PHP中类似Jsp的out.print的函数

Jun 23, 2016 pm 01:50 PM
jsp php function

本人菜鸟,没有用过jsp,自己百度了一下,感觉out.print 跟 echo 差不多,

但是用echo 服务器那边说没接到,提示返回:null

求各位大神指导。

out.print 是服务器端向客户浏览器输出的流
等价于 php 的
ob_start();
echo 

不知道你这是什么意思
是用echo 服务器那边说没接到,提示返回:null

就是他那个平台给我发个异步通知,需要我返回一个success或者error,他们是用jsp写的out.print(),我是php,异步通知一直没有成功,错误的原因提示返回:null

你是怎么传值过去,怎么接收值?

他相当于是直接访问我的网页(网页的地址是设定好的),我只需要 找到一个同out.print一样的函数,输出success或者error
就行。

?考下?? http://www.w3school.com.cn/php/func_string_printf.asp

你直接 echo 就是了
至于为什么会是 null 那要看你的程序了

返回null跟你使用了什么输出函数没关系!
echo print_r ....
可以向浏览器输出的都没问题!应该是你程序接收问题

最后竟然是对面防火墙的事,我表示。。。。。。
