Another approach is by using regular expressions.

<pre><code>$fileName = basename($filePath);
$fileNameNoExtension = preg_replace("/\.[^.]+$/", "", $fileName);
</code></pre>

This removes from the last period <code>.</code> up until the end of the string.

Below is the one line code that returns the filename only and removes extension name:

blocks|key|1126431|text|如果你知道扩展名，@Gordon+basename将会工作得很好，如果你不知道，你可以使用explode：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1126432|$filename+=+end(explode(".",+$file));|code-block|syntax|javascript|1126433|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

$ext+=+pathinfo($path,+PATHINFO_EXTENSION);

@fire incase the filename uses dots, you could get the wrong output.
I would use @Gordon method but get the extension too, so the basename function works with all extensions, like this:

<pre><code>$path = "/home/httpd/html/index.php";
$ext = pathinfo($path, PATHINFO_EXTENSION);

$file = basename($path, ".".$ext); // $file is set to "index"

print array_shift(explode(".", basename($path)));
// will print "sudoers"

$file = "file_name.php"; 
print array_shift(explode(".", basename($file)));
// will print "file_name"

I have this PHP code:

<pre><code>function ShowFileExtension($filepath)
{
 preg_match('/[^?]*/', $filepath, $matches);
 $string = $matches[0];

 $pattern = preg_split('/\./', $string, -1, PREG_SPLIT_OFFSET_CAPTURE);

 if(count($pattern) &gt; 1)
 {
 $filenamepart = $pattern[count($pattern)-1][0];
 preg_match('/[^?]*/', $filenamepart, $matches);
 return strtolower($matches[0]);
 }
}
</code></pre>

If I have a file named <code>my.zip</code>, this function returns <code>.zip</code>.

I want to do the reverse, I want the function to return <code>my</code> without the extension.

The file is just a string in a variable.

PHP, get file name without file extension

我有以下PHP代码：function ShowFileExtension($filepath){    preg_match('/[^?]*/', $filepath, $matches);    $string = $matches[0];    $pattern = preg_split('/\./', $string, -1, PREG_SPLIT_OFFSET_CAPTURE);    i
