如何从php多维数组中获取每一列数据?
如何将php多维中的每一列数据转化为单列数组?
how get each single column data from php multidimensional into single column array?
like $_test = = array(
array(
'id' => 1001,
'first_name' => 'kalpesh',
'last_name' => 'gamit',
),
array(
'id' => 1002,
'first_name' => 'kartik',
'last_name' => 'patel',
),
array(
'id' => 2002,
'first_name' => 'smith',
'last_name' => 'Jones',
),
array(
'id' => 4004,
'first_name' => 'patel',
'last_name' => 'Doe',
)
);
只需要像 id 或 first_name 这样的结果，而不需要像 while、foreach、for 等循环
want result like id OR first_name only without use loop like while, foreach, for etc
Array
(
[0] => 1001
[1] => 1002
[2] => 2002
[3] => 4004
)
推荐答案
像下面一样更新你的脚本并检查它，但它只能在 PHP 5.5 高于版本......
update your script like below and check it please but it will work only in PHP 5.5 greater than version only...
$_test = = array(
array(
'id' => 1001,
'first_name' => 'kalpesh',
'last_name' => 'gamit',
),
array(
'id' => 1002,
'first_name' => 'kartik',
'last_name' => 'patel',
),
array(
'id' => 2002,
'first_name' => 'smith',
'last_name' => 'Jones',
),
array(
'id' => 4004,
'first_name' => 'patel',
'last_name' => 'Doe',
)
);
$ids_only = array_column($records, 'id');
print_r($ids_only);
ID 的结果
Array
(
[0] => 1001
[1] => 1002
[2] => 2002
[3] => 4004
)
first_name 的结果
Results for first_name
$first_name = array_column($records, 'id');
print_r($first_name);
Array
(
[0] => Kalpesh
[1] => kartik
[2] => smith
[3] => patel
)
运行上面的php脚本，请检查....
