PHP - Push data to array in foreach loop [duplicate] - php

Question

This question already has answers here:
PHP Append an array to a sub array
(2 answers)
Closed 2 years ago.
I want to achieve below array format:
{
"success": true,
"results": [
{
"name" : "Choice 1",
"value" : "value1",
"text" : "Choice 1"
},
{
"name" : "Choice 2",
"value" : "value2",
"text" : "Choice 2"
}
]
}
However, I am using PHP and a foreach loop, to return some values from my database:
//Search for clients in our database.
$stmt = $dbh->prepare("SELECT * FROM customers");
$stmt->execute();
$showAll = $stmt->fetchAll();
I then have my first part of the array, and my foreach loop:
$data = array(
"success" => false,
"results" => array()
);
foreach ($showAll as $client) {
$data_array[] =
array(
'name' => $client['name'],
'value' => $client['name'],
'text' => $client['name']
);
}
Above only outputs:
[
{
"name":"Choice 1",
"value":"value 1",
"text":"Choice 1"
},
{
"name":"Choice 2",
"value":"value2",
"text":"Choice 2"
}
]
So it is missing the top part of my original array - but I want to loop through each database results in "results": [ ... ]

Answer 1

Try this
$data = array(
"success" => false,
"results" => array()
);
foreach ($showAll as $client) {
$data['results'][] = array(
'name' => $client['name'],
'value' => $client['name'],
'text' => $client['name']
);
}
$data['success'] = true; // if you want to update `status` as well
echo json_encode($data);

Answer 2

After creating $data_array array just add few lines which i have in my post.
Try this code snippet here(with sample input)
ini_set('display_errors', 1);
foreach ($showAll as $client)
{
$data_array[] = array(
'name' => $client['name'],
'value' => $client['name'],
'text' => $client['name']
);
}
// add these lines to your code.
$result=array();
$result["success"]=true;
$result["results"]=$data_array;
echo json_encode($result);

Answer 3

try this as you have an array inside the $data_array on Key "Results" so you should use "results" as a key also and then try to push data in that array
foreach ($showAll as $client) {
$data_array["results"][] =
array(
'name' => $client['name'],
'value' => $client['name'],
'text' => $client['name']
);
}

You can simply use json_encode and push it to your result array
$data = array(
"success" => false,
"results" => array()
);
$result = [
[
"name" => "Choice 1",
"value" => "value 1",
"text" => "Choice 1"
],
[
"name" => "Choice 2",
"value" => "value2",
"text" => "Choice 2"
]
];
$data['results'] = json_encode($result);
