PHP 日历中有错误

Question

我有一个非常简单的 PHP 日历脚本，但是当我尝试它时，有一个字符串我没有写。然后出现 "nnnnnnnnnnnnnnnnnn" 但是没有像 echo "nnnnnnnnnnnnnn" 这样的东西所以我不知道是什么错误。请帮助我。

代码：

<?php

$monthNames = Array("Gennaio", "Febbraio", "Marzo", "Aprile", "Maggio", "Giugno", "Lulglio", 
"Agosto", "Settembre", "Ottobre", "Novembre", "Dicembre");

if (!isset($_REQUEST["month"])) $_REQUEST["month"] = date("n");
if (!isset($_REQUEST["year"])) $_REQUEST["year"] = date("Y");

$cMonth = $_REQUEST["month"];
$cYear = $_REQUEST["year"];

$prev_year = $cYear;
$next_year = $cYear;
$prev_month = $cMonth-1;
$next_month = $cMonth+1;

if ($prev_month == 0 ) {
     $prev_month = 12;
     $prev_year = $cYear - 1;
}
if ($next_month == 13 ) {
    $next_month = 1;
    $next_year = $cYear + 1;
}

?>
<html>

<?php 
$timestamp = mktime(0,0,0,$cMonth,1,$cYear);
$maxday = date("t",$timestamp);
$thismonth = getdate ($timestamp);
$startday = $thismonth['wday'];
for ($i=0; $i<($maxday+$startday); $i++) {
    if(($i % 7) == 0 ) echo "<tr>n";
    if($i < $startday) echo "<td></td>n";
    else echo "<td align='center' valign='middle' height='20px'>". ($i -         $startday + 1) . "</td>n";
    if(($i % 7) == 6 ) echo "</tr>n";
}
?>

</td>

Answer 1

您看到 n 位于：

for ($i=0; $i<($maxday+$startday); $i++) {
    if(($i % 7) == 0 ) echo "<tr>n";
    if($i < $startday) echo "<td></td>n";
    else echo "<td align='center' valign='middle' height='20px'>". ($i - $startday + 1) . "</td>n";
    if(($i % 7) == 6 ) echo "</tr>n";
}

要么删除它们，要么您可能打算使用 \n

将其写出 HTML

if(($i % 7) == 0 ) echo "<tr>" . "\n";

或

if(($i % 7) == 0 ) echo "<tr>\n";

其他人也一样，用同样的方法。

将它们连接起来。
