我有textfile“animals.txt”,它看起来像:
mammals cat, fox, horse
birds parrot, eagle
reptiles snake, crocodile
列由\t
和,
分隔。
如何将其显示为嵌套列表,如下所示:
<ul>
<li>mammals
<ul>
<li>cat</li>
<li>fox</li>
<li>horse</li>
</ul>
</li>
<li>birds
<ul>
<li>parrot</li>
<li>eagle</li>
</ul>
</li>
<li>reptiles
<ul>
<li>snake</li>
<li>crocodile</li>
</ul>
</li>
</ul>
我现在拥有的:
$data = file_get_contents('animals.txt');
$array = explode("\t", $data);
foreach ($array as $line) {
echo "<li>$line</li>";
}
答案 0 :(得分:0)
这会奏效。爆炸每一行,然后打印相应的ul和li:
$file = file('animals.txt');
print '<ul>';
foreach ($file as $line) {
// 1) exploding by "\t" and then again by ","
$values = explode("\t", $line);
$list = explode(',', $values[1]);
// 2) show the first name in the line
print '<li>';
print $values[0];
print '<ul>';
// 3) followed by a nested ul containing the comma-separated values
foreach ($list as $sub_item) {
print '<li>' . $sub_item . '</li>';
}
print '</ul>';
print '</li>';
}
print '</ul>';
答案 1 :(得分:-1)
这会奏效。第一步是分隔制表符分隔的值(哺乳动物猫,狐狸,马)和第二步(foreach循环)是获得逗号分隔值(猫,狐狸,马)。最后,我们在列表中打印单个值(猫狐等)。

var attForm = ""
val bodyPart = data.fields(0)
data.fields foreach {
bodyPart => println(bodyPart.headers.find(h=> h.is("content-disposition")).get.value)
}
}
