充分利用数组一个特定的值 [英] Getting a specific value from array

问题描述

我对mysql的这个查询，我得到这个数组的print_r（）：

I have this query on mysql, and i'm getting this array with print_r():

$data = Array ( [2] => Array ( [0] => Array ( [sale_order_value_id] => 3 [sale_order_id] => 2 [name] => Comprobante Fiscal [value] => Consumidor Final [price] => 0.0000 ) [1] => Array ( [sale_order_value_id] => 4 [sale_order_id] => 2 [name] => RNC / Cédula [value] => 00111936266 [price] => 0.0000 ) ) )

我想只提取【名称】从$每个输入数据，我都试过爆炸（）来分隔值，但它不能帮助。

I want to extract just the [name] from $data for each input, i have tried explode() to separate the values but that does not help.

推荐答案

下面是做一个适当的方式：

Here is a proper way to do it :

示例：

<?php
// Array representing a possible record set returned from a database
$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',
    )
);

$first_names = array_column($records, 'first_name');
print_r($first_names);
?>

OUTPUT：

Array
(
    [0] => John
    [1] => Sally
    [2] => Jane
    [3] => Peter
)

和是在你的情况下，可以也是这样的做，因为它很简单：

And Yes in your case it can be done like this way too as it is easy :

您code：

<?php
$data = array( 2 => array( 0 => array('name' => "John")));
//You can simply print the name column value like this
echo $data[2][0]["name"];
?>

您code输出：

John
