How to remove unwanted “extra line breaks” that ap

Question

Consider the following:

• Zip up a folder, upload to server
• unzip on server using 'unzip archive.zip'
• Download any PHP file from that folder
• Extra line breaks appear where unwanted

Any ideas why this happens or how to "undo it"? I have tried to do a "find and replace" but that ends up basically minifying the entire file onto "1 line", which is not wanted either...

For the sake of posterity: I found that I was able to use this tactic: https://pixelflips.com/blog/removing-line-breaks-in-dreamweaver

• Open the Find/Replace box (CMD+F / CTRL+F)
• In the Find enter: [\r\n]{2,}
• In the Replace enter: \n
• Check the box "Use regular expression" and un-check any other boxes.
• The hit "Replace All"

By using Adobe Dreamweaver, which works...

However, I am not going to make my own answer correct as I still wonder why this happens and want to prevent it if possible.
