This is an expression to count all the players on the server.

Also, it is:

pawn Code:

for(new i = 0; i < MAX_PLAYERS; i++)
{
// action
}

This is a for loop.
There are while and do while loop's as well.

What it does is, it first initialize i with 0 and check for condition(in your case i must not be equal to MAX_PLAYERS with is 500).

If condition is true, the code is executed.

Example

pawn Code:

for(new i=0;i<10;++i) printf("%d,"i);

In first eteration i = 0 which is less than 0 , so printf is executed and value of i is increased by 1.
This goes on till i is less than 10 .
In 10th eteration i will be 10. So loop stops

Code:

//result
0123456789

pawn Code:

for(i=0,j=10;j>15;++j,++i) {}

This loop is executed only 5 times as at 6th time j will be 15, which is not less than 15.
