How to create an array with Object from an SQL query

Question

I need the following result within a variable from a query PHP + Mysql:

array(1) {
    [0] => object(stdClass) #1 (3) { 
    ["id"]= > string(2) "1" 
    ["nome"] => string(5) "teste" 
    ["email"] => string(18) "[email protected]"
    }
}

The above result is obtained like this:

$results = array((object) array( 
      'id' => '1', 
      'nome' => 'teste', 
      'email' => '[email protected]'
    ));

UPDATE: If I have 1 or more ID’s, that is, 1 or more names and emails

array(2) {
  [0]=>
  object(stdClass)#2195 (3) {
    ["id"]=>
    string(2) "1"
    ["nome"]=>
    string(16) "testao"
    ["email"]=>
    string(14) "[email protected]"
  }
  [1]=>
  object(stdClass)#2196 (3) {
    ["id"]=>
    string(2) "2"
    ["nome"]=>
    string(17) "testado"
    ["sml_email"]=>
    string(18) "[email protected]"
  }
}

To connect to Mysql database:

<?php
$servername = "localhost";
$username = "username";
$password = "password";

// Create connection
$conn = new mysqli($servername, $username, $password);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 
echo "Connected successfully";
?>

Select in the database:

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 

$sql = "SELECT id, firstname, lastname FROM MyGuests";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // output data of each row
    while($row = $result->fetch_assoc()) {
        echo "id: " . $row["id"]. " - Name: " . $row["firstname"]. " " . $row["lastname"]. "<br>";
    }
} else {
    echo "0 results";
}
$conn->close();
?>

In your case you can take the returned values and play straight:

$results = array((object) array( 
      'id' => $row["id"], 
      'nome' => $row["nome"], 
      'email' => $row["email"]
    ));

Without having your data to use example becomes difficult. But I believe that with this code you can connect to the database, select and mount the array.

UPDATING

To do in the loop with the bank select is like this:

$newArray = array();
if ($result->num_rows > 0) {
    // output data of each row
    while($row = $result->fetch_assoc()) {
        
	
	$newArray[] = array(


	'id' => $row["id"], 
        'nome' => $row["nome"], 
        'email' => $row["email"]


           );

    }
}

In the above code you put an array inside another, maybe this is confusing you.

Look at that one Fiddler and see if it gets easier, in it I stick an object inside the array. I believe it will be better in your case, but again, without your code to pick up and change it’s hard to understand what you really need.

To print as you said, use the function below:

public function listar(){   //new Pessoa(id, nome, telefone, endereco)
$query = "SELECT *FROM pessoa ";            
try {               
    $stmt = $this->conexao->mysqli->prepare($query);
    if($stmt->execute()){
        $result = $stmt->get_result();
        while ($row = $result->fetch_object()) {
            array[] = $row;
        }
        $stmt->free_result();
        $stmt->close();
        return $this->array;
    }else{
        echo "Erro ao buscar dados";
    }
} 
catch (Exception $e) {
  echo $e->errorMessage();
}

}

To call the function, do:

$exemplo = new daoPessoa();
$pessoa = $exemplo->listar();

<!-- para imprimir organizado faça: -->
<pre>
<?php print_r(pessoa); ?>
<pre>

Answer 3

Simply assign this return to a new variable, doing the following:

Return as an object:

<?php

$con = new mysqli('localhost', 'root', '', 'exemplo');

if($query = $con->query('SELECT * FROM exemplo LIMIT 5')){
    while($resultado = $query->fetch_object()){
        $obj[] = $resultado;
    }
}

print_r($obj);

?>

Return as converted association to output

<?php

$con = new mysqli('localhost', 'root', '', 'exemplo');

if($query = $con->query('SELECT * FROM exemplo LIMIT 5')){
    while($resultado = $query->fetch_assoc()){
        $obj[] = (object) $resultado;
    }
}

print_r($obj);

?>

To return the results just walk them like any other object, but within a loop:

foreach($obj as $key=>$val){
    # imprime o indice da array 
    # e o respectivos valores de cada objecto nessa array
    print "#{$key} " . $obj[$key]->titulo . "<br/>";
}
