how to limit results that are returned in a PHP array

Question

I have this foreach loop in PHP where i loop through some array results:

foreach(array_reverse($output) as $row)

but i want to be able to limit the number of results so i can display the results on separate pages

i have tried using the function array_slice in PHP but had no luck, using the below code i just get no results returned

foreach(array_reverse(array_slice($output),0,5) as $row)

how can i limit the results returned in the array?

The closing bracket for array_slice is misplaced, array_slice takes 3 arguments. — MackieeE

Where is the information coming from? If it is a database you can limit the amount of rows in your query. — Crackertastic

Just for example, when running your code I get an error: array_slice() expects at least 2 parameters, 1 given in.... You can see it here: codepad.viper-7.com/g00O6N — Jonathan Kuhn

You put the offset and limit in the array_reverse method arguments instead of the array_slice arguments.

array array_reverse ( array $array [, bool $preserve_keys = false ] )

array array_slice ( array $array , int $offset [, int $length = NULL [, bool $preserve_keys = false ]] )
