Usage of smarty built-in function section, smarty built-in section

The example in this article describes the usage of smarty’s built-in function section. Share it with everyone for your reference. The specific analysis is as follows:

The foreach function can do everything that section can do, so foreach is generally used. Here we also explain the usage of section in detail. Section can only traverse index arrays, not associative arrays.

Example of outputting array key values ​​in reverse order:

Template file: temp.htm

Copy code The code is as follows:

{section name=foo loop=$name step=-1}
{$name[foo]}
{/section}

Parameter description:

name is the name of the section;
loop is the array variable of the loop;
step is the step size of the loop. If step=2, it means that only the values ​​with subscripts 0, 2, and 4 are looped. If step is a negative number, it means starting from the end.
Among them, name and loop are parameters that must be filled in.

I hope this article will be helpful to everyone’s PHP programming design.
