To delete a file by using PHP is very easy. Deleting a file means completely erase a file from a directory so that the file is no longer exist. PHP has an unlink[] function that allows to delete a file. The PHP unlink[] function takes two parameters $filename and $context. Syntax:

unlink[ $filename, $context ];

Below programs illustrate the above approach: Program 1: This program uses unlink[] function to remove file from directory. Suppose there is a file named as “gfg.txt” 

php

Output:

gfg.txt has been deleted

Program 2: This program uses unlink[] function to delete a file from folder after using some operation. 

php

Output:

Warning: unlink[] expects parameter 1 to be a valid path, resource

Resource id #3 cannot be deleted due to an error

Note: If the file does not exist then it will display an error.
