[Resolved] trimming the last character from a tring IF it is a certain character

[markdw]

I have searched fro an answer, and I feel it is probably possible with rtrim but I havent yet figured out exactly how....

My string may or may not have a | as the last character. If it does, I want to remove it, if not, leave the string as is.

Many thanks in advance! Mark

it ought to be

rtrim($my_string, "|");

or

rtrim ($my_string, '|');

some of these functions act slightly differently depending upon single or double quotes.

well that is what i thought, but i get..

Warning: Wrong parameter count for rtrim() in /home/sites/site20/web/BackOffice/Property/EditProperty.php on line 683

$MyString = "blah|blah|";
rtrim($MyString ,'|');

The warning suggest you are running somethin earlier than php 4.1. I checked the manual and the second param was added in 4.1

More disturbingly, I tested it on my system and the function din't actually strip the | at the end of the line.

If you are stuck with this problem I guess you could do something inelegant like;

check the final char with:

$char = substr($MySrray, -1) //gets the end char

then check it

if ($char == '|') {
$stripped_string = substr($MyString, 0, -1);

}

that's ugly but should work - the final piece comes straight from the manual under substr.

Well, it works!

$strLastChar = substr($strVar, -1);
if ($strLastChar == "|")
	{
	$strVar = substr($strVar, 0, -1);
	}

Thanks for your help!
