How to Preserve HTML Content in PHP: A Step-by-Step Guide

Preserving HTML content can sometimes be a tricky task, especially when dealing with unwanted characters and formatting issues. If you've encountered issues with HTML content generated by PowerMTA, you might have noticed that your original content ends up with messy extra characters like =0A for line breaks and =3D for equals signs. In this post, we will explore how to clean and preserve your HTML content correctly using PHP.

The Problem

The HTML snippet you're working with, which can be thought of as Content-1, may look something like this:

As you can see, the HTML content has become cluttered with unwanted characters. Your goal is to transform this messy content back into a clean and properly formatted HTML snippet, which we'll refer to as Content-2.

The Solution

To achieve this, we can write a PHP script that will perform the necessary parsing and cleaning of Content-1. Below are the steps we'll follow in our PHP script:

Steps to Preserve HTML Content

Load the Content: Use file_get_contents() to read the content from a source file.

Replace Unwanted Characters: Utilize str_replace() to remove unwanted sequences and keep the necessary characters.

Create Clean Lines: Loop through each line of your content to ensure that it is cleaned correctly, especially the last character.

Save Clean Content: Write the cleaned content back into a new file.

Sample PHP Code

Here's a simplified version of the PHP script you'll need to preserve your HTML content:

How Does This Work?

Loading Content: The script starts by loading the messy content from a specified text file.

Cleaning Up the Content: It identifies and removes unwanted characters (=3D for equal signs and =0A for new lines).

Stripping Extra Characters: By using substr(), the script effectively removes any trailing unwanted characters.

Outputting Clean HTML: Finally, the cleaned content is saved into a new file for further use.

Conclusion

By following the steps outlined above, you can easily preserve your HTML content, removing any undesired artifacts while ensuring that your HTML retains its intended formatting. This approach can prove invaluable when working with generated content from systems like PowerMTA. Don't let messy HTML slow down your projects; implement the provided PHP script to clean it up!
