Check if a string exists in an array. - ChristolisTV - 05.05.2017

Hello! I'm making a server but I have a problem. How can I check if a string (inputtext) exists in an array? I have tried this but it's not working:

PHP код:
new cityWords[][] = { //Beta
    "Shiopross City",
    "Cuacaster City",
    "Dine City",
    "Looton City"
};
if(dialogid == DIALOG_QUIZ_2)
{
    if(response)
    {
        for(new i; i < sizeof(cityWords); i++)
        {
            if(!strcmp(inputtext, cityWords[i], true))
            {
                SendClientMessage(playerid, -1, "You found one of the hidden cities!");
                GivePlayerMoney(playerid, 10000);
                break;
            }
            else if(i == 5)
            {
                SendClientMessage(playerid, -1, "This hidden city doesn't exist. Try again!");
                ShowPlayerDialog(playerid, DIALOG_QUIZ_2, DIALOG_STYLE_INPUT, "Hidden City", "Find one of the hidden cities and win a prize!", "OK", "Cancel");
                break;
            }
        }
    }
    return 1;
}

You didn't mention what not working.Although taking a quick glance at your code i saw this in the loop.
PHP код:
else if(i == 5) 
            { 
                SendClientMessage(playerid, -1, "This hidden city doesn't exist. Try again!"); 
                ShowPlayerDialog(playerid, DIALOG_QUIZ_2, DIALOG_STYLE_INPUT, "Hidden City", "Find one of the hidden cities and win a prize!", "OK", "Cancel"); 
                break; 
            } 
if i becomes 5 it violate loop rule and the above part will not work.Put that statement outside the loop.

SyS is right. Anyway, the next code worked perfectly for me:
PHP код:
new g_Texts[3][6] = { /* 3 rows - 6 characters as max. per row */
    {"hi"},
    {"hello"},
    {"bye"}
};
new inputtext[6] = "hello";
new bool:found;
for(new x = 0; x < sizeof(g_Texts); x++)
{
    if(strcmp(inputtext, g_Texts[x], true) == 0)
    {
        found = true;
        SendClientMessage(playerid, -1, "You found one of the hidden cities!");
        break;
    }
}
if(!found)
{
    SendClientMessage(playerid, -1, "This hidden city doesn't exist. Try again!");
}
