php—Smarty-5 (22), phpsmarty-522
Continued from the previous article
11. section, sectionelse Section is a loop structure statement, mainly used to traverse arrays
Syntax:
{section name=name loop=loop array (number of times) start=start(0) step=step(1) max=maximum number of loops}
{sectionelse}
{/section}
Name: Name the section statement Required
Loop: Loop array required
Start: Start index Default value: 0
Step: step size Default value: 1
Max: Maximum number of loops Default value: Total length
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 selectivity in traversing arrays
l section’s built-in variables
{$smarty.section.name.index} loop index
{$smarty.section.name.index_prev} Last loop index
{$smarty.section.name.index_next} Next cycle index
{$smarty.section.name.iteration} Loop index starts from 1
{$smarty.section.name.first|last} These two values are true for the first and last execution
{$smarty.section.name.total} Total number of loops
12. strip Remove consecutive spaces before and after
Syntax:
{strip}
…
{/strip}

2. counter counter

Start: starting value
Skip: step size, default is 1
Print: Whether to output this time
