Is PHP minification helpful?

Question

I can understand that by minifing js code will reduce its size and will be helpful for sending over the network but will it be useful to minify php?

also how obfuscation will be helpful in execution in php?

Answer 1

Minifying php is pointless from a network bandwidth perspective, minifying the output of the php might be beneficial however as the html that is output is transmitted. The original php will be hard to maintain if it's minified. Which is also the point of obsfucation. If someone gets hold of your php, then it will prevent them knowing what it does without more effort...

Answer 2

PHP code is (generally) not transmitted over HTTP (unlike CSS, JavaScript & HTML) so minifying it would be pointless, not to mention making your code unnecessarily unreadable.
