foreach from section

smarty的foreach能否遍历oop对象呢?
我知道{section}可以遍历oop对象,但是不懂的foreach是否也可以呢?

------解决方案--------------------
foreach 是除 section 之外处理循环的另一种方案(根据不同需要选择不同的方案).
foreach 用于处理简单数组(数组中的元素的类型一致),它的格式比 section 简单许多,缺点是只能处理简单数组.
foreach 必须和 /foreach 成对使用,且必须指定 from 和 item 属性.
name 属性可以任意指定(字母、数字和下划线的组合).
foreach 可以嵌套,但必须保证嵌套中的 foreach 名称唯一.
from 属性(通常是数组)决定循环的次数.
foreachelse 语句在 from 变量没有值的时候被执行.


------解决方案--------------------
当然是可以的
例如
{foreach from=$arrMembersList item=objMemberInfo}
{$objMemberInfo->iBookId}:{$objMemberInfo->strMembersName}
{/foreach}
------解决方案--------------------
foreach from=$array item=tt
$array[tt].

What is the difference between using foreach and iterator to delete elements when traversing Java ArrayList? What is the difference between using foreach and iterator to delete elements when traversing Java ArrayList? Apr 27, 2023 pm 03:40 PM

1. The difference between Iterator and foreach is the polymorphic difference (the bottom layer of foreach is Iterator) Iterator is an interface type, it does not care about the type of collection or array; both for and foreach need to know the type of collection first, even the type of elements in the collection; 1. Why is it said that the bottom layer of foreach is the code written by Iterator: Decompiled code: 2. The difference between remove in foreach and iterator. First, look at the Alibaba Java Development Manual, but no error will be reported in case 1, and an error will be reported in case 2 (java. util.ConcurrentModificationException) first

How to determine the number of foreach loop in php How to determine the number of foreach loop in php Jul 10, 2023 pm 02:18 PM

​The steps for PHP to determine the number of the foreach loop: 1. Create an array of "$fruits"; 2. Create a counter variable "$counter" with an initial value of 0; 3. Use "foreach" to loop through the array, and Increase the value of the counter variable in the loop body, and then output each element and their index; 4. Output the value of the counter variable outside the "foreach" loop to confirm which element the loop reaches.

PHP returns an array with key values ​​flipped PHP returns an array with key values ​​flipped Mar 21, 2024 pm 02:10 PM

This article will explain in detail how PHP returns an array after key value flipping. The editor thinks it is quite practical, so I share it with you as a reference. I hope you can gain something after reading this article. PHP Key Value Flip Array Key value flip is an operation on an array that swaps the keys and values ​​in the array to generate a new array with the original key as the value and the original value as the key. Implementation method In PHP, you can perform key-value flipping of an array through the following methods: array_flip() function: The array_flip() function is specially used for key-value flipping operations. It receives an array as argument and returns a new array with the keys and values ​​swapped. $original_array=[

PHP returns the current element in an array PHP returns the current element in an array Mar 21, 2024 pm 12:36 PM

This article will explain in detail about the current element in the array returned by PHP. The editor thinks it is very practical, so I share it with you as a reference. I hope you can gain something after reading this article. Get the current element in a PHP array PHP provides a variety of methods for accessing and manipulating arrays, including getting the current element in an array. The following introduces several commonly used techniques: 1. current() function The current() function returns the element currently pointed to by the internal pointer of the array. The pointer initially points to the first element of the array. Use the following syntax: $currentElement=current($array);2.key() function key() function returns the array internal pointer currently pointing to the element

What is the difference between foreach and for loop What is the difference between foreach and for loop Jan 05, 2023 pm 04:26 PM

Difference: 1. for loops through each data element through the index, while forEach loops through the data elements of the array through the JS underlying program; 2. for can terminate the execution of the loop through the break keyword, but forEach cannot; 3. for can control the execution of the loop by controlling the value of the loop variable, but forEach cannot; 4. for can call loop variables outside the loop, but forEach cannot call loop variables outside the loop; 5. The execution efficiency of for is higher than forEach.
