从PHP中包含的文件中获取父文件的路径，我不需要文件夹路径，但是包含页面的完整路径

Question

I have a php file that could be included in different places. I need to have some rule on what to show depending on the including file.

Using $_SERVER['REQUEST_URI'] is returning the path of the page itself not the parent file that's including it.

Answer 1

Try:

<?php
echo $_SERVER['SCRIPT_FILENAME'];

The full list can be found on the PHP website .

Answer 2

I use spl_autoload_register so files are loaded when I use an instance of the class. I put all my global functions as public static functions of classes. I only have one include in my pages:

require "autoload.php";

The name of the page is the name of the class with a .php extension. Here's the code for my autoload.php page:

<?php
function my_autoload($sClassName)
{
    // LOAD THE CLASS.
    for($loop=0;$loop < strlen($sClassName);$loop++)
    {
        $thischar = substr($sClassName,$loop,1);
        if (($thischar != "_") && ((!ctype_alnum($thischar)) || (ctype_digit($thischar))))
        {
            // INVALID CLASS NAME.
            echo 'Class ' . $sClassName . ' has invalid characters.';
            return;
        }
    }
    $filename = dirname(__FILE__) . '/' . strtolower($sClassName) . '.php'; 
    if (file_exists($filename))
    {
        require($filename);
    } else
    {
        echo 'Error: file ' . $filename . ' not found looking for class ' . $sClassName;
    }
    return;
}
spl_autoload_register("my_autoload");
?>
