Dedecms {dede: php} label usage

The simplest input is as follows:

The code is as follows:	Copy code
{Dede: php} $ NumA = 1; $ NumB = 2; Echo $ numA + $ numB; {/Dede: php}

From the preceding statement, we can see that the dede: php tag can be used in the same way in php. The above statement is written in php as follows:

The code is as follows:	Copy code
<? $ NumA = 1; $ NumB = 2; Echo $ numA + $ numB; ?>

Does it look a lot like it? Let's look at another judgment using the if else condition.

The code is as follows:	Copy code
[Field: global runphp = 'yes' name = autoindex] $ A = "<SPAN class = 'Num activity'> "; $ B = "</SPAN> "; $ C = "<SPAN class = 'num'> "; If (@ me> 3) @ me = $ c. @ me. $ B; Else @ me = $ a. @ me. $ B; [/Field: global]

I will not write this code in php. Next we should look at the use of SQL labels combined with dede php labels.

Query and output single content in combination with SQL

The code is as follows:	Copy code
{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] => Q & )
