Chops off the last character of a string and returns the character chopped. It is much more efficient thans/.$//s because it neither scans nor copies the string. If VARIABLE is omitted, chops$_. If VARIABLE is a hash, it chops the hash's values, but not its keys, resetting theeach iterator in the process.
You can actually chop anything that's an lvalue, including an assignment.
If you chop a list, each element is chopped. Only the value of the lastchop is returned.
Note thatchop returns the last character. To return all but the last character, usesubstr($string, 0, -1).
