使用表格时的 PHP 和 HTML 格式问题

Question

我一直在学习这个，因此我遇到了一个我似乎无法解决的恼人问题。

当内容被回显到表格而不是创建一个包含内容的表格时，它会创建多个表格。

我明白了：

表1：

• header1 -------- header2
• 成就1 - 成就 时间

表2：

• header1 -------- header2
• achievement2 - 成就时间

我期待：

表1

• header1 -------- header2
• achievement1 - 成就时间
• achievement2 - 成就时间

我已经尝试过 array_merge，我尝试过将成就 ID 设置为键，我什至尝试过多个 foreach 语句，但这似乎会消除重复项以及创建额外的表。 如果有人不介意告诉我我做错了什么，我将不胜感激。

<?php
// Define cache file
$cache_file = "cache.txt";

// Cache file is less than thirty minutes old.
if (file_exists($cache_file) && (filemtime($cache_file) > (time() - 60 * 30  ))) {

// Don't bother refreshing, just use the file as-is.
$file = file_get_contents($cache_file);

// Our cache is out-of-date, so load the data from our remote server,
// and also save it over our cache for next time.
} else {
$file = file_get_contents('http://eu.battle.net/api/wow/guild/chamber-of-aspects/requiem%20paradisum?fields=achievements');
file_put_contents($cache_file, $file, LOCK_EX);
}

// Decode cache file
$achie = json_decode($file);

// Seperate achievements and timestamps as variables
$achiachi = ($achie->achievements->achievementsCompleted);
$achitime = ($achie->achievements->achievementsCompletedTimestamp);
foreach(array_combine($achiachi, $achitime) as $f => $n){

// Combine achievement number into Link for wowhead script
$achilink = ("http://www.wowhead.com/achievement=". $f);

// Sort out time formatting
$unix = ($n);
$not_unix = $unix / 1000;
$date = date("F d Y @ h:i A", $not_unix);

//Print into table
echo "
<table align=center class=mytable cellpadding=8 style=font-family:verdana;font-size:8pt;color:white;>
<tr>
        <th>Achievement</th><th>Timestamp</th>
<tr>
      <td><a href=\"$achilink\" rel=\"item=$achiachi\"></a></td>
      <td>$date</td>
</tr>
</table>
";
}
?>

Answer 1

为什么不把table和th标签放到循环之外呢？：

echo "<table align=center class=mytable cellpadding=8 style=font-family:verdana;font-size:8pt;color:white;>";
echo "<tr><th>Achievement</th><th>Timestamp</th></tr>";
foreach(array_combine($achiachi, $achitime) as $f => $n){

// Combine achievement number into Link for wowhead script
$achilink = ("http://www.wowhead.com/achievement=". $f);

// Sort out time formatting
$unix = ($n);
$not_unix = $unix / 1000;
$date = date("F d Y @ h:i A", $not_unix);

//Print into table
echo "<tr>
      <td><a href=\"$achilink\" rel=\"item=$achiachi\"></a></td>
      <td>$date</td>
</tr>";
}
echo "</table>";

我认为您必须在 for 循环之外回显 and first for 标头
