如何从PHP中的多维数组打印数组特定值

Question

以下是我打印的数组：-

我只需要循环中数组中的product_image

 Array
(
    [0] => Array
        (
            [product_option_id] => 247
            [product_id] => 66
            [product_option_value] => Array
                (
                    [0] => Array
                        (
                            [product_option_value_id] => 42
                            [color_product_id] => 54
                            [name] => Pink
                            [product_image] => catalog/demo/teddy/03.jpg
                            [image] => http://192.168.15.9/Kids_stores/image/cache/catalog/axalta-ral-3015-light-pink-polyester-30-matt-powder-coating-20kg-box--1447-p-50x50.jpg
                            [price] => 
                            [price_prefix] => +
                        )

                    [1] => Array
                        (
                            [product_option_value_id] => 41
                            [color_product_id] => 67
                            [name] => Light Brown
                            [product_image] => catalog/Teddies/12-Baby-teddy/05.jpg
                            [image] => http://192.168.15.9/Kids_stores/image/cache/catalog/option-color/light_brown-50x50.jpg
                            [price] => 
                            [price_prefix] => +
                        )

                    [2] => Array
                        (
                            [product_option_value_id] => 43
                            [color_product_id] => 68
                            [name] => Cream 
                            [product_image] => catalog/Teddies/12-Baby-teddy/11.jpg
                            [image] => http://192.168.15.9/Kids_stores/image/cache/catalog/option-color/cream-images-50x50.jpg
                            [price] => 
                            [price_prefix] => +
                        )

                )

            [option_id] => 5
            [name] => COLOR
            [type] => image
            [value] => 
            [required] => 0
        )

)

Answer 1

尝试这个，

foreach($array as $val)
{ 
    echo $val['product_image'];
}

Answer 2

您可以将数组array_column设置为这样

$records = array (
     array ( 
              // your array
           )
);
$variable = array_column($records, 'image');
echo $variable;

Answer 3

您编辑的输入的解决方案：-

$image_array = array();

foreach ($your_array as $arr){
   $image_array[] = array_column($arr['product_option_value'],'product_image');
}

输出： -https : //eval.in/657966

Answer 4

    <?php $samples=$data['options'][0][product_option_value]; 



    $product_image = array_column($samples, 'product_image');
    echo'<pre>'; print_r($product_image );  

    ?>

Answer 5

解决方案一：

<?php
$req_image=array();
$req_image[] = array_column($resultant_array, 'product_image');   
print_r($req_image); // This will print all the images that are grouped under the array().
?>

例：

下面是PHP代码以及可以使用array_column()获得的示例输出。

PHP：

<?php
$records = array(
    array(
        'id' => 2135,
        'first_name' => 'John',
        'last_name' => 'Doe'
    ),
    array(
        'id' => 3245,
        'first_name' => 'Sally',
        'last_name' => 'Smith'
    ),
    array(
        'id' => 5342,
        'first_name' => 'Jane',
        'last_name' => 'Jones'
    ),
    array(
        'id' => 5623,
        'first_name' => 'Peter',
        'last_name' => 'Doe'
    )
);

$lastNames = array_column($records, 'last_name', 'id');

输出：

如果我们在$lastNames上调用print_r() ，您将看到一个结果数组，看起来像这样：

Array
(
    [2135] => Doe
    [3245] => Smith
    [5342] => Jones
    [5623] => Doe
)

解决方案二：（ 最后根据要求 ）

您可以在foreach中单独迭代单个键值，以便获得所需的必需参数。

foreach($resultant_array as $single_array)
{
  foreach($single_array['product_option_value'] as $inner_array)
  {
    echo $inner_array['product_image']; // This will print the u=mage name that you need.
  }
}

Answer 6

foreach($array as $key => $val){
  if($key == 'product_image'){
    echo "<img src='".$val."' />";
  }
}

尝试

Answer 7

您必须先获取内部数组：

foreach($array[product_option_value] as $val)
{ 
    echo $val['product_image'];
}

Answer 8

如果您需要一个指定的键，并且希望对数组结构的假设最少，请使用array_walk_recursive这样的

 $result = []; 
 array_walk_recursive($input,function ($value,$key) use (&$result) {
           if ( 'product_image' == $key) {
               $result[] = $value;
           }
 });
