php—Smarty-5 （22）

Continued from the previous article

11. section, sectionelse Section is a loop structure statement, mainly used to traverse arrays

Grammar:

{section name=name loop=loop array (number of times) start=start(0) step=step(1) max=maximum number of loops}
{sectionelse}

{/section}

The difference between Foreach and section:

Foreach refers to traversing an array directly

Section is a loop statement, and its number of loops is determined by the number of arrays

Section has more options when traversing arrays

l section’s built-in variables

            {$smarty.section.name.index_prev} Last loop index

                                                                                                                                                    {$smarty.section.name.index_next} The next cycle index

{$smarty.section.name.iteration} Loop index starts from 1

                                                                                                                                                                                                                                                                                         out out to be Ar {$ SMARTY.SECTION.NAME.TOTOTAL} Total number of cycles
