echo $fileName;

To remove the file extension from a string in PHP, you can use the pathinfo() function to retrieve the extension and then use the str_replace() function to replace the extension with an empty string.

Here's an example code snippet that demonstrates how to remove the file extension in PHP:

1
2
3
4

<?php
$file = "example.txt";
$extension = pathinfo($file, PATHINFO_EXTENSION); // get the extension
$filename = str_replace("." . $extension, "", $file); // remove the extension
echo $filename; // outputs "example"
?>

In this example, we first define a string $file containing the filename with extension. We then use the pathinfo() function to retrieve the extension by passing the constant PATHINFO_EXTENSION as the second argument. We store the extension in the $extension variable.

Finally, we use the str_replace() function to replace the extension (including the dot) with an empty string. We store the resulting string in the $filename variable and then output it to the screen using the echo statement.
