这是可行的，但似乎不是正确的编码方式
我不知道该怎么办
foreach ($data as $tag) {
if ($tag==1) echo "<a onclick=\"window.location.href='/buscatag/1'\">Coméda</a>,\n";
if ($tag==2) echo "<a onclick=\"window.location.href='/buscatag/2'\">Ecchi</a>,\n";
if ($tag==3) echo "<a onclick=\"window.location.href='/buscatag/3'\">Peitos grandes</a>,\n";
if ($tag==4) echo "<a onclick=\"window.location.href='/buscatag/4'\">Nudez</a>,\n";
if ($tag==5) echo "<a onclick=\"window.location.href='/buscatag/5'\">Seinen</a>,\n";
if ($tag==6) echo "<a onclick=\"window.location.href='/buscatag/6'\">Violência<a/>,\n";
if ($tag==7) echo "<a onclick=\"window.location.href='/buscatag/7'\">Vida Cotidiana</a>,\n";
if ($tag==8) echo "<a onclick=\"window.location.href='/buscatag/8'\">Harém</>,\n";
if ($tag==9) echo "<a onclick=\"window.location.href='/buscatag/9'\">Ação</a>,\n";
if ($tag==10) echo "<a onclick=\"window.location.href='/buscatag/10'\">Shonen</a>,\n";
if ($tag==11) echo "<a onclick=\"window.location.href='/buscatag/11'\">Super Poderes</a>,\n";
if ($tag==12) echo "<a onclick=\"window.location.href='/buscatag/12'\">Aventura</a>,\n";
if ($tag==13) echo "<a onclick=\"window.location.href='/buscatag/13'\">Fantasia</a>,\n";
if ($tag==14) echo "<a onclick=\"window.location.href='/buscatag/14'\">Loli</a>,\n";
}

// Define $lookup as
$lookup = [1 => 'Coméda', 2 => 'Ecchi',]; // etc
// Note the relation between key and value
foreach ($data as $tag) {
echo "<a onclick=\"window.location.href='/buscatag/{$tag}'\">" . $lookup[$tag] . "</a>,\n";
}

在代码中，您可以立即将数字放入标签
尝试
$names = ['name1', 'name2'...];
foreach ($data as $tag) {
echo sprintf("<a onclick=\"window.location.href='/buscatag/%s'\">%s</a>,\n", $tag, $names[$tag-1]);
}
