how to combine 2 querys in the same vector (json_encode and php)

Matrix :

I believe it's a simple question I want to run both queries but I don't know how

hello people, I believe this is a simple matter I want execute the two queries

SELECT * FROM diligencias WHERE idprocesso = '$process_id' and SELECT * FROM processos WHERE id = '$process_id'

code working only with one query:

<?php
include("../../includes/conectar.php");

if(isset($_POST['id']) && isset($_POST['id']) != "")
{
    $process_id = $_POST['id'];
    $qryLista = mysqli_query($con, "SELECT * FROM processos WHERE id = '$process_id'");

    while($resultado = mysqli_fetch_assoc($qryLista)){
        $vetor[] = array_map('utf8_encode', $resultado); 
    }    

    echo json_encode($vetor);
}
?>

Nick :

If the tables don't have the same column names, you can simply JOIN them using this query:

SELECT *
FROM processos p
JOIN diligencias d ON d.idprocesso = p.id
WHERE p.d = '$process_id'

If the tables do have similar column names, you will need to provide column aliases for the overlapping names e.g.

SELECT p.*, d.id AS diligencias_id, d.xxx AS diligencias_xxx
FROM processos p
JOIN diligencias d ON d.idprocesso = p.id
WHERE p.d = '$process_id'

Note that in your existing code

isset($_POST['id']) != ""

should be

$_POST['id'] != ""

Also you are vulnerable to SQL injection, and should use a prepared query. For example:

$process_id = $_POST['id'];
$stmt = $con->prepare("SELECT *
    FROM processos p
    JOIN diligencias d ON d.idprocesso = p.id
    WHERE p.d = ?");
$stmt->bind_param('i', $process_id);
$qryLista = $stmt->get_result();
while($resultado = $qryLista->fetch_assoc()){
    $vetor[] = array_map('utf8_encode', $resultado); 
}
echo json_encode($vetor);
