Whereas with a nested if the loop keeps on running until it's done, even if there's no more space to store data. So in this case you might write: PHP код: for(new i = 0, j = cache_get_row_count(); i < j && i < MAX_BUILDINGS; i ++)

Thank you! Could you explain what the difference of these conditions do and why they're important?

PHP код:

for(new i = 0; i < MAX_BUILDINGS; i ++) 


PHP код:

for(new i = 0, j = cache_get_row_count(); i < j && i < MAX_BUILDINGS; i ++) 


My guess is that if I run the first loop with MAX_BUILDINGS defined 50, the loop will go around 50 times?
However if I use the second one, the loop will run for as many rows that are returned by the query, so that if the query only returns 5 rows, the loop won't go around 45 times for nothing, which also works vice-versa with

PHP код:

&& i < MAX_BUILDINGS; 


which makes the loop stop, if the query should return 200 rows and I've defined the maximum number of buildings to be 50?
