PHP: Delete a File

You are searching for the function unlink(), to which you can just pass the filename of the file that should be deleted.

For example, you can use the function like that:

$f = 'test.dat';

if (file_exists($f)) {
   unlink($f);
} else {
   echo 'File not found!';
}

In this example, first we are using the function file_exists() to check whether the file "test.dat" exists. If yes, we are deleting the file using unlink().

Here is another small example for using the unlink() function provided by PHP:

$fh = fopen('test.txt', 'a');
fwrite($fh, 'Content of File');
fclose($fh);

unlink('test.txt');

First, we are creating a simple text file called "test.txt" and after that, we are writing "Content of File" into the file. Then, we are immediately deleting the file using the function unlink().
