我也不知道我问题标题的描述是否正确。
我正在做一个项目,里面用到了一些php + html格式的代码,然后我需要把上面的所有的输出的html结果保存到一个缓存中。
我现在唯一的办法就是把要保存的php+html格式代码写成类似
$cache = "html".php."html";
然后才能缓存这个$cache变量。
有没有办法让我把这些php + html代码放到一个文件中,然后读取他们输出的效果到一个变量里面?
例如我有这么一些代码
<code><div class="article row_3" onmouseover="this.style.cssText='background-color:<?php echo $hue[$i-1]; ?>'" onmouseout="this.style.cssText='background: #333;'"> <p><?php $post_describe = get_post_meta($post->ID,'post_describe',true);if(!$post_describe){echo strimwidth(strip_tags(apply_filters('the_content', $post->post_content)), 0, 142, '');}else{echo $post_describe;}?></p> </div></code>
代码中有一些if判断之类的语句,我不方便吧他们全部写在一行,然后丢一个变量里面。这样很不利于后期修改。
所以我寻求其他更好的办法。
我发现使用include 会直接输出文件中的内容,而不会返回内容给一个变量。

这是个好问题。实际上这就是在直接把php当模板语言来用。

看这里的 Example #6 Using output buffering to include a PHP file into a string
不被php代码约束的内容输出到响应,你是阻拦不了的,只能这样用重定向的方法来捕获之。
解决了,在include中间加入
<code>ob_start(); 你的代码 $html = ob_get_contents(); ob_end_clean();</code>
ob_start之后可以把输出的内容放到缓冲区内,而不是直接返回给用户,然后通过ob_get_contents获取到

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.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.
