Imagine that. Your MAX_PLAYERS define variabile it's setted to 500. You have to check each player to do something for it. To check if a player it's on server, you must use the IsPlayerConnected function.
Let's say you have 4 players connected:
Player ID 0: Jack
Player ID 1: Dean
Player ID 2: Paul
Player ID 3: Sam
The rest of slots are empty slot. So, to don't check each player in 500 lines, like:

PHP код:

if(IsPlayerConnected(0)) /* Do code */
if(IsPlayerConnected(1)) /* Do code */
if(IsPlayerConnected(2)) /* Do code */
if(IsPlayerConnected(3)) /* Do code */
if(IsPlayerConnected(4)) /* Do code */
/*..................................*/
if(IsPlayerConnected(99)) /* Do code */
if(IsPlayerConnected(100)) /* Do code */
/*..................................*/
if(IsPlayerConnected(300)) /* Do code */
if(IsPlayerConnected(301)) /* Do code */
/*..................................*/
if(IsPlayerConnected(499)) /* Do code */
if(IsPlayerConnected(500)) /* Do code */ 


You can do that with for loop:

PHP код:

for(new i = 0; i < MAX_PLAYERS; i++)
    if(IsPlayerConnected(i))
        /* Do code */ 


First, he checks the first index, = 0. After that, the for loop checks the next index, by incrementing variabile i to 1 ( i++ = (i = i + 1) = (i += 1) ). When i = MAX_PLAYERS, the for loop is break.
