Arrays are often used in smarty. section or foreach is used to traverse arrays cyclically. how can we determine whether an array is empty? two methods are described below Arrays are often used in smarty. section or foreach is used to traverse arrays cyclically. how can we determine whether an array is empty? two methods are described below:

1. use count to obtain the number of subscripts of the array.

In the following example, if $ array is null, no data is output.

Reference content is as follows:
{If $ array | @ count neq 0}
......
{/If}

2. directly judge
