我有一个数组数组,具有以下结构:
array(array('page' => 'page1', 'name' => 'pagename1')
array('page' => 'page2', 'name' => 'pagename2')
array('page' => 'page3', 'name' => 'pagename3'))
是否有内置函数将返回一个只包含'name'键值的新数组？所以我得到:
array('pagename1', 'pagename2', 'pagename3')
实现数据库查询后,我将获得下面的多维数组.
二维数组
Array
(
[0] => Array
(
[t1] => test1
)
[1] => Array
(
[t2] => test2
)
[2] => Array
(
[t3] => test3
)
[3] => Array
(
[t4] => test4
)
[4] => Array
(
[t5] => test5
)
)
但我想将其转换为单维数组,如下面的格式.
一维数组
Array (
t1 => test1
t2 => test2
t3 => test3
t4 => test4
t5 => test5
)
请帮我这样做
我有以下数组,
Array
(
[14289] => Array
(
[0] => Ability||STROKE CLINIC,Session||Session #3: Tues June 28th - Fri July 8th (9-2:00PM),Time||#1 only: 2pm,child1||FC
[1] => Ability||N/S++,Session||Session #3: Tues June 28th - Fri July 8th (9-2:00PM),Time||#1 only: 2pm,child2||SC
[2] => Ability||B-,Session||Session #3: Tues June 28th - Fri July 8th (9-2:00PM),Time||#1 only: 2pm,child3||TC
)
[14279] => Array
(
[0] => Ability||STROKE CLINIC,Session||Session #1: Tues May 31st - Fri June 10th (1-5:30PM),Time||#1 only: 1pm,child1||FC
[1] => Ability||N/S++,Session||Session #1: Tues May 31st - Fri June …我有一个动态多维数组，我想将其转换为字符串。这是一个例子：
Array
(
[data] => check
[test1] => Array
(
[data] => Hello
)
[test2] => Array
(
[data] => world
)
[test3] => Array
(
[data] => bar
[tst] => Array
(
[data] => Lorem
[bar] => Array
(
[data] => doller
[foo] => Array
(
[data] => sit
)
)
)
)
[test4] => Array
(
[data] => HELLO
[tst] => Array
(
[data] => ipsum
[bar] => Array
(
[data] => Lorem
)
)
)
)
字符串的例子是： …
我有一个像这样的 PHP 数组：
$array['my_data']['value'] = 'some value';
$array['my_own_data']['value'] = 'another value';
$array['different_data']['value'] = 'another value';
我需要在 PHP 等中使用 array_merge。问题是第一级密钥的数量是未知的。可能是 150 个项目，我不知道。
由于未知数量的键，这对我不起作用：
array_merge($array['my_data'], $array['my_own_data'], $array['different_data']);
我需要一个循环还是有什么花哨的东西？
