As mentioned above, many times we need to know the user’s browser type
- /**
- */
- function get_user_browser()
- {
- if (empty($_SERVER['HTTP_USER_AGENT']))
- {
- return '';
- }
-
- $agent = $_SERVER['HTTP_USER_AGENT'];
- $browser = '';
- $browser_ver = '';
-
- if (preg_match('/MSIEs([^s|;]+)/i', $agent, $regs))
- {
- $browser = 'Internet Explorer';
- $browser_ver = $regs[1];
- }
- elseif (preg_match('/FireFox/([^s]+)/i', $agent, $regs))
- {
- $browser = 'FireFox';
- $browser_ver = $regs[1];
- }
- elseif (preg_match('/Maxthon/i', $agent, $regs))
- {
- $browser = '(Internet Explorer ' .$browser_ver. ') Maxthon';
- $browser_ver = '';
- }
- elseif (preg_match('/Opera[s|/]([^s]+)/i', $agent, $regs))
- {
- $browser = 'Opera';
- $browser_ver = $regs[1];
- }
- elseif (preg_match('/OmniWeb/(v*)([^s|;]+)/i', $agent, $regs))
- {
- $browser = 'OmniWeb';
- $browser_ver = $regs[2];
- }
- elseif (preg_match('/Netscape([d]*)/([^s]+)/i', $agent, $regs))
- {
- $browser = 'Netscape';
- $browser_ver = $regs[2];
- }
- elseif (preg_match('/safari/([^s]+)/i', $agent, $regs))
- {
- $browser = 'Safari';
- $browser_ver = $regs[1];
- }
- elseif (preg_match('/NetCaptors([^s|;]+)/i', $agent, $regs))
- {
- $browser = '(Internet Explorer ' .$browser_ver. ') NetCaptor';
- $browser_ver = $regs[1];
- }
- elseif (preg_match('/Lynx/([^s]+)/i', $agent, $regs))
- {
- $browser = 'Lynx';
- $browser_ver = $regs[1];
- }
-
- if (!empty($browser))
- {
- return addslashes($browser . ' ' . $browser_ver);
- }
- else
- {
- return 'Unknow browser';
- }
- }
