SplFileInfo::getLinkTarget — Gets the target of a link
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.
此函数没有参数。
Returns the target of the filesystem link.
Throws RuntimeException on error.
Example #1 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"
