函数在localhost上起作用，但在服务器上不起作用

Question

I made a function to get the main folder path in which website is stored. In localhost it works fine.

function get_path()
{

    $current=dirname(__FILE__) . '/';   
    $name=basename(__DIR__);
    $from=array($name);
    $to=array('');
    $result=str_replace($from,$to,$current);    

return trim($result, "/\\");
}

But in server it shows error while including files.

 include(): Failed opening 'home3/home/public_html/dev/ship\model\main.php' for inclusion (include_path='.:/opt/php54/lib/php') 

The file is there in that directory for sure. But its not working.

Answer 1

您正在去除第一个斜杠（第一个字符）-加上您在路径中使用\\而不是/。

Answer 2

Try the following

// Define directory separator
define('DS', DIRECTORY_SEPARATOR);

function get_path()
{

    $current = dirname(__FILE__) . DS;
    $name = basename(__DIR__);
    $from = array($name);
    $to = array('');
    $result = str_replace($from, $to, $current);

    return $result;
}

Or you could use:

// define directory separator
define('DS', DIRECTORY_SEPARATOR);

function get_path($withSlash = true)
{
    $path = realpath(dirname(__FILE__));
    if ($trailingSlash) {
        $path .= DS;
    }
    return $path;
}

Answer 3

为了创建路径，您应该使用PHP函数realpath来管理斜杠： http : //php.net/realpath
