log_message(string $level, string|stringable $message, array $context = []): void

• $level is a log level. Available levels: emergency, alert, critical, error, warning, notice, info, debug.

    • \Psr\Log\LogLevel::ERROR
    • \Psr\Log\LogLevel::WARNING

    • \Psr\Log\LogLevel::INFO
    • \Psr\Log\LogLevel::DEBUG.
• $message is a log message
• $context is a log context

Also, you can use already level-specific functions:

• log_emergency(string|Stringable $message, array $context = []): void
• log_alert(string|Stringable $message, array $context = []): void
• log_critical(string|Stringable $message, array $context = []): void
• log_error(string|Stringable $message, array $context = []): void
• log_warning(string|Stringable $message, array $context = []): void
• log_notice(string|Stringable $message, array $context = []): void
• log_info(string|Stringable $message, array $context = []): void
• log_debug(string|Stringable $message, array $context = []): void

log_message('info', 'Some info message');
log_message('error', 'Could not authenticate user with ID {user_id}', ['user_id' => $userId]);

log_info('Info message');
log_error('Error message');
log_warning('Warning message');
log_notice('Notice message');
log_debug('Debug message');
log_critical('Critical message');
log_alert('Alert message');
log_emergency('Emergency message');

• $key is a cache key
• $value is a cache value
• $ttl is a cache TTL

cache('key', 'value'); // returns "value" and sets cache with key "key" if it does not exist

cache('key', 'value', 3600); // sets cache with key "key" and value "value" for 1 hour
cache('key', 'value', new DateInterval('PT1H')); // also TTL can be an instance of DateInterval

cache('key', fn () => 'value'); // $value can be a closure. It will be executed only if cache with key "key" does not exist

cache(new StringableClass('key'), fn () => 'value'); // $key can be an instance of Stringable
cache(12345, fn () => 'value'); // $key can be an integer
cache(['key' => 'value', '!@#$%^&*()_+`' => '_)(*&^%$#@!~`'], fn () => 'value'); // $key can be an array. It will be serialized to a JSON and the following characters will be replaced to "_": {}()/\@:
