基于什么样的理由PHP比其它CGI好呢?_PHP

A:
我认为"好" 要有三点
第一: 写出来的程式的执行速度快.
第二: 遇到有大量存取时的执行效能强.
第三: 程式开发的时间快，易维护。
php在这三点中，虽都不一定是最好的，但也都在前茅

以下是C,PHP和Perl在速度方面的比较
我用下面的算式测试
$s=1.0;
for ($i=1;$i<=10;$i++) {
for ($j=1;$j<=10;$j++) {
$s=$s*1.0005;
$s=$s/1.0004;
};
};
print $s;
?>
然后用ab -n 10000 -c 20 http://mycgi
测试，结果
C语言用了 37.511 秒
PHP3用了 45.393 秒
PERL用了 68.418 秒

看起是C 最快没错，不过，和PHP3的结果没有太大
的差距。
Perl最慢
