    Gets the target of a link

    说明

    publicSplFileInfo::getLinkTarget(void): string

    Gets the target of a filesystem link.

    Note:

    The target may not be the real path on the filesystem. Use SplFileInfo::getRealPath() to determine the true path on the filesystem.

    返回值

    Returns the target of the filesystem link.

    错误/异常

    Throws RuntimeException on error.

    范例

    SplFileInfo::getLinkTarget() example

    <?php
    $info = new SplFileInfo('/Users/bbieber/workspace');
    if ($info->isLink()) {
        var_dump($info->getLinkTarget());
        var_dump($info->getRealPath());
    }
    ?>
    

    以上例程的输出类似于:

    string(19) "Documents/workspace"
    string(34) "/Users/bbieber/Documents/workspace"
