I am using PDO statement like below
$sql1 = "select food_typename from foodtypes WHERE 1";
$statement1 = $pdo->prepare($sql1);
$statement1->execute();
$results1 = $statement1->fetchAll(PDO::FETCH_ASSOC);
print_r($results1);
I am getting output as below:
Array
(
[0] => Array
(
[food_typename] => Punjabi
)
[1] => Array
(
[food_typename] => Indian
)
)
I want it be like
Array('Punjabi','Indian')
Any suggestions please?
If you're running PHP >= 5.5
$results = array_column($results1, 'food_typename');
If you're running earlier versions of PHP,
$results = array_map(
$results1,
function($value) {
return $value['food_typename'];
}
);
Though I don't really understand why you can't work with the original array in the first place
You can use array_map but foreach works just as well and actually runs faster than array_map for cases like this:
// Set a test array.
$results1 = array();
$results1[] = array('food_typename' => 'Punjabi');
$results1[] = array('food_typename' => 'Indian');
// Set the final reults in an array.
$results_final = array();
foreach ($results1 as $results1_value) {
$results_final[] = $results1_value['food_typename'];
}
// Dump the line array for debugging.
echo '<pre>';
print_r($results_final);
echo '</pre>';
And the output of that would be:
Array
(
[0] => Punjabi
[1] => Indian
)
The query way:
SELECT GROUP_CONCAT(food_typename), 1 AS dummy
FROM foodtypes
GROUP BY dummy
Then you need to retrieve the first field of the only record you will get back from mysql, and turn it into an array: see return group_concat data as array
