Hello Stackoverflow community!
I have a problem i have this script (below) and when i access the file with right switch cases i become a white screen. the first script doesnt work the seconds works fine. i isolated the error in my opinion: the sql statement (table and columns exist)
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "regressiontest";
try {
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
switch($operation){
case "managerList": {
$stmt = $conn->query("
SELECT
*
FROM
regressiontest.campaign_run;");
} break;
}
$stmt->execute();
$result = $stmt->setFetchMode(PDO::FETCH_ASSOC);
$output = $stmt->fetchAll();
switch($compute){
case "json": {
echo json_encode($output, JSON_NUMERIC_CHECK);
}
}
}
catch(PDOException $e) {
echo "Error: " . $e->getMessage();
}
$conn = null;
?>
And this cases works fine
<?php
//check for error output
if(isset($_GET['error'])){
if($_GET['error'] == "false"){
error_reporting(0);
} else if($_GET['error'] == "true"){
ini_set('error_reporting', E_ALL);
} else {
error_reporting(0);
}
} else {
error_reporting(0);
}
//check for timelimit
if(isset($_GET['timelimit'])){ set_time_limit($_GET['timelimit']); } else { set_time_limit(0); }
//check for operation
if(isset($_GET['operation'])){ $operation = $_GET['operation']; } else { exit; }
//check for compute
if(isset($_GET['compute'])){ $compute = $_GET['compute']; } else { exit; }
$servername = "localhost";
$username = "root";

} break;
