public function _protect( $fullPath )
    {
    fullPath = strtr( $fullPath, ":*<>|\"\x00\\", "......./" ); 这句代码是什么意思？ 显示错误

fullPath -> $fullPath
$fullPath  = strtr($fullPath, ":*<>|\"\x00\\", "......./" ); //转换指定字符串

<?php
$trans = array("hello" => "hi", "hi" => "hello");
echo strtr("hi all, I said hello", $trans);
?>

以上例程会输出：

hello all, I said hi

函数名差了个$符号……
