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'>".$nav."</a></li>";
}
The output is like this:
Is there a function or a way that could be used removing ../ prefix from the output string ?
Thank you.
You'll probably get all kinds of wacky string manipulation answers, so here is the proper tool:
basename — Returns trailing name component of path
Which is exactly what you are doing:
basename($nav)
Also, use GLOB_ONLYDIR flag as the second argument in your glob() call if you only want directories.
Sure, you can use str_replace, but I'd go with AbraCadaver's answer...
$dirs = array_filter(glob('../*'), 'is_dir');
foreach ($dirs as $nav) {
$nav = str_replace("../", "", $nav);
echo "<li><a href='$nav'>$nav</a></li>";
}
You can subtract 3 chars from beginnings like this:
echo substr($string, 3);
