Working with Files in PHP

Working with Files in PHP

Files in PHP are used to store data and can be used to store text, images, and other types of data. PHP provides a set of functions for working with files, such as opening, reading, writing, and closing files.

For example, a simple function that reads the contents of a file:

function readFile($file) {
    $contents = file_get_contents($file);
    return $contents;

In this example, the function readFile() is declared and takes a parameter $file, which is the path to the file to be read. The function uses the file_get_contents() function to read the contents of the file into a string, and then returns the contents. The output of this function when called with the parameter “data.txt” would be the contents of the file data.txt.
