Error Handling

Try-Catch Exception

<?php
try {
    $file = fopen("tidak_ada.txt", "r");
    if (!$file) {
        throw new Exception("File tidak ditemukan");
    }
} catch (Exception $e) {
    echo "Error: " . $e->getMessage();
} finally {
    echo "Selesai";
}
?>

Custom Exception

<?php
class InvalidAgeException extends Exception {
    public function __construct($message = "", $code = 0) {
        parent::__construct($message, $code);
    }
}

try {
    $age = 15;
    if ($age < 18) {
        throw new InvalidAgeException("Usia tidak valid");
    }
} catch (InvalidAgeException $e) {
    echo "Custom Error: " . $e->getMessage();
}
?>

Error Reporting

<?php
// Set error reporting level
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Log errors to file
ini_set('log_errors', 1);
ini_set('error_log', '/path/to/error.log');

// Custom error handler
function myErrorHandler($errno, $errstr) {
    echo "Error: " . $errstr;
}

set_error_handler("myErrorHandler");
?>

Multiple Catch Blocks

<?php
try {
    // Code yang mungkin error
} catch (TypeError $e) {
    echo "Type Error: " . $e->getMessage();
} catch (DivisionByZeroError $e) {
    echo "Division Error: " . $e->getMessage();
} catch (Exception $e) {
    echo "General Error: " . $e->getMessage();
}
?>
