[img tag] [do while] My code cannot run correctly

hilda

Hi, I am a newbie to php.

I would like to make a php page to show 5 identical image in a row. As following:

But my code doesn't work

<?
$ImageNumber=5;
do{
	--$ImageNumber;
	echo "<img src="Image.png" width:"30px";>"
} while ($ImageNumber<=0);
?>

Thanks for any advice!

As far as the line that echoes out the img tag, you have several problems:
1. If you are going to wrap a string literal in double quotes, then any literal double quotes within it must be escaped with a back-slash.
2. Looks like you want a style attribute for the width?
3. You need a semi-colon that at the end of the line.

echo "<img src=\"Image.png\" style=\"width:30px;\">";

Alternatively, just use one type of quote to delimit the string literal and the other for literal quotes within the string:

echo "<img src='Image.png' style='width:30px;'>";

Or in this case, since you aren't really using any PHP functionality in that string, just exit out of PHP mode (and also fix your comparison logic!):

<?php
$ImageNumber=5;
do{
    --$ImageNumber;
?>
<img src="Image.png" style="width:30px;">"
<?php
} while ($ImageNumber>=0);
?>

(I strongly recommend the use of the full <?php tag, as short_open_tags may not always be enabled, and it avoids conflict with "<?xml" tags.)
