php get和post的区分
1.get在浏览器回退是无害,而post会再次要求;
2.get发生的url地点能够被珍藏,而post不会;(推荐学习:PHP编程从入门到精通)
3.get要求参数会被完全保存在浏览器历史记录立,而post参数不会保存;
4.get参数经由过程url通报,post放在request boby中;
5.get要求在url中通报的参数有长度限定,而post没有;
6.地址栏里GET有参数,post无参数。
是否是GET提交
function isGet(){ return $_SERVER['REQUEST_METHOD'] == 'GET' ? true : false; }
是否是POST提交
function isPost(){ return ($_SERVER['REQUEST_METHOD'] == 'POST' && checkurlHash($GLOBALS['verify']) &&(empty($_SERVER['HTTP_REFERER']) || preg_replace("~https?:\/\/([^\:\/]+).*~i", "\\1", $_SERVER['HTTP_REFERER']) == preg_replace("~([^\:]+).*~", "\\1", $_SERVER['HTTP_HOST']))) ? 1 : 0; }
