Different ways to remove an extension from a filename in PHP

1. Using pathinfo() function
2. Using basename() function
3. Using substr() and strrpos() functions
4. Using regular expression

1. Using pathinfo() function

The `pathinfo()` inbuilt PHP function returns an array containing the directory `name`, `basename`, `extension` and `filename`. To get only the filename, we can use `PATHINFO_FILENAME` as shown below.

<!--?php
$filename = 'myfilename.php';
$without_ext = pathinfo($filename, PATHINFO_FILENAME);
echo $without_ext;
?-->

// Output: myfilename

2. Using basename() function

The `basename()` inbuilt function is used when you know the extension of the file and pass it to the basename function to remove the extension from the filename.

<!--?php
$filename = 'myfilename.php';
$without_ext = basename($filename, '.php');
echo $without_ext;
?-->

// Output: myfilename

3. Using substr() and strrpos() functions

We can also remove the file extension using `substr()` and `strrpos()` functions. The `substr()` function returns the part of the string whereas `strrpos()` finds the position of the last occurrence of substring in a string.

<!--?php
$filename = 'myfilename.php';
$without_ext = substr($filename, 0, strrpos($filename, "."));
echo $without_ext;
?-->

// Output: myfilename

4. Using regular expression

Also, we can use the regular expression to get a filename without extension.

<!--?php
$filename = 'myfilename.php';
$without_ext = preg_replace('/.[^.]*$/', '', $filename);
echo $without_ext;
?-->

// Output: myfilename
