How to use loop tag in phpcms

In phpcms, loops are used a lot, generally in two forms.

The form is as follows:

Form one:

{loop $data $a}
{$a}
{/loop}

Form two:

{loop $data $a $b}
{$a}---{$b}
{/loop}

The difference is as follows:

First of all, $data is an array. In the first form, the $data array is like this, "aa", "bb", "cc". In this form, To get the first value aa, we use this code $data[0], to get the second value we use $data[1], and so on.

Form 2, the $data array has an additional key value, which is in this form "a1=>aa", "a2=>bb", "a3=>cc", a1, a2 , a3 is called the key value of $data. If we want to take out the variable value with the key value a1, that is, aa, we can use $data[a1] to get aa. Similarly, $data[a2] also It’s just bb.

Then in PHPCMS, form 1:

In the loop, $a is $data[0], $data[1], $data[2], we directly write {$ a} can loop to get the value of $a.

Form 2:

In the loop, $a is a1, a2, a3 in the above example, and $b is aa, bb, cc in the above example.

The examples are as follows:

Example 1: There are three values ​​​​"aa", "bb", "cc" in the

$data array, then :

{loop $data $a}
{$a}
{/loop}

will output aa, bb, cc.

Example 2:

There are three key values ​​in the $data array: "a1=>aa", "a2=>bb", "a3=>cc", Then

{loop $data $a $b}
{$a}-{$b}|
{/loop}

will output a1-aa|a2-bb|a3-cc|.
