File Handling in PHP

 File Handling in PHP

PHP can be used to read, write, and manipulate files on the server. File handling functions are used to open, read, write, and close files.

Example:

php

// write to a file

$file = fopen("example.txt", "w");

$txt = "Hello World";

fwrite($file, $txt);

fclose($file);

// read from a file

$file = fopen("example.txt", "r");

echo fread($file, filesize("example.txt"));

fclose($file);
