如何限制PHP数组中返回的结果

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?

您将偏移量和限制值放在array_reverse方法参数而不是array_slice参数中。

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

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