Question

[php]{{foreach from=$category_list item=v key=key}} <a href="shop-list.php?cat_id={{$key}}">{{$v}}<

{{foreach from=$category_list item=v key=key}}
<a href="shop-list.php?cat_id={{$key}}">{{$v}}</a>
{{/foreach}}
1.from=$category_list是哪的
2.item=v是什么意思代表什么
3.key=key
没明白的，最好有个例子详细说明

Answer 1

$category_list = "array";
foreach from=$category_list item=v key=key
相当好正于
foreach( array as $key=>$v)

array是要循环的数组变量
$key是循环中数组宏冲中一个元素的下标
$v是元素的值

$array["first"] = "one";
$array["second"] = "tow";
foreach($array as $key=>$v){
echo "key = ".$key;
echo "v = "友绝悔.$v;
}
第一遍输出
key = first
v = one
第二遍
key = second
v = tow

Answer 2

相当于 foreach ($category as $key=>$v) {...}

Answer 3

相厅岩当扮或御于团如 foreach ($category as $key=>$v) {...}
