PHP File Handling

PHP provides a rich set of functions for file handling. You can create, read, write, and manipulate files on the server using these functions.

Common File Handling Functions

  • fopen(): Opens a file.
  • fread(): Reads from a file.
  • fwrite(): Writes to a file.
  • fclose(): Closes an open file.
  • file_get_contents(): Reads the entire file into a string.
  • file_put_contents(): Writes data to a file.

Example of File Handling

<?php
$file = 'example.txt';

// Create and write to a file
file_put_contents($file, 'Hello, World!');

// Read the file
$content = file_get_contents($file);
echo $content;
?>

Explanation: This example creates a file named example.txt, writes "Hello, World!" to it, and then reads and displays the content of the file.
