<li>
<p>In PHP, when handling file paths, dirname and pathinfo are both commonly used functions.</p>
</li>
<li>
<p>They are used to retrieve different parts of a path. This article explains their usage and whether they can be combined,</p>

<ul>
<li>
<p>dirname function</p>
</li>
<li></li>
<li>
<p>dirname() returns the parent directory path of the given path.</p>
</li>
<li>
<p>It can accept a second parameter to specify the number of levels to go up.<br>

<p>// Get the grandparent directory (two levels up)<br>

<li>
<p>pathinfo() returns an array containing directory name, basename, extension, and filename (without extension) of a file path.</p>

<p>You can also retrieve a specific part by passing a second parameter.<br>

<p>/**</p>
<ul>
<li>
<p>Can dirname and pathinfo be used together?</p>
</li>
<li></li>
<li>
<p>The answer is yes.</p>
</li>
<li>
<p>You can use dirname first to get the parent directory path, then use pathinfo to parse details of a higher-level path,</p>
</li>
<li>
<p>or combine both to handle different parts of the path separately.</p>
</li>
<li>
<p>For example, if you want to get the filename information of the parent directory of the file's directory, you can do this:<br>
*/</p>
</li>
</ul>
<p>$parentDir = dirname($filepath);<br>
echo "Directory of the file: $parentDir"\n";</p>
<p>// Parse the parent directory's path information<br>
$parentDirInfo = pathinfo($parentDir);<br>
echo "Parent directory path information:\n";<br>
print_r($parentDirInfo);</p>

<p>Summary:</p>
</li>
<li>
<ul>
<li>
<p>dirname is used to get the parent directory part of a path, suitable for recursive upward directory traversal.</p>

<p>pathinfo is used to get detailed information like directory name, filename, and extension in a path.</p>
