You can use the watchdogfunction:

您可以使用该watchdog功能：

watchdog($type, $message, $variables = array(), $severity = WATCHDOG_NOTICE, $link = NULL)

Quoting the manual, the parameters are :

引用手册，参数是：

• $typeThe category to which this message belongs.
• $messageThe message to store in the log.
• $variablesArray of variables to replace in the message on display or NULL if message is already translated or not possible to translate.
• $severityThe severity of the message, as per RFC 3164
• $linkA link to associate with the message.

• $type此消息所属的类别。
• $message要存储在日志中的消息。
• $variables要在显示的消息中替换的变量数组，如果消息已翻译或无法翻译，则为 NULL。
• $severity消息的严重性，根据 RFC 3164
• $link与消息关联的链接。

And the error levels can be found on the page of watchdog_severity_levels. For an error, you'll most probably use WATCHDOG_ERROR, or maybe even something more "critical", depending on the kind of error.

错误级别可以在 的页面上找到watchdog_severity_levels。对于错误，您很可能会使用WATCHDOG_ERROR，甚至可能使用更“关键”的东西，具体取决于错误的类型。

Drupal 8

// Logs a notice
\Drupal::logger('my_module')->notice($message);
// Logs an error
\Drupal::logger('my_module')->error($message);

1) Indeed, watchdog is a standard way to record own PHP errors.

1）确实，看门狗是记录自己的PHP错误的标准方式。

2) Alternatively, if you need to immediately see error messages while debugging your Drupal pages, you may want to see them logged/printed right at the related page - in FireBug console. Sometimes is this very convenient when you can see page-related just-in-time logs. This requires - Develmodule, Firebugextension to FireFox and possibly Firephp.

2) 或者，如果您需要在调试 Drupal 页面时立即查看错误消息，您可能希望在相关页面上查看它们的记录/打印 - 在 FireBug 控制台中。有时，当您可以查看与页面相关的即时日志时，这会非常方便。这就要求-杰韦利模块，Firebug的扩展，Firefox和可能Firephp。

You can use the dfb() function to write log messages directly to the general Firebug console.

您可以使用 dfb() 函数将日志消息直接写入通用 Firebug 控制台。

dfb($input, $label = NULL)

If you want to keep your Drupal-related log messages out of the normal Firebug console, you can write messages to the Drupal for Firebuglog with the firep() function:

如果您想将与 Drupal 相关的日志消息保留在普通 Firebug 控制台之外，您可以使用 firep() 函数将消息写入Drupal for Firebug日志：

firep($item, $optional_title)

Watchdog is the way to go for a production system no doubt but during debugging I find the drupal_set_messagefunction useful.

毫无疑问，看门狗是生产系统的必经之路，但在调试过程中，我发现该drupal_set_message功能很有用。

It outputs the message to the screen where the 'Operation Successful'-type messages are normally displayed (so make sure you remove them before making the site Live).

它将消息输出到通常显示“操作成功”类型消息的屏幕（因此请确保在使站点上线之前将其删除）。

In drupal 7 we can log message by following method:

在 drupal 7 中，我们可以通过以下方法记录消息：

drupal watchdog function we can use to log message in database , make sure we have enabled optional core module for Database Logging at /admin/build/modules.

我们可以使用 drupal 看门狗功能在数据库中记录消息，确保我们在 /admin/build/modules 中启用了可选的数据库日志记录核心模块。

watchdog($type, $message, $variables = array(), $severity = WATCHDOG_NOTICE, $link = NULL)

$type:The category to which this message belongs , Example: PHP,cron.., we can filter message by type.

$type：此消息所属的类别，例如：PHP,cron..，我们可以按类型过滤消息。

$message :The message to store in the log,Example: 'The following module is missing from the file system: security_review'

$message :要存储在日志中的消息，例如：'文件系统中缺少以下模块：security_review'

$variables :Array of variables to replace in the message on display or NULL if message is already translated or not possible to translate. to make message translated , do not pass dynamic value pass variables in the message should be added by using placeholder strings.

$variables ：要在显示的消息中替换的变量数组，如果消息已经翻译或无法翻译，则为 NULL。要使消息翻译，不要在消息中传递动态值传递变量，应使用占位符字符串添加。

Example:watchdog('cg_volunteer', 'cg in form_alter %formly', array('%formly' => $form['#id']), WATCHDOG_NOTICE, $link = NULL);

示例：watchdog('cg_volunteer', 'cg in form_alter %formly', array('%formly' => $form['#id']), WATCHDOG_NOTICE, $link = NULL);

$severityThe severity of the message,logs can be filter by severity as per RFC 3164. Possible values are WATCHDOG_ERROR, WATCHDOG_WARNING, etc. For more example see https://api.drupal.org/api/drupal/includes!bootstrap.inc/function/watchdog/7.x

$severity消息的严重性，日志可以根据 RFC 3164 的严重性进行过滤。可能的值为 WATCHDOG_ERROR、WATCHDOG_WARNING 等。更多示例请参见https://api.drupal.org/api/drupal/includes!bootstrap。 inc/function/watchdog/7.x

$link: A link to associate with the message.

$link：与消息关联的链接。

Example

例子

// for logs notices

// 用于日志通知

watchdog('my_module', $message, array());

// for Loging Error

// 用于记录错误

watchdog('my_module', $message, array(), WATCHDOG_ERROR);

In drupal 8 we used following method:

在 drupal 8 中，我们使用了以下方法：

// For Logs a notice.

// 对于日志通知。

\Drupal::logger('my_module')->notice($message);

// For Logs an error.

// 对于日志错误。

\Drupal::logger('my_module')->error($message);

// For Alert, action must be taken immediately.

// 对于警报，必须立即采取行动。

\Drupal::logger('my_module')->alert($message);

// For Critical message.

// 对于关键消息。

\Drupal::logger('my_module')->critical($message);

// For Debug-level messages.

// 对于调试级别的消息。

\Drupal::logger('my_module')->debug($message);

//For Emergency, system is unusable.

//对于紧急情况，系统不可用。

\Drupal::logger('my_module')->emergency($message);

//For Warning

//用于警告

\Drupal::logger('my_module')->warning($message);

//For Informational messages.

//对于信息性消息。

\Drupal::logger('my_module')->info($message);

Also for translate we should not use t() function.

同样对于翻译，我们不应该使用 t() 函数。

\Drupal::logger('my_module')->alert('Message from @module: @message.', [
'@module' => $module,
'@message' => $message,
]);

this will be translated on run time.

这将在运行时进行翻译。

Example :

例子 ：

\Drupal::logger('content_entity_example')->notice('@type: deleted %title.',
array(
'@type' => $this->entity->bundle(),
'%title' => $this->entity->label(),
));

Both watchdogfor D7 & \Drupal::loggerfor D8 will write log in watchdogtable (in your database), and with HUGE data logged, you can imagine performance impact.

无论watchdog对于D7及\Drupal::logger为D8会写日志watchdog表（数据库），并与庞大的数据记录，你能想象的性能影响。

You can use error_logphp function to do it (see PHP manual).

您可以使用error_logphp 函数来做到这一点（请参阅PHP 手册）。

error_log("Your message", 3, "/path/to/your/log/file.log");

You need to have permission to write in your log file (/path/to/your/log/file.log)

您需要具有写入日志文件的权限 ( /path/to/your/log/file.log)
