Looks to me that the bracketing is wrong...

if (substr($sString,(strlen($sString)-1)!=-)) {
I think you meant either
substr($sString,strlen($sString)-2)
or
substr($sString,-1)
print You can't have a dash at the end of your string.;
}
and this works:
if (substr($sString,0,1)!=-) {
print You can't have a dash at the beginning of your string.;
}
But, this doesn't work for any case:
if ((substr($sString,(strlen($sString)-1)!=-)) or
(substr($sString,0,1)!=-)) {
print you can't have a dash at the beginning or end of your
string.;
}
What could be wrong? I've used a logical OR operator in the
middle of an
IF
statement like this before, but for some reason, this just isn't
working.
Anyone got any ideas? I suppose I can just evaluate this with two
different
IF statements, but it seems like I shoud be able to do it in one
and
reduce
duplicate code. Thanks very much in advance.

[PHP] Re: Using Logical OR operator in IF statement???
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...

[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.
