I am developing Tree View in php, how to connect my php array code in html UI designs.
My Php code is:
<?php
//if order by parentid, id
$arr = array(
array('id'=>100, 'parentid'=>0, 'name'=>'first'),
array('id'=>101, 'parentid'=>100, 'name'=>'second'),
array('id'=>102, 'parentid'=>100, 'name'=>'third'),
array('id'=>103, 'parentid'=>100, 'name'=>'fourth'),
array('id'=>104, 'parentid'=>101, 'name'=>'five'),
array('id'=>105, 'parentid'=>102, 'name'=>'six'),
array('id'=>106, 'parentid'=>103, 'name'=>'seven'),
array('id'=>107, 'parentid'=>101, 'name'=>'eight'),
array('id'=>108, 'parentid'=>101, 'name'=>'nine'),
array('id'=>109, 'parentid'=>102, 'name'=>'ten'),
);
$arr_tree = array();
$arr_tmp = array();
foreach ($arr as $item) {
$parentid = $item['parentid'];
$id = $item['id'];
if ($parentid == 0)
{
$arr_tree[$id] = $item;
$arr_tmp[$id] = &$arr_tree[$id];
}
else
{
if (!empty($arr_tmp[$parentid]))
{
$arr_tmp[$parentid]['children'][$id] = $item;
$arr_tmp[$id] = &$arr_tmp[$parentid]['children'][$id];
}
}
}
unset($arr_tmp);
echo '<pre>'; print_r($arr_tree); echo "</pre>";
?>
and my html UI code
<div class="tree">
<ul>
<li>
<a href="#"></a>
<ul>
<li><a href="#"></a>
<ul>
<li><a href="#"></a></li>
<li><a href="#"></a></li>
<li><a href="#"></a></li>
</ul>
</li>
<li><a href="#"></a>

<li><a href="#"></a></li>
<li><a href="#"></a></li>
</ul>
</li>
<li><a href="#"></a>
<ul>
<li><a href="#"></a></li>
<li><a href="#"></a></li>
<li><a href="#"></a></li>
</ul>
</li>
</ul>
</li>
</ul>
</div>
and style sheet code

How to integrate my php code in html UI
my desired result is like this image
We can use a "real" tree in php code and that makes the things much easier.
class Branch {
public $branches = [];
public $name;
public function __construct($name) {
$this->name = $name;
}
public function to_html() {
$str = '<li><a href="#">' . $this->name . "</a>\n";
if (!empty($this->branches)) {
$str .= '<ul>';
foreach ($this->branches as $branch) {
$str .= $branch->to_html();
}
$str .= '</ul>';
}
$str .= "</li>\n";
return $str;
}
}
$tree = new Branch("first");
$tree->branches[] = new Branch("second");
$tree->branches[] = new Branch("third");
$tree->branches[] = new Branch("fourth");
$tree->branches[0]->branches[] = new Branch("five");
$tree->branches[0]->branches[] = new Branch("eight");
$tree->branches[0]->branches[] = new Branch("nine");
$tree->branches[1]->branches[] = new Branch("six");
$tree->branches[1]->branches[] = new Branch("ten");
$tree->branches[2]->branches[] = new Branch("seven");
$html = $tree->to_html();
The output html will be
由于php是html可嵌入的代码,因此您可以在html中的任何位置使用php,例如从头到尾再到正文等等。
