Запись в лог-файл в PHP
Несколько вариантов как быстро организовать запись данных в лог-файл.
Строки текста
$log = date('Y-m-d H:i:s') . ' Запись в лог'; file_put_contents(__DIR__ . '/log.txt', $log . PHP_EOL, FILE_APPEND);Запись в лог-файле:

Если нужно записать в лог обычный массив, массив с индексами или многомерный массив, поможет функция print_r() .
$array = array( 'foo' => 'bar', 'helo' => 'world', 'array' => array(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);Запись в лог-файле:
2019-02-02 16:43:27 Array ( [foo] => bar [helo] => world [array] => Array ( [0] => 1 [1] => 2 ) )В одну строку
$array = array( 'foo' => 'bar', 'helo' => 'world', 'array' => array(1, 2) ); $log = date('Y-m-d H:i:s') . ' '; $log .= str_replace(array(' ', PHP_EOL), '', print_r($array, true)); file_put_contents(__DIR__ . '/log.txt', $log . PHP_EOL, FILE_APPEND);2019-02-02 16:56:00 Array([foo] => bar[helo] => world[array] => Array([0] => 1[1] => 2))Результат работы PHP скрипта
Если нужно добавить в лог результат работы PHP скрипта, помогут функции буферизации ob_start() и ob_get_clean() .
ob_start(); // Вывод заголовков браузера. foreach (getallheaders() 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);Запись в лог-файле:

Если логирование предполагает фиксацию только ошибок, то лучше писать их в общий лог PHP, подробнее на php.net.
error_reporting(E_ALL); ini_set('error_log', __DIR__ . '/php-errors.log'); error_log('Запись в лог', 0);[02-Feb-2019 20:18:17 Europe/Moscow] Запись в логPhp send errors to log file
