string question

[tgmdes]

Hi all.... i know this is a stupid one.. but i've been staring at my screen for an hour now.. Basically I'm trying strip off the last character of a string. In other words, I have a string that contains say .. $str="a,b,c,". This string will be used in an IN cluase for a sql query.. so that last comma is a bad thing... I'm trying to make the variable $str="a,b,c" i've done something like this in vbs using the left function... str = Left(str, Len(str) - 1)...(yes, yes, i know read up on the php manual). i am new to php coming from an asp background and am definitaly leaning in this direction... It's a great language!! Thanks in advance

Hi,
Here's a slapped together function to try. It strips the whitespace off the end before lopping of the last character.

<?
$str = "a,b,c,";
echo "old: $str<br>\n";
echo "new: " . rchop($str) . "<br>\n";

function rchop($str) {
// Remove right whitespace
$new = rtrim($str);
$new1 = substr($new,0,sizeof($new)-2);
return $new1;
}

?>

$test = "a,b,c,";
echo substr($test,0,strlen($test)-1);
