[英]fetch value from array within array within array
I have trouble understanding arrays. 我在理解数组时遇到麻烦。 For example, I got the following data.
例如,我得到了以下数据。
array(
label=> person1
start=> 2014-10-10
end=> 2014-10-11
class=> annual
)
array(
label=> person2
start=> 2014-10-08
end=> 2014-10-08
class=> sick
)
array(
label=> person1
start=> 2014-10-01
end=> 2014-10-03
class=> sick
)
array(
label=> person3
start=> 2014-10-20
end=> 2014-10-20
class=> annual
)
array(
label=> person1
start=> 2014-10-29
end=> 2014-10-29
class=> compassionate
)
And I want to arrange it this way 我想这样安排
array(
[person1]=>array(
array(
start=> 2014-10-10
end=> 2014-10-11
class=> annual),
array(
start=> 2014-10-01
end=> 2014-10-03
class=> sick),
array(
start=> 2014-10-29
end=> 2014-10-29
class=> compassionate),
),
[person2]=>array(
start=> 2014-10-08
end=> 2014-10-08
class=> sick),
[person3]=>array(
start=> 2014-10-20
end=> 2014-10-20
class=> annual)
)
My requirement is to display the data with same label in the same row. 我的要求是在同一行中显示带有相同标签的数据。 This is the code I used but it does not works at all.
这是我使用的代码,但是根本不起作用。
var $blocks = array();
var $data = array();
var $blocksByLabel = array();
global $blocksByLabel;
global $blocks;
foreach($this->data as $d) {
foreach ($this->blocks as $block) {
$label = $block->$d['label'];
if (!array_key_exists($d['label'], $blocksByLabel)){
$blocksByLabel[$block->label] = array();
}
array_push($blocksByLabel[$block->label], $blocks);
}
$this->blocks[] = array(
'label' => $d['label'],
'start' => $start = strtotime($d['start']),
'end' => $end = strtotime($d['end']),
'class' => @$d['class']
);
use this: 用这个:
$old_array
is the source array and $new_array
is the rearanged array $old_array
是源数组,而$new_array
是重新排列的数组
foreach($old_array as $r) {
$new_array[$r['label']][] = array("start" => $r['start'],
"end" => $r['end'],
"class" => $r['class']);
}
this should arrange your array the way you want.. and you should rename the old_array and new_array based on your variable names.. 这应该按照您想要的方式排列数组。并且您应该根据变量名重命名old_array和new_array。
ADDED RUNNING PROGRAM for further clarification 附加的运行程序,以进一步说明
here is my running code: 这是我的运行代码:
<?php
$old_array[] = array("label" => "person1", "start" => "2014-10-10", "end" => "2014-10-11", "class" => "anual");
$old_array[] = array("label" => "person2", "start" => "2014-10-08", "end" => "2014-10-08", "class" => "sick");
$old_array[] = array("label" => "person1", "start" => "2014-10-01", "end" => "2014-10-03", "class" => "sick");
$old_array[] = array("label" => "person3", "start" => "2014-10-20", "end" => "2014-10-20", "class" => "anual");
$old_array[] = array("label" => "person1", "start" => "2014-10-29", "end" => "2014-10-29", "class" => "compassionate");
foreach($old_array as $r) {
$new_array[$r['label']][] = array("start" => $r['start'],
"end" => $r['end'],
"class" => $r['class']);
}
echo "<pre>";
print_r($new_array);
echo "</pre>";
?>
after execution, the output should be: 执行后,输出应为:
Array
(
[person1] => Array
(
[0] => Array
(
[start] => 2014-10-10
[end] => 2014-10-11
[class] => anual
)
[1] => Array
(
[start] => 2014-10-01
[end] => 2014-10-03
[class] => sick
)
[2] => Array
(
[start] => 2014-10-29
[end] => 2014-10-29
[class] => compassionate
)
)
[person2] => Array
(
[0] => Array
(
[start] => 2014-10-08
[end] => 2014-10-08
[class] => sick
)
)
[person3] => Array
(
[0] => Array
(
[start] => 2014-10-20
[end] => 2014-10-20
[class] => anual
)
)
)
the code for rearranging the array is working fine.. please check your $this->data
variable through var_dump($this->data)
to check the variable's content.. (if the source array doesn't have value, of course the result would have no value either).. 为重新安排数组的代码工作正常。请检查您的
$this->data
通过可变var_dump($this->data)
来检查变量的内容。(如果源阵列不具有价值,当然结果也将没有任何价值)。
hope this helps.. 希望这可以帮助..
