Comment (by chriscct7):

 Yes but it does that while producing the opcodes, not when it runs those
 opcodes for execution. Most servers use an opcache layer, so you're not
 compiling the opcodes for each runtime, and therefore there's no
 difference. Even where ones where there's no opcaching enabled, in modern
 day (PHP 5.2+, particularly in PHP 7.x branches which WP is moving toward
 making it's minimum supported PHP version by EOL) PHP the speed of lexing
 for a variable is so fast that there is no measurable difference even if
 you run the test runs millions of times.

 It's like removing a fly from an aircraft carrier to save weight & fuel
 consumption. In theory can it make a difference, yes. In any production
 environment will it ever make a difference, no.

 A good resource that explains a lot of this can be found at
