// Build a C99 extension for PHP int my_c_function(php_stream *stream) // Interact with PHP from C99 php_printf("Hello World!\n"); return 0;

In Shell scripting, the for loop is used to iterate over a sequence of commands. The basic syntax is:

Allows an attacker to read or execute files already present on the server.
