Question

我的阵列是这样的。那么如何用php访问名称，值？

Array(
[0] => Array
    (
        [name] => subject
        [value] => คอมพิวเตอร์ ม.3
    )

[1] => Array
    (
        [name] => subject_code
        [value] => ง33101
    )

[2] => Array
    (
        [name] => subject_hour
        [value] => 2
    )

[3] => Array
    (
        [name] => semester
        [value] => 1
    )

[4] => Array
    (
        [name] => level
        [value] => 3
    )

[5] => Array
    (
        [name] => classroom
        [value] => 301
    )

[6] => Array
    (
        [name] => classroom
        [value] => 302
    )
)

我已经尝试过FOREACH循环遍历数组并且它完成了这项工作，但是我怎样才能让他们的名字和值在以后使用？我的FOREACH代码：

foreach($objects AS $values){
    foreach($values as $value){
        echo $value.'<br/>';
    }
}

Answer 1

假设您的数组是$array：

foreach($array as $item){
       $name = $item['name'];  //extract name
       $value = $item['value'];  //extract value
       echo $name.'  '.$value.'</br>';
}

Answer 2

要获取索引/键，只需将其命名为：

foreach($collection as $key => $value)
    print($key . ' = ' . $value . '\n');

Answer 3

迭代$对象以获取值和名称;

foreach($objects as $value){
    echo "Name: ".$value['name'];
    echo " - Value: ".$value['value'];
    echo "<br/>";
}
