Subject: Adding a way to retreive compile options at runtime

Hello everybody,

Today we talked about a way to detect --with-curlwrappers at runtime.
It is nowadays not possible easilly.

Then , I remembered I once proposed to add a new function that could return
every ./configure options used to compile the runtime PHP the code is
beeing run on.

We already have "php-config --configure-options", but that needs to exist
and that needs an exec() call.
We also already have phpinfo() which returns that, but not in a very fancy
way (we need to preg_ the output which is ugly and not very simple).

Today, Seldaek proposed what I think is a cool way to solve this problem :
add a new parameter to phpinfo() function, which could return in an array
what it usually directly print throught the SAPI print() function (HTMLing
the output when needed).

The use case would be :

<?php
$output = phpinfo(INFO_GENERAL, true);

var_dump($output);
/* something like
['Debug Build' =>'no', 'Thread Safety'=>'yes', 'Configure
Command'=>['--enable-foo', '--with-config-file-scan-dir'=>'/etc'
]]


As you can see, it is rather simple but would need some work as it is
better for the "Configure Command" to return an array with the options
instead of a big string ; easier to parse.

Thoughts ?
