PHP has a build function called array_column ()
Using this function a new array be created with the values of a certain key in a multi-dimension array.
The function has 5 parameters & 2 are mandatory to use.
- input : Take value from the multidimensional array.
- column_key : The value of the key for the index.
- index_key : If you want to give a key to the index as a new array key. It is not mandatory to use it.
Example
<?php
$records = array(
array(
'id' => 2135,
'first_name' => 'John',
'last_name' => 'Doe',
),
array(
'id' => 3245,
'first_name' => 'Sally',
'last_name' => 'Smith',
),
array(
'id' => 5342,
'first_name' => 'Jane',
'last_name' => 'Jones',
),
array(
'id' => 5623,
'first_name' => 'Peter',
'last_name' => 'Doe',
)
);
$first_names = array_column($records, 'first_name');
print_r($first_names);
?>
Result
Array (
[0] => John
[1] => Sally
[2] => Jane
[3] => Peter
)
Another example Using the index key,
Example
<?php
$records = array(
array(
'id' => 2135,
'first_name' => 'John',
'last_name' => 'Doe',
),
array(
'id' => 3245,
'first_name' => 'Sally',
'last_name' => 'Smith',
),
array(
'id' => 5342,
'first_name' => 'Jane',
'last_name' => 'Jones',
),
array(
'id' => 5623,
'first_name' => 'Peter',
'last_name' => 'Doe',
)
);
$last_names = array_column($records, 'last_name', 'id');
print_r($last_names);
?>
Result
Array (
[2135] => Doe
[3245] => Smith
[5342] => Jones
[5623] => Doe
)
