Differences between iteration and total in the foreach loop statement structure of the smarty template engine

In the foreach loop statement structure of the smarty template engineIterationAndTotalDifferences:

• Total displays the total number of times of loop execution.
• Iteration displaysCurrentNumber of cycles executed

Therefore, if you want to print the current serial number of each loop, you can use<{$ Smarty. foreach. foreachname. Iteration}>

For example:

<{Foreach from = $ Article item = Val key = key name = WHF}>

<{$ Smarty. foreach. WHF. Iteration}> --- <{$ key}> --> <{$ Val}> <br>

<{/Foreach}>

Current total cycle <{$ smarty. foreach. WHF. iteration-1}> times // note that the total number of cycles refers to the cycles in the array

// Including this loop

The result is similar:

1 --- id --> 1
2 --- article_id --> 1
3 --- uid --> 2
4 --- cat_id --> 2

The current cycle is 4 times in total

While

<{Foreach from = $ Article item = Val key = key name = WHF}>

<{$ Smarty. foreach. WHF. Total}> --- <{$ key}> --> <{$ Val}> <br>

<{/Foreach}>

Current total number of <{$ smarty. foreach. WHF. Total}> times

The result is similar:

4 --- id --> 1
4 --- article_id --> 1
4 --- uid --> 2
4 --- cat_id --> 2

The current cycle is 4 times in total
