Script to check Server Configs

I am writing a PHP script to test that tests to make sure the server has the proper configs set for our software. There are a couple I'm not 100% sure how to test.

1. Make sure the server has mysql installed and available without specifying any settings.
2. Make sure the curl library is available

I need some code that determines these. All it needs to do is say passed or failed.

Anyone got an example?

I was trying this that I found on PHP.net for the mysql but the shell_exec looks like a potential problem as it may be disabled on most servers.

function find_SQL_Version() {
   $output = shell_exec('mysql -V');
   preg_match('@[0-9]+\.[0-9]+\.[0-9]+@', $output, $version);
   return $version[0];

phpinfo isn't what I am looking for... this is an attempt to write a script that a non-programmer business owner can upload and know that their hosting is sufficient to use the scripts. So it has to be minimal.
PHP trows a warning when a command is not found (when software is not installed or working) with the message "unknown command"

You could use a error handler to take care of this (little primitive, but should work though):

$mysql_exists = true;
$curl_exists = true;

// error handler function
function myErrorHandler($errno, $errstr, $errfile, $errline) {
  if(substr_count($errstr,"unknown command")) {
    if(substr_count($errstr,"mysql_connect")) {
      $GLOBALS['mysql_exists'] = false;
      $GLOBALS['curl_exists'] = false;
  //echo "<b>WARNING</b> [$errno] $errstr<br />\n";
  return true;

// set to the user defined error handler
$old_error_handler = set_error_handler("myErrorHandler");

// just run the commands and let the error handler take care of the rest
$dbcon = mysql_connect();
$curl = curl_version();

// output results
echo $mysql_exists ? "mysql enabled<br />" : "mysql disabled<br />";
echo $curl_exists ? "curl enabled<br />" : "curl disabled<br />";
Im sorry, now I test this myself i see it is a different message: "Call to undefined function"
So change "unknown command" to this and it should work
