How to properly nest PHP in HTML

If you want to nest PHP code in HTML, there is usually no problem. But in a conditional statement you also need a conditional statement, how do you want to write it?

Such as:

  
                               
下载列表
                
  
                       ....    
  
                                                              
  
   

As above, in determining whether a cookie exists, it is also necessary to determine whether $list exists. But it's a mistake to write.

Don't know what the solution is?

Http://www.php1.cn/article/7279.html look at this first, MO-Hurry.

If you don't understand, write the entire paragraph of the PHP statement and then use ECHO to enter the HTML tag tag is too faint.
or use a template.

Landlord can look at PHP alternative syntax specification: http://php.net/manual/zh/control-structures.alternative-syntax.php

I ran no error, ah, what you reported the wrong stickers out.

If the substitution syntax is not good, change back to the basic syntax

                   ....    
  
                                                      
  
   

But this really does not faint ....

Like your judgment of a cookie, the individual thinks it should be put in 逻辑层 , and should not be left behind 显示层 . So the code structure will be very bad, to the back of the poor maintenance.
