Code:

new Chat[4][128] =
{
    "hi",
    "how are you?",
    "hello",
    "ajsdknjsd"
};

Code:

new i,j;

for(i=0;i<4,i++)
{
  for(j=0;j<128,j++)
  {
    if(!strcmp(cmdtext,Chat[i][j],false) return SendClientMessage(playerid,0xffffffaa,"You are answer wasn't understood by me Sir.");
  
    //then your script here

  }
}

I am not sure coz I learned C++ and maybe it might work. Try something like that.
