Re: [PHP] Heredocs, print_r() and newline "\n" and fnmatch() -curious failures ...
Thanks for the response - I found the answer to Q1 - the problem of formatting newlines - I was running the code outputting to browser - and got lazy on some - just pasting the PHP manual examples code directly, without bracketing with HTML tags such as ... etc. Of course that won't produce the formatting I was expecting and as shown in the manual. What confused me? - some example code includes the HTML tags and produce formatted output! So, I feel really stupid about that one. Perhaps there is a PHP manual update project in here somewhere to normalize the examples code so they can be run to get the output as printed. --- Q2 re the undefined function - fnmatch() - still needs an explanation. I need to get PHP's fnmatch() function, Xdebug, and iMagick's readImage() function working in the same setup. Using Xammplite_Win_32_1.7.1, PHP ver 5.2.9 reports fnmatch() is not a defined function and I haven't been able to get Xdebug functioning on this setup. readImage() works just fine. Using Xammp_Win_32_1.7.3, PHP ver 5.3.1 fnmatch() is defined and Xdebug works 'out of the box' but Apache crashes when iMagick readImage() is called. I think I should communicate this to the extension author. Will post here if I get a result. Thanks again, Peter.

If you've got xdebug installed, var_dump will provide a nicer output (including line-breaks). However, by far the easiest way to check if you're actually getting linebreaks in your output is checking the source. If you're suddenly experiencing a change in output, then some of your environment variables have changed - hard to say which one without knowing more about your system, but you must obviously have changed/updated something for this to happen.

Re: [PHP] Heredocs, print_r() and newline "\n" and fnmatch() - curious failures ...
As far as I know, you wont get any line breaks.
I would suggest putting the results into tags to preserve
formatting.
whenever I do a print_r(), i also encapsulate it within a
tag so it is readable.
on another note, when I use variables within double quotes "" (or even
the heredoc (but i use smarty templates instead)), I always wrap them in
curly braces {} as that is "suggested" (and I personally think should be
required).

[PHP] Heredocs, print_r() and newline "\n" and fnmatch() - curious failures ...
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 ...
-
foo = 'Foo';
$this->bar = array('Bar1', 'Bar2', 'Bar3');
}
}
$foo = new foo();
$name = 'MyName';
echo <bar[1]}.
This should print a capital 'A': \x41
EOT;
// again no newlines on direct heredoc echo ...
echo <<
-
Here's the output: - the line breaks are non-existent - here, of course
the wrapping is imposed by the mail client editor, but in the browser it
just it all just runs together .. most curious, very frustrating.
