Error log says Premature end of script headers: php5.cgi at the time of the server error.

The echo vardump(... line produces…

array(10) { [0]=>  string(43) "textpattern/publish.php:973 trigger_error()" [1]=>  string(13) "processTags()" [2]=>  string(51) "textpattern/publish.php:922 preg_replace_callback()" [3]=>  string(44) "textpattern/lib/txplib_misc.php:1412 parse()" [4]=>  string(40) "textpattern/publish.php:704 parse_form()" [5]=>  string(40) "textpattern/publish.php:808 doArticles()" [6]=>  string(43) "textpattern/publish.php:509 parseArticles()" [7]=>  string(37) "textpattern/publish.php:963 article()" [8]=>  string(13) "processTags()" [9]=>  string(51) "textpattern/publish.php:922 preg_replace_callback()" }

Weird, looks like I can use the return value as a direct argument to vardump() but not join().

I can confirm this bug, and also the healing powers of Steve’s workaround

$callers = get_caller(10);
print "\n<pre style=\"padding-left: 2em;\" class=\"backtrace\"><code>".escape_output( join( "\n", $callers ) )."</code></pre>";

Apache/1.3.33 (Debian GNU/Linux) FrontPage/5.0.2.2623 mod_ssl/2.8.10 OpenSSL/0.9.7 PHP/5.2.3

EDIT: Bug does not occur with PHP 4.4.7, does occur with PHP 5.2.3 on two distinct hosts.

One runs as CGI, the other runs as an Apache module.

Does this also occur in PHP 5.2.4 or 5.2.5?
I mean, if we can’t rely on join() working properly when it is fed a simple array, we might as well dump PHP and switch to a different language.

Sorry, I don’t have access to anything higher than 5.2.3 without pulling the source code and learning how to build it myself. As it’s just about midnight here I don’t intend going through that learning curve today :)

I feel the pain there too. Perhaps the news isn’t so bad. <g> It seems the problem is limited to cases where the second is an array directly returned by a function. Thankfully there are just a few of these cases in the source.
