PHP: Remove last Character from String

You can use the PHP function substr() for this purpose.

In order to remove the last character from the string, you have to pass 0 as first parameter and -1 as second parameter.

$s = "abcde";

echo substr($s, 0, -1);  // abcd

The second parameter is specifying from which character position the string should be copied. The first character is the character 0 and because we do not want to remove anything from the front, we are accordingly using 0 as the second parameter.

The third parameter is specifying the length of the substring. A negative value means that it is counted from behind. That is why we are passing -1 to get the last character.
