I always wanted to know how to use the explode() function from PHP in C++. I have finally found a way. This is just another part of my server. So, please no flaming because it is useless by itself.

Heres the code:

CODE

#include <cstdlib>
#include <iostream>
#include <vector>
#include <string>
#include <sstream>

using namespace std;

int main()
{
string str = "000011222 X 2502";
cout << str;
cout << "\n";
string buf;
stringstream ss(str);m

vector<string> tokens;

while (ss >> buf)

tokens.push_back(buf);

cout<< "Messages handle is:";
cout<<tokens[0]<<" ";
cout<< "\n";

cout<< "Messages variable is:";
cout<<tokens[1]<<" ";
cout<< "\n";

cout<<"Messages variable update is:";
cout<<tokens[2]<<" ";
cout<<"\n";

cin.get();

}

Cheers, Daniel

Basically if I have a string from a file that contains "Stenny|password|25.07.81" Then I can put that through Explode (like so):

CODE

string = "Stenny|password|25.07.81";

explode('string', '|');

And itll output an array with 3 elements. Each element with be split up by a |. So element 1 will be Stenny.

And em, I don't understand the point of this(also don't know how it works, could you explain?) at least, how do I use it?

Cool, kind of like a strtok.

BG, you would whack a string (blah|black|sheep) in there and a char like '|' as he shows. Once you ran it you would get:

string[0] = blah
string[1] = black
string[2] = sheep

It just splits your string up when it finds the char you put in as the '|'.

EDIT[]

The strtok I'm talking about:

CODE

strtok(const string[], &index)
{
new length = strlen(string);
while ((index < length) && (string[index] <= ' '))
{
index++;
}
new offset = index;
new result[20];
while ((index < length) && (string[index] > ' ') && ((index - offset) < (sizeof(result) - 1)))
{
result[index - offset] = string[index];
index++;
}
result[index - offset] = EOS;
return result;
}

Pawn version ^^^. I don't do c++ so I aint got a clue what the would look like in c++, I'll leave you to think about that one...

No no no ... that's strtok , not split

Split - Pawn Version

CODE

public split(const strsrc[], strdest[][], delimiter)
{
new i, li;
new aNum;
new len;
while(i <= strlen(strsrc))
{
if(strsrc[i] == delimiter || i == strlen(strsrc))
{
len = strmid(strdest[aNum], strsrc, li, i, 128);
strdest[aNum][len] = 0;
li = i+1;
aNum++;
}
i++;
}
return 1;
}
