获取同一子数组中的值[PHP]

我有以下数组：

array(2) {
  [0]=>
  array(2) {
    ["EAN"]=>
    string(13) "1234567890123"
    ["Price"]=>
    string(5) "99.00"
  }
  [1]=>
  array(2) {
    ["EAN"]=>
    string(13) "2234567890123"
    ["Price"]=>
    string(6) "199.00"
  }
}

我想：

1） 使用EAN值查找其中一个子数组

2） 并返回此特定EAN的相关价格

例如，函数getPrice（'2234567890123'）应该返回199.00

getPrice函数的代码应该是什么？

您可以使用以下代码：

<?php
$array = array(
"0"=>
    array(
        "EAN"=>"1234567890123",
        "Price"=>"99.00"
    ),
"1"=>
    array (
        "EAN"=>"2234567890123",
        "Price"=>"199.00"
    )
);

$key = array_search('1234567890123', array_column($array, 'EAN'));
echo $array[$key]['Price'];
?>

---

您可以使用此代码实现所需的输出

//getPrice method which accepts two parameters $products array and $ean number
function getPrice($products,$ean){
    //iterate $products array to get its elements
    foreach($products as $product){
      //if $procust arrays element EAN matches with $ean number we provide
      if($product['EAN'] == $ean){
      //than return its price
        return $product['Price'];
     }
  }
}


//products array
$products = array(
    '0'=>
     array(
       'EAN'=>'1234567890123',
       'Price'=>'99.00'
     ),
    '1'=>
    array (
      'EAN'=>'2234567890123',
      'Price'=>'199.00'
   )
 );

//EAN value which you need to pass and get its corresponding price
$ean = '2234567890123'; 

//call getPrice function and save the return output value in a $price variable which you can use anywhere
$price =  getPrice($products, $ean);

//print the value by echo $price to verify the required output.
echo $price;

我们不会为您编写代码，告诉我们您尝试了什么以及遇到了什么错误。创建一个循环，查找

EAN

的值，然后测试您的条件（如果匹配），然后存储

价格。
//getPrice method which accepts two parameters $products array and $ean number
function getPrice($products,$ean){
    //iterate $products array to get its elements
    foreach($products as $product){
      //if $procust arrays element EAN matches with $ean number we provide
      if($product['EAN'] == $ean){
      //than return its price
        return $product['Price'];
     }
  }
}


//products array
$products = array(
    '0'=>
     array(
       'EAN'=>'1234567890123',
       'Price'=>'99.00'
     ),
    '1'=>
    array (
      'EAN'=>'2234567890123',
      'Price'=>'199.00'
   )
 );

//EAN value which you need to pass and get its corresponding price
$ean = '2234567890123'; 

//call getPrice function and save the return output value in a $price variable which you can use anywhere
$price =  getPrice($products, $ean);

//print the value by echo $price to verify the required output.
echo $price;
