
{
if (preg_match("/^-|-$/s", $sString))
{
for ( $counter=0; $counter < strlen($sString); $counter++ )
{
$nChar = ord(strtolower(substr($sString, $counter, 1)));
if (($nChar > 47 And $nChar < 58) or ($nChar > 96 And $nChar < 123) or
($nChar == 45))
{
$result = TRUE;
}
else
{
$result = FALSE;
break;
}
}
}
else
{
$result = FALSE;
}
return $result;
} //End Function StringCheck
Maybe you see something I don't. I can't get over the fact that if I check
for just the front, or the end, it works, but if I check for both the front
and end of the string in the same line with the OR, it fails. :-\ Thanks
in advance for any thing you might notice.

Hi Brad,
This worked for me:
.. but I'd tend to go for a regex as a solution to what you're after,
which involves less code:
Just my thoughts...
