在PHP中连接变量

Question

I would like to concatenate 2 variables or a string and a variable with the following code,

$dir = '<img src="image_folder/"';

if ($query_Result >0) 
{
        while($row = mysqli_fetch_assoc($result)) 
       {
            echo $dir.$row['image_link'].'>';

It only echos the src path and not the $row variable. I have tried echoing out the string

'<img src="image_folder/".$row['image_link'].'>'

but nothing seems to work.

Can someone suggest a way round this?

if ($query_Result >0) 
{
    while($row = mysqli_fetch_assoc($result)) {
         echo  "<img src='image_folder/".$row['image_link']."'>";
    }
}
