ID: 48177 User updated by: skds1433 at hotmail dot com Reported By: skds1433 at hotmail dot com Status: Bogus Bug Type: Unknown/Other Function Operating System: Windows Vista PHP Version: 5.2.9 New Comment: Thank you for the explanation, that makes a lot of sense now that you mention it. Sorry for wasting your time. Previous Comments: ------------------------------------------------------------------------ [2009-05-07 10:38:39] mattwil@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php eval() doesn't return anything but NULL unless a return statement is used in the eval'd code (wouldn't work in this case with inline HTML anyway, which gets echo'd immediately). You'd need to 1) echo "<pre>"; before the eval() call, 2) use eval('return "testing 123, a string, not HTML...";'), or 3) use output buffering, etc. ------------------------------------------------------------------------ [2009-05-07 10:22:38] skds1433 at hotmail dot com Changed category, from 'Output Control'.
