translating curl_version() 24-bit version number to version string

curl_version() returns (among other things) a 24-bit version number as well as the version string. 24-bit version number 463623 corresponds to string version 7.19.7.

Is there a simple algorithm for converting the 24-bit version to the string?

You mean this version number?

$v = curl_version();
echo $v['version']; # e.g. 7.15.5

It's easy to decipher:

$v = curl_version();
$n = $v['version_number'];
printf("%06x", $n); # e.g. 070f05

The version number is hex-decimal, 3 values, pick each one, convert to decimal:

   07: 7
   0f: 15
   05: 5

See: http://curl.haxx.se/docs/versions.html

It could be something in this spirit:

printf("%d.%d.%d", $version >> 16, ($version >>8)&0xff, $version & 0xff);
