I have 4 tables they already have foreign key.
aluno:
id
matricula
username
curso_id // referencia a id_cursos da tabela cursos, coluna
id_cursos.
cursos:
id_cursos
nome_cursos
modulos:
id_modulos
nome_modulos
cursos_id //faz referencia a tabela cursos, coluna id_cursos.
materias:
id_materias
nome_materias
modulos_id // faz referencia a tabela modulos, coluna id_modulos.
I need to return the columns of 1 user:
<?php
function get_user_data(){
$user = $_SESSION["Login"];
$pass = $_SESSION["Password"];
$pdo = cnx();
$select = $pdo->query("select * from aluno where matricula = '$user' and password ='$pass' ");
$select->execute();
$rowCount = $select->rowCount();
if ($rowCount == 0):
header("Location:index.php?out=1");
else:
return $select;
endif;
}
function stats_session(){
session_start();
if (isset($_SESSION['Login']) and isset($_SESSION['Password'])) {
$data = get_user_data();
$data->execute();
foreach ($data as $key) {
$curso_id = $key['id_curso'];
$pdo = cnx();
$select = $pdo->query("SELECT C.*, A.*, MO.*, MA.* FROM aluno A JOIN cursos C on C.id_cursos = '$curso_id' JOIN modulos MO on MO.id_modulos = '$curso_id' JOIN materias MA on MA.id_materias = MO.id_modulos");
$select->execute();
return $select;
}
} else {
header('Location:index.php');
}
}
$query = stats_session();
$query->execute();
foreach ($query as $key) {
var_dump(json_encode($key));
}
?>
is returning this:
C:\wamp64\www\frequencia.php:6:string '{"id_cursos":"1","0":"1","nome_curso":"Assistente Administrativo","1":"Assistente Administrativo","id":"1","2":"1","matricula":"1234","3":"1234","password":"1234","4":"1234","username":"2626","5":"2626","id_curso":"1","6":"1","id_modulos":"1","7":"1","nome_modulos":"modulo basico","8":"modulo basico","cursos_id":"1","9":"1","id_materias":"1","10":"1","nome_materias":"Introdu\u00e7\u00e3o a adm","11":"Introdu\u00e7\u00e3o a adm","modulos_id":"1","12":"1"}' (length=458)

Only the first one is correct, it is returning the data of the 2 users that I have in the student table, how do I return only what is in the variable $ course_id of the table column column course_id?
