PHP favorite snippets

Enable logging

declare(strict_types=1);

ini_set('display_errors', '1');
ini_set('display_startup_errors', '1');
error_reporting(E_ALL);

Write string to file

$log = date('Y-m-d H:i:s') . ' Запись в лог';
file_put_contents(__DIR__ . '/log.txt', $log . PHP_EOL, FILE_APPEND);

Write array to file

// https://prowebmastering.ru/php-logging.html
$array = [
  'foo' => 'bar',
  'data' => [1, 2]
];

$log = date('Y-m-d H:i:s') . ' ' . print_r($array, true);
file_put_contents(__DIR__ . '/log.txt', $log . PHP_EOL, FILE_APPEND);

Результат работы PHP скрипта

ob_start();
// Вывод заголовков браузера.
foreach (get_headers('https://yandex.ru') as $name => $value) {
  echo "$name: $value\n";
}
$log = date('Y-m-d H:i:s') . PHP_EOL . ob_get_clean() . PHP_EOL;
file_put_contents(__DIR__ . '/log.txt', $log, FILE_APPEND);
// another example
$path = realpath(__DIR__);
$logPath = $path  . '/runtime/';

try {
  $command = "php $path/handler.php  > {$logPath}process.log 2>&1 &";
  exec($command);
} catch (Exception $exception) {
  echo $exception->getMessage();
}

Write PHP errors to logfile

ini_set('error_log', __DIR__ . '/php-errors.log');
error_log('Запись ошибки в лог', 0);

// More
$logPath = __DIR__ . '/runtime';
$errorMsg = date('Y/m/d H:i:s') . ': Сообщение в лог' . PHP_EOL;

error_log($errorMsg, 3, $logPath . '/errors.log');

// Simple logging function
function logger($message)
{
  $logPath = __DIR__ . '/runtime';
  if (!is_dir($logPath)) {
    mkdir($logPath, 0777, true);
  }

  $errorMsg = date('Y/m/d H:i:s') . ": $message" . PHP_EOL;
  error_log($errorMsg, 3, $logPath . '/errors.log');
}
// Вызываем логер
logger('Ошибка получения данных в файле ' . __FILE__);

Use Monolog

https://github.com/Seldaek/monolog

use Monolog\Logger;
use Monolog\Handler\StreamHandler;

$logPath = __DIR__ . '/runtime';
$logger = new Logger('warning');
$logger->pushHandler(new StreamHandler("$logPath/warning.log", Logger::WARNING));
$logger->warning('Ошибка!', ['name' => 'John']);
