Ftp_delete()

Understanding the PHP Function ftp_delete()

The ftp_delete() function is a PHP built-in function that is used to delete a file on a remote FTP server. The function takes two parameters:

1. ftp_stream: The connection identifier returned by the ftp_connect() function.
2. filename: The name of the file you want to delete.

The function returns a boolean value. If the function is successful in deleting the file, it returns true. Otherwise, it returns false.

Syntax of ftp_delete()

The syntax of the ftp_delete() function is as follows:

bool ftp_delete ( resource $ftp_stream , string $filename )

The ftp_delete() function takes two parameters: ftp_stream and filename. The ftp_stream parameter is the connection identifier returned by the ftp_connect() function. The filename parameter is the name of the file you want to delete.

Usage of ftp_delete()

To use the ftp_delete() function, you first need to establish a connection to the FTP server using the ftp_connect() function. Here's an example:

<?php

// Set up an FTP connection
$conn = ftp_connect('ftp.example.com');

// Login with your FTP credentials
ftp_login($conn, 'username', 'password');

// Delete the file
ftp_delete($conn, '/path/to/file.txt');

// Close the connection
ftp_close($conn);

In this example, we establish a connection to the FTP server using the ftp_connect() function. Then we log in using our FTP credentials using the ftp_login() function. Finally, we delete the file using the ftp_delete() function and close the connection using the ftp_close() function.

Error handling in ftp_delete()

It's important to handle errors properly when using the ftp_delete() function. If the function returns false, it means that the file couldn't be deleted for some reason. Here's an example of how to handle errors:

<?php

if (ftp_delete($conn, '/path/to/file.txt') === false) {
    echo "Failed to delete the file.\n";
} else {
    echo "File deleted successfully.\n";
}

In this example, we check the return value of the ftp_delete() function. If it's false, we display an error message; otherwise, we display a success message.
