FW: [PHP] Constants and "Here Document" Interpolation

Actually I did try it and couldn't think of a way to work around the matter. Thanks for the suggestion. -----Original Message----- From: Ernest E Vogelsinger [mailto:ernest@vogelsinger.at] Sent: Saturday, March 01, 2003 12:56 PM To: Daniel R.

The answer: no, you cannot have a constant within a string, be it heredoc or quoted. A constant must always reside on "native code level". However you can easily concatenate strings and heredocs - both of the examples below work correctly: define('A_CONSTANT', 1); $text1 = <<<EOT This heredoc text contains the constant A_CONSTANT ( EOT . A_CONSTANT . <<< EOT ) outside the heredoc construct... EOT; $text2 = "This quoted text contains the constant A_CONSTANT (" . A_CONSTANT . ") outside the string quotes..."; echo "$text1<br />$text2"; Output: This heredoc text contains the constant A_CONSTANT (1) outside the heredoc construct... This quoted text contains the constant A_CONSTANT (1) outside the string quotes... -- >O Ernest E. Vogelsinger (\) ICQ #13394035 ^ http://www.vogelsinger.at/
