Using Constants in PHP

[Anon]

When I define a constant, like:

define("imageUrl","http://url/images/");

How can I access it from within an echo(" "); statement?

For example, i would like to be able to do:

echo("<img src=\"imageUrl/$filename.jpg\">");

but it just prints out imageUrl instead of the constant's value.

if I do :

$imageUrl = imageUrl;

I can then use $imageUrl in the echo and it works as expected. I just dont wanna have to do this everytime I want to use a constant, it seems awfully redundant.

Thanks!

If you want to use your constant from an echo() or print(), you have to do it outside the quotes:

<?php
define ("MYCONST", "This is my constant");
echo MYCONST; // prints "This is my constant"
echo "MYCONST; // prints "MYCONST"
?>

If you want to print it inside some other text, you have to use concatenation:

<?php
echo "My constant is: ". MYCONST;
?>
