PHP comments will not affect efficiency performance

Comments are affected because the comments make the file a little larger, and it takes a bit of IO to load the file, that's all. The compiler ignores comments. But now the hard drive interface rate can reach 6G, the memory frequency can reach 2400MHZ, this can be completely ignored.

The PHP engine does not parse empty lines and annotations directly, ignoring them. They do not participate in the calculation of the number of lines of code nor participate in the execution of the program, the efficiency of program execution has no effect
