find the name of a file in php

To find the name of a file in PHP, you can use the basename() function. This function returns the base name of a file path, which is the last component of the path.

Here's an example:

main.php
$path = "/path/to/myfile.txt";
$filename = basename($path);
echo $filename; // outputs "myfile.txt"
100 chars
4 lines

In this example, we first define the file path using a string. We then pass this path to the basename() function, which returns the file name as a string. We can then use echo to output the name to the screen.

If you're working with a file uploaded via a form, you can use basename() to get the file name from its temporary location:

main.php
$filename = basename($_FILES["file"]["tmp_name"]);
echo $filename; // outputs the name of the uploaded file
108 chars
3 lines

Note that in this case, we're accessing the tmp_name property of the $_FILES array, which contains the temporary name of the uploaded file on the server. We can then pass this to basename() as before to get the file name.
