This document discusses PHP file handling functions. It explains how to open, read, write, append, close and delete files using PHP functions like fopen(), fread(), fwrite(), fclose() and unlink(). It provides code examples to open a file in write mode, read the contents of a file, write data to a file, append data to a file without overwriting existing contents, close an open file stream, and delete a file. PHP file handling allows dynamically managing files through these basic file operations.
