Removing last character of a string

I had a string that looked like:
2;4;6;7;
The string is dynamic, so it could also be:
3;5;2;8;9;
I needed to remove the last ; (semicolon) from the string but wasn’t sure what the best method of doing this was. I thought about using the strlen() (string length) function. Get the value of how long the string is, and then removed the last character using substr(). The task seems a bit tedious and unefficient though.
So I searched Google to find the best method, and stumbled upon the answer to my question — How do you remove the last character of a string?
The solution is to use:
$outgoing = substr_replace($incoming,"",-1);
So if I use:
$outgoing = substr_replace('3;5;2;8;9;',"",-1);
My output would be:
3;5;2;8;9
Exactly what I was looking for! Thank you Graham Ellis!

substr() is probably the easiest, but you don’t have to use strlen(). Straight from the PHP manual:
$rest = substr("abcdef", 0, -1); // returns "abcde"This function will take the target string and string to look for and remove as an argument.
//Trim string and remove specified trailing string;
function removeCharacter($whichData,$whichString) {
$whichData = trim($whichData);
if(substr($whichData,strlen($whichData)-1) == $whichString) {
$whichData = substr($whichData,0,strlen($whichData)-1);
}
return $whichData;
};
rtrim($var,”;”)
hope this helps
Is there a way to take all but the last string?
Do you mean the last character?
echo substr(‘abcdef’, -1, 1);
This will return just the ‘f’.
That is another great piece of code. :) Thank you!
Thanks!
You’re welcome. :)
