increment in HTML

[Anon]

hi

i was trying to use PHP to display images from 1 to 5. But it didn't work.

$root is my root directory
$image is assigned the value of 1

here is my codes:
print "<img src=$root/$image.jpg>";

print "<img src=$root/$image++.jpg>";

the first line shows me the correct image. The second line doesn't. The source of HTML displays <img src=myurl.com/1++.jpg> (i want it to be <img src=myurl.com/2.jpg>). I know I can do it manually by adding $image=image+1; between these codes. Are there any other ways to do that? If yes, please tell me how.

Thank You!

Try using a for loop (where i is the image)
for ($i=1;$i<5;i++)
{
print "<img src=$root/$i.jpg>";
}

You need to concatenate your print statemnet
print "<img src=".$root."/".$image++.".jpg>";

In PHP, quoted variables are printed directly, they are not interpreted or evaluated.
