Say I have an path: images/alphabet/abc/23345.jpg
How do I remove the file at the end from the path? So I end up with: images/aphabet/abc/
You want dirname()
<?php
$path = pathinfo('images/alphabet/abc/23345.jpg');
echo $path['dirname'];
?>
dirname()
only gives you the parent folder's name , sodirname()
will fail wherepathinfo()
will not .
For that, you should use pathinfo()
:
$dirname = pathinfo('images/alphabet/abc/23345.jpg', PATHINFO_DIRNAME);
The PATHINFO_DIRNAME
tells pathinfo
to directly return the dirname
.
See some examples:
For path images/alphabet/abc/23345.jpg
, both works:
<?php $dirname = dirname('images/alphabet/abc/23345.jpg'); // $dirname === 'images/alphabet/abc/' $dirname = pathinfo('images/alphabet/abc/23345.jpg', PATHINFO_DIRNAME); // $dirname === 'images/alphabet/abc/'
For path images/alphabet/abc/
, where dirname
fails:
<?php $dirname = dirname('images/alphabet/abc/'); // $dirname === 'images/alphabet/' $dirname = pathinfo('images/alphabet/abc/', PATHINFO_DIRNAME); // $dirname === 'images/alphabet/abc/'
Note that when a string contains only a filename without a path (eg "test.txt"
), the dirname()
and pathinfo()
functions return a single dot ( "."
) as a directory, instead of an empty string. And if your string ends with "/"
, ie when a string contains only path without filename, these functions ignore this ending slash and return you a parent directory. In some cases this may be undesirable behavior and you need to use something else. For example, if your path may contain only forward slashes "/"
, ie only one variant (not both slash "/"
and backslash "\"
) then you can use this function:
function stripFileName(string $path): string
{
if (($pos = strrpos($path, '/')) !== false) {
return substr($path, 0, $pos);
} else {
return '';
}
}
Or the same thing little shorter, but less clear:
function stripFileName(string $path): string
{
return substr($path, 0, (int) strrpos($path, '/'));
}
