Now I got to know that single quotes are faster than double quotes!
Hey... more info should be shared about database speed too! Don't just stop there, please!

I'd rather use double quotes for long strings that need lots of variables because it makes the code more readable.

I guess these tips only apply if you're expecting a million hits per day or something. Otherwise, it's not worth the hassle.

@realluinnar Wrong. At that point, you're going into load-balancing, DB tuning and caching of all sorts; and if that fails, improve your algorithms. Do you think it makes a difference if a server is 99% or 98% loaded?

Dear Eric, don't put this video on your resume. It might make you look like an amateur, even though you have eight years of experience.

@benjarriola Actually, in PHP, a while loop will run faster. But the gain is not significant at all(something such as 0.001 seconds for iterations...), so it's not worth changing all your for loops for while in your scripts

This video its for someone as big as google!, this must be emailed to microsoft instead of make us watching it :D

It must be a joke.

Does Google actually use... PHP?

And the first example is priceless. "Imagine if a malicious user had inserted 512Kb worth of characters". Yeah, right, but the real issue is an obvious cross-scripting vulnerability. What a wonderful example.
And as pointed out by Noobenstein, PHP does COW for variables.
This is nothing but misinformation. It must be a joke, I can't believe this video has been made by Google.
Real PHP performance tip: use PHP-FPM.

These were the most insignificant performance tips ever to exist. Your benchmark towards the end was laughable. I'll bet you $100 you can't find a noticeable performance gain using these.

Proper performance tips include "caching database results", "using an op-code cache (APC)", "re-factoring loops", etc.

Actually, anything that what wasn't on the video would of been more useful.

print and echo are statements. Not functions.
" vs ' strings are identical in performance, after compiling.

And where is the genuinely important advice? Nothing about compile caches?
