To delete a file in PHP, unlink() function is used. PHP unlink() function behaves same as UNIX C unlink() function. If the file is deleted successfully, it generates a TRUE value. If the file is not deleted successfully it generates a FALSE value or returns an E_WARNING level error.
Syntax:
bool unlink ( string $filename, context )
Filename: Â This is a mandatory parameter which specifies the name of the file to be deleted.
Context:  This is an optional parameter which specifies the context (set of options to modify a stream’s behaviour ) of the file handle.
Example:
<!DOCTYPE html> <html> <body> <?php $deletefile=unlink('phpfile.txt'); if($deletefile) { echo "File deleted."; } else { echo "Unable to Delete the File."; } ?> </body> </html> |
Output:
File deleted. |
