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。
回复讨论(解决方案)
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。

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。。。。。。

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
