    #include <vector>

    void Split(const charpszStrIn, const char delimiterstd::vector<char*>* vecStrOut)
    {
        
    int        nStrInLen
        
    int        nFoundPos;
        
        
    char*    pszTmp;
        
    int        nTmpLen;

        
    nStrInLen    strlen(pszStrIn);
        
    nFoundPos   0;

        for (
    int i=0i<nStrInLen; )
        {
            
    nFoundPos 0;

            
    // ----------------------------------------
            // Find Delimiter
            // ----------------------------------------
            
    for (int ii=iii<nStrInLenii++)
            {
                if ( (
    pszStrIn[ii] == delimiter) )
                {
                    
    nFoundPos ii;
                    break;
                }
            }

            if (
    nFoundPos 1)
                
    nFoundPos nStrInLen;


            
    // ----------------------------------------
            // push vector
            // ----------------------------------------
            
    nTmpLen = (nFoundPos-i)+1;
            
    pszTmp = new char[nTmpLen];

            
    memset(pszTmp0nTmpLen);
            
    memcpy(pszTmp, (char*)(pszStrIn+i), nTmpLen-1);
            
    vecStrOut->push_back(pszTmp);

            
    += ((nFoundPos-i) + 1);
        }
    }

    void FreeSplit(std::vector<char*>* vecStr)
    {
        for (
    std::vector<char*>::iterator it vecStr->begin(); 
            
    it!=vecStr->end(); ++it) {
            
    delete *it;
        }

    Usage.
    PHP Code:
        std::vector<char*> str;

        
    Split("Hello, how are you ?"' ', &str);

        for (
    u_int i=0i<str.size(); i++)
            
    printf("%s\n"str[i]);

        
    FreeSplit(&str); 
    Result.
