note 123473 added to function.get-browser

Follow up to Francesco R's post from 2016. His function works for most human traffic; added a few lines to cover the most common bot traffic. Also fixed issue with function failing to detect strings at position 0 due to strpos behavior. <?php // Function written and tested December, 2018 function get_browser_name($user_agent) { // Make case insensitive. $t = strtolower($user_agent); // If the string *starts* with the string, strpos returns 0 (i.e., FALSE). Do a ghetto hack and start with a space. // "[strpos()] may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE." // http://php.net/manual/en/function.strpos.php $t = " " . $t; // Humans / Regular Users if (strpos($t, 'opera' ) || strpos($t, 'opr/') ) return 'Opera' ; elseif (strpos($t, 'edge' ) ) return 'Edge' ; elseif (strpos($t, 'chrome' ) ) return 'Chrome' ; elseif (strpos($t, 'safari' ) ) return 'Safari' ; elseif (strpos($t, 'firefox' ) ) return 'Firefox' ; elseif (strpos($t, 'msie' ) || strpos($t, 'trident/7')) return 'Internet Explorer'; // Search Engines elseif (strpos($t, 'google' ) ) return '[Bot] Googlebot' ; elseif (strpos($t, 'bing' ) ) return '[Bot] Bingbot' ; elseif (strpos($t, 'slurp' ) ) return '[Bot] Yahoo!
