Read Files In PHP

PHP provides various functions to read data from a file. There are different functions that allow you to read all file data, read data line by line and read data character by character.

This function returns the number of bytes read on success, or FALSE and an error on failure. You can hide the error output by adding an "@" in front of the function name.
