php动态添加url查询参数的方法，php动态url参数

本文实例讲述了php动态添加url查询参数的方法。分享给大家供大家参考。具体分析如下：

这段代码可以动态为url添加key-value查询参数，如果参数已经存在则会用新的进行覆盖

function add_querystring_var($url, $key, $value) {
 $url=preg_replace('/(.*)(&#63;|&)'.$key.'=[^&]+&#63;(&)(.*)/i','$1$2$4',$url.'&');
 $url=substr($url,0,-1);
 if(strpos($url,'&#63;') === false){
  return ($url.'&#63;'.$key.'='.$value);
 } else {
  return ($url.'&'.$key.'='.$value);
 }
}

希望本文所述对大家的php程序设计有所帮助。
