From: animaz on 23 Sep 2010 15:47 This code is 95% cut and paste from the PHP manual examples - the Types/Strings/Heredocs section and the Filesystem/fnmatch pages. There are actually two questions here - I have combined the code into one test file ... the strings in the code contain the questions .. at the end I have inserted the output I get from the code - identical in Firefox and IE8 (so it's not browser related), and on my desktop as well as my laptop (so it's not a machine quirk). The setup is Xammplite Win32-1.7.1 with PHP 5.2.9 and Apache 2.2.11 on both WinXP-SP3 installs. I tried Xammp Win32-1.7.3 with the same results. Then I tried installing Apache and PHP and MySQL individually, and got the same ... Aside from the issue here, I also was unable to get imagick and xdebug running on the same installation - it was one or the other. imagick's readfile() caused Apache to baulk on PHP5.3.3, so I returned to a fresh Xammplite setup. Same results. I have spent many hours with this - I would appreciate some insight .. Question 1 : how to get the newline functioning ....? even print_r() output is not 'newlined' as it should be. Also note the \n is missing between the " " in the output text of the second test! Question 2 : fnmatch() is an internal function (ie built in to PHP, yet get_defined_functions() does not find it. Perhaps there are others also missing, I haven't done a check - could it be a compile error in Xammplite's PHP binaries? ----------------------------------------------------------------- heredoctest.php = the // comments are not in the actual file ... ----------------------------------------------------------------- <?php $str = <<<EOD Example of string spanning multiple lines using heredoc syntax.
