PHP连接echo中的图像链接

Question

I want to echo the image such that the variables $CatSelected will be the folder of the images and $char and $i are part of the img names : e.g

echo "<img src =\"Images/product/".$CatSelected."/".$char$i."s0.jpg"\>";

Answer 1

 echo "<img src =\"Images/product/".$CatSelected."/".$char.$i."s0.jpg\"\>";
                                                          ^          ^

1) You forgot to concatenate $char and $i.

2) You forgot to escape the double quotes.
