This article mainly introduces the method of using loop tag in phpcms, which is very detailed and has certain reference value. Friends who are interested must finish it!

In phpcms, loop is widely used, 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 differences are as follows:

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

Form 2 in the $data array has a key value, which is this form of "A1 = > aa", "a2 = > bb", "A3 = > cc". A1 Magi a2 data A3 is called the key value of $data. If we want to take out the variable value of A1, that is, aa, we can use $data [A1], we can get aa, in the same way $data [a2], that is, bb.

So in PHPCMS, form one:

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

Form two:

In the loop $an is A1, a2, a3 aa,bb,cc in the above example.

Examples are as follows:

Example 1:

There are three values "aa", "bb" and "cc" in the $data array, so:

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

Aa,bb,cc will be output.

Example 2:

There are three "A1 = > aa", "a2 = > bb" and "A3 = > cc" with key values in the $data array, so

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

Output a1-aa | a2-bb | a3-cc |.
