This example describes how to use the smarty template to determine whether an array is null. Share it with you for your reference. The details are as follows:

Here we mainly introduce two methods:

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

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

{If $ array | @ count neq 0} // array is empty {/if}

2. Direct judgment

{If $ array neq ""} // array is empty {/if}

I hope this article will help you design php programs based on the smarty template.
