如何在php中显示具有特定条件的数组对象

Question

我想在html:中进行如下选择显示

<div name="option_a">
<p>result for option_a</p>
<img src="option_a_image"></img>
</div>
<div name="option_b">
<p>result for option_b</p>
<img src="option_b_image"></img>
</div>
<div name="option_c">
<p>result for option_c</p>
<img src="option_c_image"></img>
</div>
<div name="option_d">
<p>result for option_d</p>
<img src="option_d_image"></img>
</div>

使用这个数组：

Array
(
[0] => stdClass Object
(
[option_a] => its option a
[option_a_image] => its an image for option a
[option_b] => its option b
[option_b_image] => its an image for option b
[option_c] => its option c
[option_c_image] => its an image for option c
[option_d] => its option d
[option_d_image] => its an image for option d
)
[1] => stdClass Object
(
[option_a] => its option a
[option_a_image] => its an image for option a
[option_b] => its option b
[option_b_image] => its an image for option b
[option_c] => its option c
[option_c_image] => its an image for option c
[option_d] => its option d
[option_d_image] => its an image for option d
)
[2] => stdClass Object
(
[option_a] => its option a
[option_a_image] => its an image for option a
[option_b] => its option b
[option_b_image] => its an image for option b
[option_c] => its option c
[option_c_image] => its an image for option c
[option_d] => its option d
[option_d_image] => its an image for option d
)
)

但我想用循环来使它更简洁。我尝试过以下几种：

<?php foreach($array[0] as $type=>$value ){
if(strpos($type,'option_') !== false){ ?>           
<div class="card mb-3" style="width: 98%; margin: auto">
<div class="card-body">

<label ><input type='radio' name='r1' tabindex='5'> <span><?php echo $value ?></span></label> <br>        

</div>
</div>
<?php } } ?>

但是像这样的循环不能产生我想要创建的视图。那么，我如何让循环形成我想要产生的结果呢？

谢谢

它应该适合您：

$array[0] = [
"option_a"       => "its option a",
"option_a_image" => "its an image for option a",
"option_b"       => "its option b",
"option_b_image" => "its an image for option b",
"option_c"       => "its option c",
"option_c_image" => "its an image for option c",
"option_d"       => "its option d",
"option_d_image" => "its an image for option d"
];
$thisElementIsOption = true;
$option = [];
foreach($array[0] as $type => $value) {
if(strpos($type, 'option_') !== false) {
if ($thisElementIsOption) {
$option['name'] = $type;
} else {
$option['image'] = $type;
$name = $option['name'];
$image = $option['image'];
echo "<div name='$name'><p>result for $name</p><img src='$image'></img></div>".PHP_EOL;
$option = [];
}
$thisElementIsOption = !$thisElementIsOption;
}
}

输出

<div name='option_a'><p>result for option_a</p><img src='option_a_image'></img></div>
<div name='option_b'><p>result for option_b</p><img src='option_b_image'></img></div>
<div name='option_c'><p>result for option_c</p><img src='option_c_image'></img></div>
<div name='option_d'><p>result for option_d</p><img src='option_d_image'></img></div>

在这个解决方案中，我使用$thisElementIsOption作为标志变量，生成一个数组$option，并使html输出交叉
