# Reading Files
 
PHP reads file contents using functions like `file_get_contents()` for reading the entire file as a string, and `fopen()` with `fread()` for reading in chunks. `file()` reads a file into an array of lines. File reading is used for logs, configuration files, uploads, and data imports.
