Displaying a list of all modules (extensions) installed

[DQ]

I just signed up for a web hosting service. They have PHP, but can't
tell me which modules (extensions) are installed.

Is there a function, or some other easy way, to show all modules
(extensions) that are installed? phpinfo() doesn't do this.

But of course it does! First, it shows you system information
(including configuration string), then, there's Configuration heading.
First table under Configuration is "PHP Core", the rest of the tables
contain data about extensions and their configuration. Something like
this:

bcmath
BCMath support enabled

calendar
Calendar support enabled

ctype
ctype functions enabled

curl
CURL support enabled
CURL Information libcurl/7.12.0 OpenSSL/0.9.6g zlib/1.1.3

Additionally, you can always check if an extension is present by
testing if functions defined in this extension are available. Example:
if (function_exists('imap_open')) {
echo "IMAP functions are available";
} else {
echo "IMAP functions are not available";
}

You could also call get_defined_functions() and see what extensions are
enabled from the list of functions that are available.

Cheers,

See http://fi.php.net/get-loaded-extensions/.

You're right! I couldn't see the forest for the trees. I was looking
for a list of key-value pairs. I didn't realize that the _headings_
were what I needed. Thanks.

Perfect! That's just what I needed.
