我的 smart404.php 代码中有一个全局变量 debug_smart404：

$debug_smart404 = intval(get_option('debug_smart404' ));
    error_log("smart404_redirect: debug_smart404 =" . ( $debug_smart404 ) );

我使用了很多地方：

if ( $debug_smart404 > 4 ) # lotsa debug!
{
    error_log("smart404_redirect: take_1st_match=" . ( $take_1st_match  ? "yes" : "no" ) );
    error_log("smart404_redirect: take_exact_match=" . ( $take_exact_match ? "yes" : "no" ) );
    error_log("smart404_redirect: search_whole_uri=" . ( $search_whole_uri ? "yes" : "no" ) );
    error_log("smart404_redirect: walk_uri=" . ( $walk_uri ? "yes" : "no" ) );
    error_log("smart404_redirect: ignored_patterns_input=" . $patterns );
    error_log("smart404_redirect: ignored_patterns_array=" . join($patterns_array,",") );
            error_log("smart404_redirect: search_groups=" . join($search_groups,","));
}
while ( TRUE )
{
    error_log("smart404_redirect:inside while: debug_smart404 =" . ( $debug_smart404 ) );
...
    if ( $debug_smart404 > 3 ) # less debug
    {
        error_log("smart404_redirect: search_words=" . $search_words);
        }
...
        if ( $debug_smart404 > 0 ) {
            error_log("smart404_redirect: uri=" . $uri . "= #matches=" . $mct);
        } 
...
} #end while...

所以当我设置 debug_smart404 == 5 时，我得到了 while 之外实例的预期输出：

[Thu Mar 14 08:32:42 2013] [error] [client xx.xx.xx.xx] smart404_redirect: debug_smart404 =5

但请注意，while 循环的 if 语句中的 error_log 输出丢失了……但仅在我的生产服务器（netsol vps）上

它在我的测试服务器（lighttpd）上运行良好：

2013-03-14 08:26:40: (mod_fastcgi.c.2711) FastCGI-stderr: smart404_redirect: debug_smart404 =5

smart404_redirect: take_exact_match=no
smart404_redirect: search_whole_uri=yes
smart404_redirect: walk_uri=yes
smart404_redirect: ignored_patterns_input=wp-.*

smart404_redirect: search_groups=pages,posts,categories
smart404_redirect:inside while: debug_smart404 =5
smart404_redirect: search_words=cavitronix.com  xxx zzzxxxx
smart404_redirect: uri=/cavitronix.com//xxx/zzzxxxx= #matches=0

呜呜呜？？？在两者上运行 php5，并且它曾经在 vps 上工作（此处调试 = 1 输出）-：

[Thu Mar 14 06:32:55 2013] [error] [client xx.xx.xx.xx] smart404_redirect: uri=/how-it-works= #matches=1
[Thu Mar 14 06:41:32 2013] [error] [client xx.xx.xx.xx] smart404_redirect: uri=/videos/e2c-overview/private/awstats/current/new.html= #matches=10
[Thu Mar 14 06:53:38 2013] [error] [client xx.xx.xx.xx] smart404_redirect: uri=/current/previous.html= #matches=3
[Thu Mar 14 06:54:47 2013] [error] [client xx.xx.xx.xx] smart404_redirect: uri=/press-releases= #matches=3

或者这是netsol的vpshackery的一些功能？

打印while里面的错误日志；您自己从生产服务器粘贴的错误日志显示它“在内部同时：debug_smart404 = 5”

您错过了“...”背后的很多代码。您的代码是否有可能进入 while 循环，但随后（在生产中）在到达其他错误日志语句之前快速中断/或继续。你能积极排除吗？
