本文实例分析了php提交post数组参数的用法。分享给大家供大家参考,具体如下:
首先php中要想从页面传送数组到服务端a,要在页面上多个空间同名,而且对于名称有要求,那就是 name="aa[ ]",注意这里要多加一个数组的符号,这样才能在服务端a取到
得到的为数组。
更深一层的问题是,假设我现在需要对post中的参数进行处理后,再传送给另外一个服务端,对于参数aa,应该怎么传递呢?
如果不做什么处理,拼装完post请求后,服务端b获取到的永远只是Array,无法取到实际值。
现在的解决方案是:现在服务端a进行序列化,然后在服务端b接收后进行反序列化。这样反序列化后的值就是一个数组了,和a段获取到的一样。
序列化
反序列化
$a = "a:2:{i:0;s:1:\"1\";i:1;s:1:\"2\";}"; var_dump(unserialize($a));
结果是什么呢:
array(2) { [0]=> string(1) "1" [1]=> string(1) "2" }
而在post中获取到的序列化后的参数是有进行添加过转义符的,获取后需要去掉,然后才能反序列化成功
$bb = $_POST["aa"]; $bb = str_replace("\\", '', $bb); var_dump(unserialize($a));
好了,这样才是你要的结果。
当然,还有一种问题是,你可以直接把数组值传递给页面的某一空间,提交给服务端。这种情况同样需要序列化和反序列化。
页面
<input type="hidden" name="aa" value="<?php echo base64_encode(serialize($array));?>" /> var_dump(base64_decode(unserialize(<pre class="html" name="code">{1}
POST['post_data'])));
不知道加了这个base64_encode有什么作用,貌似是给中文编码的吧?
希望本文所述对大家php程序设计有所帮助。

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
