将foreach循环包装到div中不起作用[重复]

已采纳

This question already has an answer here:

function news($newsarray) {
    $str='';

        '<div>foreach($newsarray as $value) 
        {
            $str.="<h3>{$value['title']}</h3>";
            $str.="<h4>{$value['content']}</h4>";
        }</div>'

    return $str;
    }
    echo news($newsarray);

I want to wrap it up the foreach loop into div, but it doesn't work, I know it is something with the escaping but I'm new in programming and I have hard times with the documentation. I've asked a similar question earlier, but I'm really confused, sorry for asking again.

on the localhost it says

Parse error: syntax error, unexpected title (T_STRING) in C:\xampp\htdocs ews ews.php on line 17

</div>

    Try this:

    function news($newsarray) { 
       $str='<div>';
    
       foreach($newsarray as $value) 
       {
           $str.="<h3>{$value['title']}</h3>";
           $str.="<h4>{$value['content']}</h4>";
       }
       $str.='</div>';
    
    return $str;
    }
    echo news($newsarray);

    Seems like you have your code placed in the string variable as well. Maybe this is what you were trying to do:

    function news($newsarray) { 
        $str='<div>';
    
        foreach($newsarray as $value) {
            $str .= "<h3>{$value['title']}</h3>";
            $str .= "<h4>{$value['content']}</h4>";
        }
    
        $str .= '</div>';
    
        return $str;
    } 
    
    echo news($newsarray);
