I am creating a simple PHP module with PHP-CPP library.
I make this to limit process per IP address per php script file. I have found a solution for everything I needed, except 1 thing : I cant stop the script cleanly.
If you look in the script it have exit(0); .. If I use for example Php::echo(); for writing some headers and HTML, that result doesn't get returned to the web browser (nor telnet).
Do you know a method to echo some headers and body then kill the script without executing the final script ?
Thank you very much !
#include <phpcpp.h>
#include <iostream>
#include <fstream>
#include <stdio.h>
extern "C" {
PHPCPP_EXPORT void *get_module() {
static Php::Extension extension("dosguard", "0.9");
extension.onShutdown([]() {
system("rm -r /dev/shm/dosguard-*");
});
extension.onRequest([]() {
std::string inode = Php::call("fileinode", Php::SERVER["SCRIPT_FILENAME"]);
std::string ip = Php::SERVER["REMOTE_ADDR"];
int time = Php::call("time");
std::string shm = "/dev/shm/dosguard-"+inode+"@"+ip+".time";
int saved = Php::call("file_get_contents", shm);
if(saved >= time) {
//////////////////////////////////////////
exit(0);
//////////////////////////////////////////
} else {
if(saved == NULL) {
saved = time;
}
else {
saved = time + 1;
}
Php::call("file_put_contents", shm, saved);
}
});
return extension;
}
}
