Fputs()

What is the fputs() Function?

The fputs() function is a built-in PHP function that writes a string to a file. This function is used to write data to files.

Here's the basic syntax of the fputs() function:

fputs(file, string, length);

Where file is the file pointer to write to, string is the string to write to the file, and length is the number of characters to write (optional).

How to Use the fputs() Function?

Using the fputs() function is straightforward. Here are the steps to follow:

1. Open the file you want to write to using the fopen() function in write-only mode.
2. Call the fputs() function, passing in the file pointer and the string you want to write to the file.
3. Repeat step 2 as needed for additional data to write to the file.
4. Close the file using the fclose() function.

Here's an example code snippet that demonstrates how to use the fputs() function:

<?php

$filename = 'myfile.txt';
$file = fopen($filename, 'w');
fputs($file, 'Hello, world!');
fclose($file);

In this example, we open the file myfile.txt using the fopen() function in write-only mode. We then write the string 'Hello, world!' to the file using the fputs() function before closing the file using the fclose() function.
