variable variables... not just $$a

[epimeth]

I had assumed this should work, but it doesn't. am I doing something wrong or do is the only way to do this to use the eval() statement?

<?php

$type = 'today';
$todayimage = '/images/today.gif';

echo '<img src="'. ${$type}image .'" />';

?>

obviously, $type and $todayimage are defined elsewhere... and there are more $type possibilites and a $typeimage for each $type...

so do I have to do eval('echo $type,"image"'); ?

lol... that eval won't work... I'll figure out the right one now...

Try escaping the quotes with \"

[epimeth]

got it...

eval ("echo '<td valign=\"top\"><img src=\"', $".$type."image['src'], '\" height=\"', $".$type."image['y'], '\" width=\"', $".$type."image['x'], '\" /></td>';");

but still doesn't answer why ${$type}image didn't work!

A matter of needing some way to discern where the variable name ends? image would need to be a string for it to be concatentated with the contents of $type

${$type.'image'}
