php接收POST数据的三种方式
1、$_POST 方式接受数据
$_POST 方式是由通过HTTP的POST方法传递过来的数据组成的数组,是一个自动全局变量。
注：只能接收Content-Type:application/x-www-form-urlencode提交的数据。也就是只能接收表单过来的数据。
2、GLOBLES[‘HTTP_RAW_POST_DATA’]
如果访问原始POST数据不是php能够识别的文档类型，比如:text/xml 或者soap等等，可以用$GLOBLES[‘HTTP_RAW_POST_DATA’]来接收，$HTTP_RAW_POST_DATA变量包含有原始POST数据。此变量仅在碰到未识别的MIME数据时产生。
注：$HTTP_RAW_POST_DATA对于enctype=”multipart/form-data”表单数据不可用，也就是说使用$HTTP_RAW_POST_DATA无法接受网页表单post过来的数据。
3、file_get_contents(“php://input”);
如果访问原始POST数据，更好的方法是使用file_get_content(“php://input”)；对于未指定Content-Type的POST数据，可以使用该方法读取POST原始数据，包括二进制流也可以和$HTTP_RAW_POST_DATA比起来。它带来的生存眼里更小，并且不需要任何特殊的php.ini设置。
注：php://input不能用于 enctype=”multipart/form-data”
例如：$postStr = file_get_contents("php://input"); //获取POST数据
乱码主要以下几个原因：
1。数据表中，表本身的编码 和 字段编码，均为UTF8。
2。在写入数据等数据库操作前，发送语句 'set names utf8'
3。PHP文件都是UTF8编码，无签名（无BOM）
4。页面上使用header或meta保证输出的页面是UTF8编码。meta http-equiv="Content-Type" content="text/html; charset=utf-8" /
