你好，PHP开发人员/程序员专家，我需要你的帮助，请。。。 我正在尝试循环数组字符串关联的数组内部，对于每一个循环的问题都是冗余数据显示。
下面是数组中的代码数据:
$attr_xyz = array(
'child_id' => array('id_a','id_b','id_c'),
'child_class' => array('class_a','class_b','class_c'),
'labels' => array('label_a','label_b','label_c'),
);
我正在做的是:
$get_attr_label_id = [];
foreach ($attr_xyz['child_id'] as $child_id)
{
$get_attr_label_id[] = $child_id;
}
$get_child_id = implode(" ", $get_attr_label_id);
$get_attr_label_ = [];
foreach ($attr_xyz['labels'] as $labels)
{
$get_attr_label_[] = $labels;
}
$get_child_labels = implode(" ", $get_attr_label_);
应为:输出:
<div id="id_a">
<lable>$label_a</lable>
</div>
<div id="id_b">
<lable>$label_a</lable>
</div>
<div id="id_c">
<lable>$label_a</lable>
</div>
但事实是:
<lable>$label_a</lable>
<div id="id_a" id="id_b" id="id_c"></div>
<div id="id_a" id="id_b" id="id_c"></div>
<div id="id_a" id="id_b" id="id_c"></div>
<lable>$label_b</lable>
<div id="id_a" id="id_b" id="id_c"></div>
<div id="id_a" id="id_b" id="id_c"></div>
<div id="id_a" id="id_b" id="id_c"></div>
<lable>$label_c</lable>
<div id="id_a" id="id_b" id="id_c"></div>
<div id="id_a" id="id_b" id="id_c"></div>
<div id="id_a" id="id_b" id="id_c"></div>
请我帮忙，非常感谢您提前！ :）
试试这个
<?php
$cntr = count($attr_xyz['child_id']) - 1;
for($x == 0; $x <= $cntr; $x++)
{
$child_id = $attr_xyz['child_id'][$x];
$label = $attr_xyz['labels'][$x];
//Print your html here
echo "<div id=\"$child_id\">\n
<label>$label</label>\n
</div>\n\n";
}
?>
没有理由遍历数组并创建新数组。 原来的数组已经有了很好的结构。
这应该可以做到:
$attr_xyz = [
'child_id' => array('id_a','id_b','id_c'),
'child_class' => array('class_a','class_b','class_c'),
'labels' => array('label_a','label_b','label_c'),
];
foreach ($attr_xyz['child_id'] as $key => $id) {
?>
<div id="<?= $id ?>">
<lable><?= $attr_xyz['labels'][$key] ?></lable>
</div>
<?php
}
