此函数是该函数的别名: rtrim()。
Note:
chop() 与 Perl 的 chop() 函数有所不同,它会删除字符串的最后一个字符。

This function corresponds more or less to the PERL chomp() function.

Another possible one would be to use this:
<?php
function chup(){
$ar=Array();
foreach(func_get_args() as $b) {
push($ar,$b[strlen($b)-1]);
&$b[strlen($b)-1]='';
}
return $ar;
}
?>
If you wanted to perl-chop a va list of strings and return the removed chars. Obviously you can easily mod it for va list arrays of strings and the like.
