With the popularization of mobile devices, more and more mobile devices will access websites. Pages adapted to PCs are often unfriendly to mobile phone users. In some cases, we need to determine whether or not users access the pages through mobile phones, to go to the specified mobile friendly page. Here we will introduce how to determine whether a user can access the website through a mobile phone.

The custom functions are as follows:

The Code is as follows:

$ Agent = check_wap ();
If ($ agent)
{
Header ('location :');
Exit;
}
// Check if wap
Function check_wap (){
// Check whether it is a wap proxy with High Accuracy
If (stristr ($ _ SERVER ['HTTP _ pass'], "wap ")){
Return true;
}
// Check whether the browser accepts WML.
Elseif (strpos (strtoupper ($ _ SERVER ['HTTP _ ACCEPT ']), "VND. WAP. WML")> 0 ){
Return true;
}
// Check USER_AGENT
Elseif (preg_match ('/(blackberry | configuration \/cldc | hp-| htc _ | htc-| iemobile | kindle | midp | mmp | motorola | mobile | nokia | opera mini | opera | Googlebot-Mobile | YahooSeeker \/M1A1-R2D2 | android | iphone | ipod | mobi | palm | palmos | pocket | portalmmm | ppc; | smartphone | sonyericsson | sqh | spv | symbian | treo | up. browser | up. link | vodafone | windows ce | xda _)/I ', $ _ SERVER ['HTTP _ USER_AGENT']) {
Return true;
}
Else {
Return false;
}
}

Another function is used to determine whether a mobile terminal is a mobile phone from the PHP framework:

The Code is as follows:

Function is_mobile_request ()
{
$ _ SERVER ['all _ http'] = isset ($ _ SERVER ['all _ http'])? $ _ SERVER ['all _ http']: '';
$ Mobile_browser = '0 ';
If (preg_match ('/(up. browser | up. link | mmp | symbian | smartphone | midp | wap | phone | iphone | ipad | ipod | android | xoom)/I ', strtolower ($ _ SERVER ['HTTP _ USER_AGENT '])
$ Mobile_browser ++;
If (isset ($ _ SERVER ['HTTP _ ACCEPT ']) and (strpos (strtolower ($ _ SERVER ['HTTP _ ACCEPT']), 'application/vnd.wap.xhtml + xml ')! = False ))
$ Mobile_browser ++;
If (isset ($ _ SERVER ['HTTP _ X_WAP_PROFILE '])
$ Mobile_browser ++;
If (isset ($ _ SERVER ['HTTP _ PROFILE '])
$ Mobile_browser ++;
$ Mobile_ua = strtolower (substr ($ _ SERVER ['HTTP _ USER_AGENT '], 0, 4 ));
$ Mobile_agents = array (
'W3c ', 'acs-', 'alav', 'alca', 'amodi', 'audi', 'avany', 'benq', 'bird ', 'blac ',
'Blaz', 'brew', 'cell ', 'cldc', 'cmd-', 'dang', 'Doc', 'Eric ', 'hipt ', 'inno ',
'Ipaq ', 'java', 'glasis', 'dkdi', 'keji', 'leno', 'lg-C', 'lg-d ', 'lg-G', 'lge -',
'Maui', 'maxo', 'midp ', 'mits', 'mmef', 'mobi', 'mot-', 'moto', 'mwbp ', 'nec -',
'Newt ', 'noki', 'login', 'palm', 'pana ', 'pant', 'Phil', 'play', 'Port', 'prox ',
'Qwap ', 'sage', 'samples', 'sany', 'sch-', 'sec-', 'send', 'seri', 'sgh -', 'shar ',
'Sie-', 'siem', 'smal', 'smar ', 'sony', '7d-', 'symb','t-m', 'teli ', 'Tim -',
'Tosh', 'tsm-', 'upg1', 'upsi', 'vk-V', 'voda', 'wap-', 'wapa', 'wapi ', 'wapp ',
'Wapr', 'webc', 'winw', 'winw', 'xda', 'xda -'
);
If (in_array ($ mobile_ua, $ mobile_agents ))
$ Mobile_browser ++;
If (strpos (strtolower ($ _ SERVER ['all _ http']), 'operamini ')! = False)
$ Mobile_browser ++;
// Pre-final check to reset everything if the user is on Windows
If (strpos (strtolower ($ _ SERVER ['HTTP _ USER_AGENT ']), 'windows ')! = False)
$ Mobile_browser = 0;
// But WP7 is also Windows, with a slightly different characteristic
If (strpos (strtolower ($ _ SERVER ['HTTP _ USER_AGENT ']), 'windows phone ')! = False)
$ Mobile_browser ++;
If ($ mobile_browser> 0)
Return true;
Else
Return false;
}

The code is very simple, the function is very practical, it is very suitable for putting it into the project, hope that friends can like it.
