Need code quick! 25 NP$! URGENT

mholt · 11-05-2005, 09:43 AM

hey,

I need a quick PHP code that does this:

Finds whether a hyphen is the FIRST character in a string OR LAST character.

E.g. It displays an error for this:

-test

And this:

test-

But not this:

te-st

or....

tes-t

Etc. Just first and last character. 25 NP$ to the person who can write up this PHP code real quick, I can't figure it out for some reason.

Thanks,
-Matt

if(substr($var, -1, 1) == '-' OR substr($var, 0, 1) == '-') {
echo "Error";
}

wouldn't you have to find the total chars in the word first, then look back 1?

Look at http://us2.php.net/substr
