PHP's approach to judging iphone, IPad, Android, and PC devices

Because the job needs us to know what it is. The user visited my website, now there are many kinds of mobile devices, let's look at the small compilation of a section of PHP to determine the iphone, IPad, Android, PC device examples.

Note: This code of the PC system for Windows

The principle is to determine the user AGENT submitted by the browser

<?php

Get the user AGENT

$agent = Strtolower ($_server[' http_user_agent ');

Make judgments

$is _pc = (Strpos ($agent, ' Windows NT '))? True:false;

$is _iphone = (Strpos ($agent, ' iphone ')? True:false;

$is _ipad = (Strpos ($agent, ' ipad ')? True:false;

$is _android = (Strpos ($agent, ' Android ')? True:false;

if ($is _pc)

{

echo "This is PC";

}

if ($is _iphone)

{

echo "This is the iphone";

}

if ($is _ipad)

{

echo "This is the ipad";

}

if ($is _android)

{

echo "This is Android";

}

If you only determine whether the iphone device can be operated as follows, the code is as follows:

<?php

function Get_device_type () {

$agent = Strtolower ($_server[' http_user_agent ');

$type = ' other ';

if (Strpos ($agent, ' iphone ') | | strpos ($agent, ' ipad '))

{

$type = ' iOS ';

}

if (Strpos ($agent, ' Android '))

{

$type = ' Android ';

}

return $type;

}

?>
