Stripping char in PHP

[HumanClay]

I want to strip the last character in a variable in PHP. HOw do I do this? i.e.

$var = "words";

I want to be able to strip that "s" off the end of the word. I forgot how to do this ... Thanks.

If it's Perl you can use the function chop ;o)

$var = "words";
chop($var);

I'm sorry, I didn't know what was PHP. After readind all the messages now I know!
So I guess you'll receive a better answer soon!
Good luck!

Yeah, too bad I couldn't find it either, but you could use substr() for this:

substr(string,0,strlen(string)-2);

I would go with what Son said except shouldn't be
$var = substr($var,0,strlen($var)-1);

Oh yeah, Freddy! I thought the substr has syntax like this: substr(str,startIndex,endIndex)
But it is: substr(str,startIndex,lengthToGrasp);

So yes, it should be what Freddy gave ya!

Thanks. It worked.

Alternatively, using regular expressions:

$var = ereg_replace("^(.*).$","\\1",$var);

Just a note: with reg. expression, the cost is performance if you use it many times
