File handling in PHP

PHP file handling refers to the ability of the PHP programming language to manipulate files on a server or computer. With PHP file handling, developers can create, read, write, and delete files on the server.

Some common file handling functions in PHP include fopen() to open a file, fread() to read from a file, fwrite() to write to a file, fclose() to close a file, and unlink() to delete a file.

PHP also supports file uploads, which is useful for allowing users to upload files to a website. With PHP’s file handling capabilities, developers can create powerful applications that involve reading and writing files, managing file systems, and processing file data.
