Question

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.

是否有一个简单的算法将24个轨道版本改为插图?

Answer 1

您指的是这一版本。

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

轻视:

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

该版本的编号为 he,3个数值,各取一,改为ci:

   07: 7
   0f: 15
   05: 5

Answer 2

It could be something in this spirit:

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