After using php for a while and coming back to c++, I find myself missing the explode function a great deal, along with the corresponding implode function. Does anyone know if the string class in c++ has the equivalent? I googled for a while but couldn't find any document for explode. Or perhaps someone has written one themselves? If anyone has any information it would be greatly appreciated.

There's a good deal of them out there, search for tokenize, not explode.

Actually, just for kicks I searched for C++ explode, and the first link was:
http://www.emuboards.com/invision/lofiversion/index.php/t19541.html
which contains:

vector<string> explode(string s, string e) {
 vector<string> ret;
 int iPos = s.find(e, 0);
 int iPit = e.length();
 while(iPos>-1) {
   if(iPos!=0)
     ret.push_back(s.substr(0,iPos));
   s.erase(0,iPos+iPit);   // poistetaan stringistä ylimääräiset scheißet
   iPos = s.find(e, 0);    // haetaan erottimen sijainti
 } // end while
 if(s!="")
   ret.push_back(s);
 return ret;
}

If that doesn't work as you'd like it, try looking through the results for C++ tokenize, as that's what it'll be called (because of C).

If you can get a good compiler that can handle it, I think you can use two codebasesin making a program. If nothing else works, you might could try mixing PHP and C++...
