Question

我写了一个php脚本，我希望该脚本能够执行，然后执行的结果将被保存到另一个文件，然后它将重定向到该保存文件。

现在我的问题是我执行的脚本有一些我需要保存的PHP代码，因为它在保存的文件中

<?php
function ago($time)
{
   $periods = array("second", "minute", "hour", "day", "week", "month", "year", "decade");
   $lengths = array("60","60","24","7","4.35","12","10");

   $now = time();

       $difference     = $now - $time;
       $tense         = "ago";

   for($j = 0; $difference >= $lengths[$j] && $j < count($lengths)-1; $j++) {
       $difference /= $lengths[$j];
   }

   $difference = round($difference);

   if($difference != 1) {
       $periods[$j].= "s";
   }

   return "$difference $periods[$j] 'ago' ";
}
?>

我试图从执行脚本中回显这些行，以便可以保存上面的行。我就是这样做的。

   <?php 
            function rowFromVar($last_modified) {
              $result  = " <?php   $$last_modified = filemtime(__FILE__);

                function ago($time)
                    {
                       $periods = array("second", "minute", "hour", "day", "week", "month", "year", "decade");
                       $lengths = array("60","60","24","7","4.35","12","10");

                       $now = time();

                           $difference     = $now - $time;
                           $tense         = "ago";

                       for($j = 0; $difference >= $lengths[$j] && $j < count($lengths)-1; $j++) {
                           $difference /= $lengths[$j];
                       }

                       $difference = round($difference);

                       if($difference != 1) {
                           $periods[$j].= "s";
                       }

                       return "$difference $periods[$j] 'ago' ";
                    }
                    $last=ago($last_modified);";

     return $result;

    }
    print rowFromVar("last_modified");

但我有一些错误，比如

    ( ! ) Parse error: syntax error, unexpected T_STRING in C:\wamp\www\SEO stat[Repica OF     server]\Tools\domain_lookup1.php on line 109

任何帮助将不胜感激。

<?php 
        function rowFromVar($last_modified) {
          $result  = <<<XXX_DELIMETER_XXX
<?php   \$last_modified = filemtime(__FILE__);

            function ago(\$time)
                {
                   \$periods = array("second", "minute", "hour", "day", "week", "month", "year", "decade");
                   \$lengths = array("60","60","24","7","4.35","12","10");

                   \$now = time();

                       \$difference     = \$now - \$time;
                       \$tense         = "ago";

                   for(\$j = 0; \$difference >= \$lengths[\$j] && \$j < count(\$lengths)-1; \$j++) {
                       \$difference /= \$lengths[\$j];
                   }

                   \$difference = round(\$difference);

                   if(\$difference != 1) {
                       \$periods[\$j].= "s";
                   }
XXX_DELIMETER_XXX;
                   return "$difference $periods[$j] 'ago' ";
                }
                $last=ago($last_modified);";

 return $result;

}
print rowFromVar("last_modified");

它应该有效，你正在使用未转义的双引号..
