删除字符串的3个第一个字符

Question

I have this code that shows all the directories in the previous page.

$dirs = array_filter(glob('../*'), 'is_dir');

foreach ($dirs as $nav) {
    echo "<li><a href='$nav'>".$nav."</a></li>";
}

The output is like this:

• ../Gėlės
• ../dddd
• ../images

Is there a function or a way that could be used removing ../ prefix from the output string ?

Thank you.

You'll probably get all kinds of wacky string manipulation answers, so here is the proper tool:

basename — Returns trailing name component of path

Which is exactly what you are doing:

basename($nav)

Also, use GLOB_ONLYDIR flag as the second argument in your glob() call if you only want directories.
