How to use php statements in dedecms? (user's guidance)

In DEDECMS, if you use the php statement, the {dede:php} tag can be used. The simplest input is:

{dede:php}
　　$numA = 1;
　　$numB = 2;
　　echo $numA + $numB;
{/dede:php}

From the above statement It can be seen that the dede:php tag can be used in the same way in PHP. The above statement is written as follows in PHP:

<?
$numA=1;
$numB=2;
echo $numA+$numB;
?>

Doesn’t it look similar? Take another look and have an if else condition. I won’t write the judgment

[field:global runphp='yes' name=autoindex] 
$a="<SPAN class=&#39;num active&#39;>"; 
$b="</SPAN>"; 
$c="<(www.jb51.net)SPAN class=&#39;num&#39;>"; 
if (@me > 3) @me = $c.@me.$b; 
else @me = $a.@me.$b; 
[/field:global]

How to write this in php. Next we have to look at the use of dede php tags in combination with sql tags.

Combined with SQL query to output a single piece of content

{dede:php}
$row = $dsql->GetOne('select id,typename from dede_arctype where id=2');
print_r($row);
{/dede:php}

The output content is:

Array
(
[id] => 2
[typename] => 问答
)
