php addtype: "While some users prefer to use PHP in conjunction with the .html extension, keep in mind that doing so will ultimately cause the file to be passed to PHP for parsing every single time an HTML file is requested.Some people may consider this convenient, but it will come at the cost of performance." can't catch up with this paragraph. supposeed a file's suffix is .html,there is no php in it. does it to be passed to PHP for parsing ? if no, why the above says "keep in mind that doing so will ultimately cause the file to be passed to PHP for parsing every single time an HTML file is requested"

many thanks,got it, now,$days[] is an arry,which value is sat,aun,mon..the rest i also don't catch up with it. i don't find the place that declare this $starting_day variable. for ($i=0; $i<$starting_day; $i++) $days[] = " "; for ($i=1; $i< ($total_day_of_month+1); $i++) $days[] = $i;
-
in this line , foreach (array_keys($week_days) as $day),why this array_keys($week_days) is not $week_days.why it use array_keys($week_days).
-
$date = "10/01/2005"; $week_days = array("Sat"=>1, "Sun"=>2, "Mon"=>3,"Tue"=>4,"Wed"=>5, "Thu"=>6,"Fri"=>7); $total_day_of_month = get_total_day($date); $starting_day = $week_days[Date("D",strtotime($date))] - 1; foreach (array_keys($week_days) as $day) $days[] = $day; for ($i=0; $i<$starting_day; $i++) $days[] = " "; for ($i=1; $i< ($total_day_of_month+1); $i++) $days[] = $i; $smarty->assign("title","October 2005"); $smarty->assign("special_days", $days); $smarty->display("calendar.tpl"); function get_total_day($date) { $time_stamp = strtotime($date); $month_ar = split("/", $date); $month = $month_ar[0]; $year = Date("Y",$time_stamp); for ($i=28; $i<33; $i++) { if (!checkdate($month, $i, $year)){ return ($i - 1); } } } this code is from a php file,which use the smarty template.can't understand the get_total_day($date) function,why the $i value starts from 28,and ends on 32.any tips would be appreciated.
