本文实例讲述了php自定义urlencode,urldecode函数。分享给大家供大家参考。具体如下:

//配合JavaScript的ajaxObject函数, 对字串进行转码.
function ajax_encode($str){
  $patern = array("/%/","/=/","/&/");
  // % 必须是第一个项, 替换是按项的顺序进行的.
  $rp = array("%25","%26","%3D");
  return preg_replace($patern,$rp,$str);
}
//逆函数
function ajax_decode($str){
  $patern = array("/%25/","/%26/","/%3D/");
  $rp = array("%","=","&");
  return preg_replace($patern,$rp,$str);
}
Copy after login

希望本文所述对大家的php程序设计有所帮助。
