Q: For what reasons is PHP better than other CGIs? Is there any more specific data that can prove the efficiency of PHP execution compared with other CGI executions? Now my company uses C to write CGI. If I switch to PHP, what will happen? Isn't it better? Without a strong basis, I won't be able to convince the people above to let me switch to PHP... A: I think "good" must have three points. First: the execution of the written program. Fast. Second: The execution performance is strong when there is a large amount of access. Third: The program development time is fast and easy to maintain. Among these three points, PHP is not necessarily the best, but it is still at the top. The following is the comparison of C, PHP and Perl in terms of speed. I used the following calculation to test $s=1.0; for ($i= 1;$i Then use ab -n 10000 -c 20 http://mycgi to test. The result is that C language took 37.511 seconds, PHP3 took 45.393 seconds, and PERL took 68.418 seconds. It seems that C is the fastest, but , there is not much difference between the results of PHP3. Perl is the slowest.
