Smarty foreach Detailed description
For the knowledge of Smarty foreach, here is a detailed explanation of its function and usage.
Smarty {foreach} is used to iterate through an associative array like iterating over a numeric index array, unlike
{Foreach}, {foreachelse}
{Foreach} is used to cyclically access an associated array like a digital index array. It is different from the {Section} That can only access the numeric index array, the syntax of {foreach} is much simpler than that of
The use of foreach is often used in PHP, and if you use foreach, you must use an array. So in this article, we talk about the array, and we're talking about foreach.
foreach has two kinds of syntax:
First: Iterate over the given array statement
The For loop is the most complex loop structure in PHP. Its behavior is similar to the C language. The syntax for the For loop is:
for (EXPR1; expr2; expr3) statement
The first expression (EXPR1) is evaluated unconditionally before the start of the

Comparison of foreach and while loops in php. Foreach and while are both loops in php, so what is their difference between foreach and while loops, and that performance will be better, next, I will introduce the differences between foreach and while
The foreach basic syntax is as follows:
FOREACH ($array _variable as $value)
{
[Code to execute]
}
Or
FOREACH ($array _variable as $key => $value)
{
[Code to execute]
}
In both cases, multiple [code executions] will be executed equal to the number
