[SOLVED] Remove Last New Line

[The Little Guy]

For some reason, I can't think of why I can't figure this out, so basically I have string with multiple lines, and I would like remove the last \n but not sure how...

 

So this is how I make the string:

$params = '';
for($i=0;$i<count($_POST['param']);$i++){
if(strlen(str_replace(' ', '',$_POST['param'][$i])) > 0)
	$params .= $_POST['param'][$i].'|'.$_POST['paramdesc'][$i]."\n";
}

 

Now, there is ALWAYS one \n at the end of $params when the loop is finished. I would like to remove that \n, but I am not sure how. The trim function doesn't work, it removes them all or something, because when I use it, I get an empty string...

try...

<?php
$params = '';
for($i=0;$i<count($_POST['param']);$i++){
if(strlen(str_replace(' ', '',$_POST['param'][$i])) > 0)
	$params .= $_POST['param'][$i].'|'.$_POST['paramdesc'][$i]."\n";
}
$params = substr($params,-2);

 

or something to that affect.

perfect! Thanks!

 

only one modification:

 

$params = substr($params, 0, -2);
