PHP function checks whether the browser on the computer accesses the website or the browser on the mobile phone.

The PHP function determines whether the browser on the computer accesses the function or where the browser access on the mobile phone forgets to obtain the function. I just cannot find it in a package and save it temporarily.

/*** Whether to access the mobile terminal ** @ return bool */function isMobile () {// if there is HTTP_X_WAP_PROFILE, it must be a mobile device if (isset ($ _ SERVER ['http _ X_WAP_PROFILE ']) {return true ;} // if the via information contains wap, it must be a mobile device. some service providers will block this information if (isset ($ _ SERVER ['http _ VE']) {// cannot be found as flase; otherwise, it is true return stristr ($ _ SERVER ['http _ vean'], "wap ")? True: false;} // identify the client flag sent by the mobile phone. the compatibility needs to be improved if (isset ($ _ SERVER ['http _ USER_AGENT ']) {$ clientkeywords = array ('Nokia ', 'Sony', 'ericsson ', 'MOT', 'Samsung', 'HTC ', 'sgh', 'LG ', 'Sharp ', 'sie-', 'Philips ', 'panasonic', 'alcatel', 'Lenovo ', 'iPhone', 'iPod ', 'BlackBerry ', 'meizu', 'Android', 'netfront', 'symbian ', 'ucweb', 'windowsce', 'Palm ', 'operamini', 'operamobi', 'openwave ', 'nexusone', 'cld C ', 'midp', 'wap ', 'mobile'); // search for the keyword if (preg_match ("/(". implode ('|', $ clientkeywords ).
