如何用php检测iOS版本？

Question

How to detect iOS version with php. I am trying to work with the solution $_SERVER['HTTP_USER_AGENT'] but it display:

Mozilla/5.0 (iPhone; U; CPU iPhone OS 8_0 like Mac OS X; en-us) AppleWebKit/532.9 (KHTML, like Gecko) Version/4.0.5 Mobile/8A293 Safari/6531.22.7

I want to display OS 8_0 only.

Any help would be appreciated.

Answer 1

As you mention you have use $_SERVER['HTTP_USER_AGENT']

So output is

Mozilla/5.0 (iPhone; U; CPU iPhone OS 8_0 like Mac OS X; en-us) AppleWebKit/532.9 (KHTML, like Gecko) Version/4.0.5 Mobile/8A293 Safari/6531.22.7

In above output is contains the version of that(see bold text on above)

if (strpos($_SERVER['HTTP_USER_AGENT'], 'OS 8_0') !== false) 
{
    echo "This is iOS 8";
}
else{
    echo "This is not iOS 8";}
}
