EXAMPLES

       Example #1

	      curl_version(3) example

	       This example will check which features that's available in cURL build by using the 'features' bitmask returned by curl_version(3).

	      <?php
	      // Get curl version array
	      $version = curl_version();

	      // These are the bitfields that can be used
	      // to check for features in the curl build
	      $bitfields = Array(
			  'CURL_VERSION_IPV6',
			  'CURL_VERSION_KERBEROS4',
			  'CURL_VERSION_SSL',
			  'CURL_VERSION_LIBZ'
			  );

	      foreach($bitfields as $feature)
	      {
		  echo $feature . ($version['features'] & constant($feature) ? ' matches' : ' does not match');
		  echo PHP_EOL;
	      }
	      ?>
