I want to merge two dimensional arrays - php

Question

Let me describe you the scenario
I have got two arrays one with second column as 0
and another array with second column with some value,
first array
Array
(
[0] => Array
(
[time_frame] => 2017-05-19
[email_data] => 0
)
[1] => Array
(
[time_frame] => 2017-05-20
[email_data] => 0
)
[2] => Array
(
[time_frame] => 2017-05-21
[email_data] => 0
)
[3] => Array
(
[time_frame] => 2017-05-22
[email_data] => 0
)
[4] => Array
(
[time_frame] => 2017-05-23
[email_data] => 0
)
[5] => Array
(
[time_frame] => 2017-05-24
[email_data] => 0
)
[6] => Array
(
[time_frame] => 2017-05-25
[email_data] => 0
)
second array
Array
(
[0] => Array
(
[time_frame] => 2017-05-20
[email_data] => 1
)
[1] => Array
(
[time_frame] => 2017-05-21
[email_data] => 2
)
[2] => Array
(
[time_frame] => 2017-05-24
[email_data] => 8
)
)
Now what I want to achieve is the data below:
[
{
"time_frame": "2017-05-19",
"email_data": "0"
},
{
"time_frame": "2017-05-20",
"email_data": "1"
},
{
"time_frame": "2017-05-21",
"email_data": "2"
},
{
"time_frame": "2017-05-22",
"email_data": "0"
},
{
"time_frame": "2017-05-23",
"email_data": "0"
},
{
"time_frame": "2017-05-24",
"email_data": "8"
},
{
"time_frame": "2017-05-25",
"email_data": "0"
}
]
Thanks in advance.

Answer 1

Check out this piece of code...
$data1 = array(
array('time_frame'=>'2017-05-19', 'email_data'=>0),
array('time_frame'=>'2017-05-20', 'email_data'=>0),
array('time_frame'=>'2017-05-21', 'email_data'=>0),
array('time_frame'=>'2017-05-22', 'email_data'=>0),
array('time_frame'=>'2017-05-23', 'email_data'=>0),
array('time_frame'=>'2017-05-24', 'email_data'=>0),
array('time_frame'=>'2017-05-25', 'email_data'=>0)
);
$data2 = array(
array('time_frame'=>'2017-05-20', 'email_data'=>1),
array('time_frame'=>'2017-05-21', 'email_data'=>2),
array('time_frame'=>'2017-05-24', 'email_data'=>8)
);
foreach ($data2 as $key2 => $value2)
{
foreach ($data1 as $key1 => $value1)
{
if($value2['time_frame'] == $value1['time_frame']) {
$data1[$key1] = $value2;
}
}
}
echo '<pre>';
print_r($data1);
echo '</pre>';

Answer 2

Why you do it using loop, php provide array_merge() function use it
example is here..
first array..
$first = array(
0 => Array
(
"time_frame" => "2017-05-20",
"email_data" => "1"
),
1 => Array
(
"time_frame" => "2017-05-21",
"email_data" => "2"
),
2 => Array
(
"time_frame" => "2017-05-24",
"email_data" => "8"
)
);
second array...
$second = array(
0 => Array
(
"time_frame" => "2017-05-19",
"email_data" => 0
),
1 => Array
(
"time_frame" => "2017-05-20",
"email_data" => 0
),
2 => Array
(
"time_frame" => "2017-05-21"
,"email_data" => 0
),
3 => Array
(
"time_frame" => "2017-05-22"
,"email_data" => 0
),
4 => Array
(
"time_frame" => "2017-05-23"
,"email_data" => 0
),
5 => Array
(
"time_frame" => "2017-05-24"
,"email_data" => 0
),
6 => Array
(
"time_frame" => "2017-05-25"
,"email_data" => 0
)
);
now your solutions is here..
$combined_array = array_merge($first,$second);
and it give you required result. Simple.
for printing result...
foreach($combined_array as $key){
print_r($key);
echo "<br> - - - - - - - - - - - - - - -- - - - - - - <br>";
}
