如何使用PHP合并数组?

日期数组

array(
   0 => array("date_1" => "06-09-2010"),
   1 => array("date_2" => "07-09-2010"),
   2 => array("date_3" => "08-09-2010")
)

日数组

array(
   0 => array("day_1" => "Monday"),
   1 => array("day_2" => "Tuesday"),
   2 => array("day_3" => "Wednesday")

期间数组

array(
   0 =>  array("period_1" => "1"),
   1 =>  array("period_2" => "1"),
   2 =>  array("period_3" => "1")
) 

如何更改/合并数组以使数组成为这样的?

array 0 = date_1,day_1, period_1
array 1 = date_2,day_2, period_2
array 2 = date_3,day_3, period_3

使用数组合并将返回类似这样的内容

array(
   0 => array("date_1" => "06-09-2010"),
   1 => array("date_2" => "07-09-2010"),
   2 => array("date_3" => "08-09-2010"),
   3 => array("period_1" => "1"),
   4 => array("period_2" => "1"), 
   5 => array("period_3" => "1"),  
   6 => array("day_1" => "Monday"),
   7 => array("day_2" => "Tuesday"),
   8 => array("day_3" => "Wednesday")
)

使用此功能可以解决问题。谢谢 Codaddict!

$date = array(
array('date_1'=>"06-09-2010"),
array('date_2'=>"07-09-2010"));

$day = array(
    array("day_1"=>"Monday"),
    array("day_2"=>"Tuesday")
);

$period = array(
    array("period_1"=>1),
    array("period_2"=>2)
);

$result = array(); 
for($i=0;$i<count($date);$i++) {
    array_push($result,array($data[$i],$day[$i],$period[$i]));
}
var_dump($result);

您可以尝试:

$data = array(
    array('date_1'=>"06-09-2010"),
    array('date_2'=>"07-09-2010")
);
$day = array(
    array("day_1"=>"Monday"),
    array("day_2"=>"Tuesday")
);
$period = array(
    array("period_1"=>1),
    array("period_2"=>2)
);

$result = array(); 

// assuming all arrays are of same size.
for($i=0;$i<count($data);$i++) {
    array_push($result,array($data[$i],$day[$i],$period[$i]));
}
var_dump($result);

如果您的3个数组相同长度并使用相同的键编制索引,则可以运行此命令:

$merged = array();
//iterate on the keys
foreach(array_keys($date_array) as $index)
  //merge the sub arrays
  $merged[$index] = array_merge(array(), $date_array[$index], $day_array[$index], $period_array[$index]);
}

编辑:如果您的密钥不是数字,则可以使用array_merge_recursive来获得所需内容。如果您想依赖基本语言函数,这可能是一个更干净的选项。 http://www.php.net/manual/en/function.array-merge-recursive.php
