Array within array as single associative array - php

Question

I am having array within array values as below.
Array
(
[0] => Array
(
[0] => Array
(
[Floor] => Floor-1
)
[1] => Array
(
[Flat] => Flat A2
)
[2] => Array
(
[Area] => Balcony,
)
)
)
I need to make it as single associative array as below.
Array
(
[0] => Array
(
[Floor] => Floor-1
[Flat] => Flat A2
[Area] => Balcony,
)
)
How can i do this ?

Answer 1

This example should help you.
<?php
$arr = array(
array(
'floor'=>'Floor-1'
),
array(
'Flat'=>'Flat A2'
),
array(
'Area'=>'Balcony,'
),
);
$final_array = array();
foreach ($arr as $arr1) {
foreach ($arr1 as $key => $value) {
$final_array[$key] = $value;
}
}
?>
Output will be
Array
(
[floor] => Floor-1
[Flat] => Flat A2
[Area] => Balcony,
)
Here we have created an empty array called as $final_array we will append this array by using foreach loop.
Remember, if you have a same array key then the last value will overwrite like below.
<?php
$arr = array(
array(
'floor'=>'Floor-1',
'floor'=>'Floor-2',
),
array(
'Flat'=>'Flat A2'
),
array(
'Area'=>'Balcony,'
),
array(
'Area'=>'Balcony2,'
),
);
$final_array = array();
foreach ($arr as $arr1) {
foreach ($arr1 as $key => $value) {
$final_array[$key] = $value;
}
}
?>
Now, output will be
Array
(
[floor] => Floor-2
[Flat] => Flat A2
[Area] => Balcony2,
)

Answer 2

<?php
$array = [
[
[
'foo' => 'big'
],
[
'bar' => 'fat'
],
[
'baz' => 'mamma'
]
]
];
$merged[0] = array_reduce($array[0], function($carry, $item) {
return array_merge((array) $carry, $item);
});
var_export($merged);
Output:
array (
0 =>
array (
'foo' => 'big',
'bar' => 'fat',
'baz' => 'mamma',
),
)

Answer 3

This single line code is enough to do this
$newArr = call_user_func_array('array_merge',$dataArr); ///where $dataArr is your array..
call_user_func_array will call a callback function with array of parameters and array_merge will merge all these parameters in single array read more about call_user_func_array() and array_merge()
Example code:
<?php
$dataArr = array(
array(
'Floor'=>'Floor-1'
),
array(
'Flat'=>'Flat A2'
),
array(
'Area'=>'Balcony,'
),
);
$newArr = call_user_func_array('array_merge',$dataArr);
echo "<pre>"; print_r($newArr);
?>
This will give you :
Array
(
[Floor] => Floor-1
[Flat] => Flat A2
[Area] => Balcony,
)
