How to retrieve all data from mysql database using php? - php

Question

I have a another php file that has the function to connect to the database (does so successfully) and also a function getEvent that contains the sql statement.
The code below successfully retrieves one data row from the database but i need it to return all data from the table.
<?php
// include db connect class
require_once 'include/DB_Functions.php';
// connecting to db
$db = new DB_Functions();
// array for JSON response
$response = array();
// get all events from events table
$event = $db->getEvent();
// check for empty result
if($event !=FALSE){
$response["error"]=FALSE;
$response["uuid"] = $event["eventID"];
$response["eventdetails"]["title"] = $event["title"];
echo json_encode($response);
}else{
$response["error"]=TRUE;
$response["error_msg"] = "No events to display";
echo json_encode($response);
}
?>
the getEvent method
public function getEvent(){
$stmt= $this->conn->prepare("SELECT * from eventdetails");
$stmt->execute();
$event= $stmt->store_result();
if ($stmt->execute()) {
$event = $stmt->get_result()->fetch_assoc();
$stmt->close();
return $event;
} else {
// events dont existed
$stmt->close();
return null;
}

If youwant to return an array containing all the results from a query then use the fetchAll() method of the PDOStatement Class
public function getEvent(){
$stmt = $this->conn->prepare("SELECT * from eventdetails");
$stmt->execute();
$events = $stmt->fetchAll();
return $events;
}
