PHP Delete File

In PHP, we can delete any file using unlink() function. The unlink() function accepts one argument only: file name. It is similar to UNIX C unlink() function.

PHP unlink() generates E_WARNING level error if file is not deleted. It returns TRUE if file is deleted successfully otherwise FALSE.

Syntax

bool unlink ( string $filename [, resource $context ] )  

$filename represents the name of the file to be deleted.

PHP Delete File Example

<?php      
$status=unlink('data.txt');    
if($status){  
echo "File deleted successfully";    
}else{  
echo "Sorry!";    
}  
?>  

Output

File deleted successfully
