PHP File Handling
File handling is used to open and process a file for different tasks.
PHP Manipulating Files
PHP has several functions for creating, reading, uploading, and editing files.
PHP readfile() Function
The readfile() function reads a file and writes it to the output buffer.
Assume we have a text file called "webdictionary.txt", stored on the server, that looks like this:
CSS = Cascading Style Sheets
HTML = Hyper Text Markup Language
PHP = PHP Hypertext Preprocessor
SQL = Structured Query Language
SVG = Scalable Vector Graphics
XML = EXtensible Markup Language
