前面已经分享了PHP常用功能代码片段(1~5)和PHP常用功能代码片段(6~10)，今天是第三篇，也就是第11到15这5个实现代码片段，希望可以帮到jquery学堂群里面的成员和广大对PHP开发的网友们提高开发效率，以下是第三篇文章。
11、PHP实现如何获取网址的PR值
/**功能:对URL进行编码*参数说明:$web_url 网站URL，不包含"http://"*/function HashURL($url){ $SEED = "Mining PageRank is AGAINST GOOGLE’S TERMS OF SERVICE. Yes, I’m talking to you, scammer."; $Result = 0x01020345; for ($i=0; $i<strlen($url); $i++) { $Result ^= ord($SEED{$i%87}) ^ ord($url{$i}); $Result = (($Result >> 23) & 0x1FF) | $Result << 9; } return sprintf("8%x", $Result);}/**功能:根据google提供的pr查询接口获取pagerank*参数说明:$domain 网站域名，不包含"http://"*/function pagerank($domain){ $StartURL = "http://toolbarqueries.google.com/tbr?client=navclient-auto&features=Rank:&q=info:"; $GoogleURL = $StartURL.$domain. '&ch='.HashURL($domain); echo $GoogleURL.'<br>'; $fcontents = file_get_contents("$GoogleURL"); $pagerank = substr($fcontents,9); if (!$pagerank) return "0";else return $pagerank;}//调用方法echo pagerank("www.jq-school.com");
12、PHP实现为post过来的数据转换编码

Avactis是一个强大的PHP在线购物系统拥有多个版本包括开源版本。它具备一个在线购物系统所需要的所有功能从产品到会员管理，订单和营销。可以无限分类和为产品指定任务数量的图片（支持自动生成缩略图）。使用自定义字段功能，让你可以更好地定义一个产品。该系统提供以非常灵活的方式来创建任意类型的促销活动如设置折扣代码，基于价格的折扣或基于数量的折扣等。
$info = array();foreach($_POST as $key => $value){ $info[$key] = iconv("utf-8","gb2312",$value);}
13、PHP实现获取客户端IP地址及所在地区
function address($ip) { $info = json_decode(file_get_contents('http://int.dpool.sina.com.cn/iplookup/iplookup.php?ip='.$ip.'&format=json'), false); if ($info ->ret == 1) { if ($info ->province != $info ->city) { return $info ->country.",".$info ->province."(".$info ->city.") ".$info ->district." ".$info ->desc; } else { return $info ->country.",".$info ->province." ".$info ->district." ".$info ->desc; } } else { return '地球'; }}
14、PHP实现取得客户端浏览器版本
function browser($ua) { if (stripos($ua, "Googlebot")) { $browser = "谷歌蜘蛛"; } elseif(stripos($ua, "Baiduspider") !== false) { $browser = "百度蜘蛛"; } elseif(stripos($ua, "Yahoo!") !== false) { $browser = "雅虎蜘蛛"; } elseif(stripos($ua, "bingbot")) { $browser = "必应蜘蛛"; } elseif(stripos($ua, "YRSpider")) { $browser = "云壤蜘蛛"; } elseif(stripos($ua, "Yeti") !== false) { $browser = "Naver蜘蛛"; } elseif(stripos($ua, "Maxthon")) { if (stripos($ua, "AppleWebKit")) { $browser = "遨游浏览器(极速模式)"; } elseif(stripos($ua, "Trident")) { $browser = "遨游浏览器(兼容模式)"; } elseif(stripos($ua, "MAXTHON 2.0")) { $browser = "遨游浏览器2.0"; } } elseif(stripos($ua, "Firefox")) { $browser = "火狐浏览器"; } elseif(stripos($ua, "Opera") == 0 && stripos($ua, "Presto")) { $browser = "Opera"; } elseif(stripos($ua, "BIDUBrowser")) { if (stripos($ua, "Trident")) { $browser = "百度浏览器(兼容模式)"; } elseif(stripos($ua, "AppleWebKit")) { $browser = "百度浏览器(极速模式)"; } } elseif(stripos($ua, "Ruibin")) { $browser = "瑞影浏览器"; } elseif(stripos($ua, "qihu theworld")) { if (stripos($ua, "Trident")) { $browser = "世界之窗浏览器"; } elseif(stripos($ua, "AppleWebKit")) { $browser = "世界之窗浏览器(极速模式)"; } } elseif(stripos($ua, "MetaSr")) { if (stripos($ua, "Trident")) { $browser = "搜狗高速浏览器(兼容模式)"; } elseif(stripos($ua, "AppleWebKit")) { $browser = "搜狗高速浏览器(极速模式)"; } } elseif(stripos($ua, "LBBROWSER")) { if (stripos($ua, "Trident")) { $browser = "猎豹浏览器(兼容模式)"; } elseif(stripos($ua, "AppleWebKit")) { $browser = "猎豹浏览器(极速模式)"; } } elseif(stripos($ua, "YLMFBR")) { $browser = "115浏览器"; } elseif(stripos($ua, "QQBrowser")) { if (stripos($ua, "Trident")) { $browser = "QQ浏览器(兼容模式)"; } elseif(stripos($ua, "AppleWebKit")) { $browser = "QQ浏览器(极速模式)"; } } elseif(stripos($ua, "TencentTraveler")) { $browser = "腾讯TT浏览器"; } elseif(stripos($ua, "TaoBrowser")) { if (stripos($ua, "Trident")) { $browser = "淘宝浏览器(兼容模式)"; } elseif(stripos($ua, "AppleWebkit")) { $browser = "淘宝浏览器(极速模式)"; } } elseif(stripos($ua, "CoolNovo")) { $browser = "枫树浏览器"; } elseif(stripos($ua, "SaaYaa")) { $browser = "闪游浏览器"; } elseif(stripos($ua, "360SE")) { $browser = "360安全浏览器"; } elseif(stripos($ua, "360EE")) { if (stripos($ua, "Trident")) { $browser = "360极速浏览器(兼容模式)"; } elseif(stripos($ua, "AppleWebkit")) { $browser = "360极速浏览器(极速模式)"; } } elseif(stripos($ua, "Konqueror")) { $browser = "Konqueror"; } elseif(stripos($ua, "Chrome")) { $browser = "谷歌浏览器"; } elseif(stripos($ua, "Safari")) { $browser = "Safari"; } elseif(stripos($ua, "MSIE")) { $ver = explode(";", substr($ua, stripos($ua, "MSIE") + 5, 4)); $ver = $ver[0]; $browser = "IE ".$ver; } elseif(stripos($ua, "UCWEB")) { $browser = "UCWEB浏览器"; } elseif(stripos($ua, "WAP")) { $browser = "Mobile浏览器"; } else { $browser = $ua; } if ($browser == '') $browser = $ua; return $browser;}
15、PHP实现取得客户端操作系统版本
function os($ua) { $os = ""; if (stripos($ua, "Googlebot")) { $os = "谷歌蜘蛛"; } elseif(stripos($ua, "Baiduspider") !== false) { $os = "百度蜘蛛"; } elseif(stripos($ua, "Yahoo!") !== false) { $os = "雅虎蜘蛛"; } elseif(stripos($ua, "bingbot")) { $os = "必应蜘蛛"; } elseif(stripos($ua, "YRSpider")) { $os = "云壤蜘蛛"; } elseif(stripos($ua, "Yeti") !== false) { $os = "Naver蜘蛛"; } elseif(stripos($ua, "Windows NT")) { switch (substr($ua, stripos($ua, "Windows NT") + 11, 3)) { case 5.0: { $os = "Windows 2000"; break; } case 5.1: { $os = "Windows XP"; break; } case 5.2: { $os = "Windows 2003"; break; } case 6.0: { $os = "Windows Vista/2008"; break; } case 6.1: { $os = "Windows 7"; break; } case 6.2: { $os = "Windows 8"; break; } default: { $os = "Windows"; break; } } if (stripos($ua, "WOW64")) { $os.= "(X64)"; } else { $os.= "(X86)"; } } elseif(stripos($ua, "Android")) { $os = substr($ua, stripos($ua, "Android"), 11); } elseif(stripos($ua, "Linux")) { if (stripos($ua, "i686")) { $os = "Linux X86"; } else { $os = "Linux"; } if (stripos($ua, "X11")) { $os.= "(X Window)"; } } elseif(stripos($ua, "Macintosh")) { $os = "Mac"; } elseif(stripos($ua, "IOS")) { $os = "iOS"; } elseif(stripos($ua, "ZTE")) { $os = "ZTE"; } elseif(stripos($ua, "Windows 98")) { $os = "Windows 98"; } else { $os = "未知系统"; } return $os;}?
