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.
