Управление выводом ошибок PHP

PHP предлагает гибкие настройки вывода ошибок, среди которых функия error_reporting($level) – задает, какие ошибки PHP попадут в отчет, могут быть значения:

• E_ALL – все ошибки,
• E_ERROR – критические ошибки,
• E_WARNING – предупреждения,
• E_PARSE – ошибки синтаксиса,
• E_NOTICE – замечания,
• E_CORE_ERROR – ошибки обработчика,
• E_CORE_WARNING – предупреждения обработчика,
• E_COMPILE_ERROR – ошибки компилятора,
• E_COMPILE_WARNING – предупреждения компилятора,
• E_USER_ERROR – ошибки пользователей,
• E_USER_WARNING – предупреждения пользователей,
• E_USER_NOTICE – уведомления пользователей.

Вывод ошибок в браузере

error_reporting(E_ALL); ini_set('display_errors', 'On'); 

В htaccess

php_value error_reporting "E_ALL" php_flag display_errors On

На рабочем проекте вывод ошибок лучше сделать только у авторизированного пользователя или в крайнем случаи по IP.

Запись ошибок в лог файл

error_reporting(E_ALL); ini_set('display_errors', 'Off'); ini_set('log_errors', 'On'); ini_set('error_log', $_SERVER['DOCUMENT_ROOT'] . '/logs/php-errors.log');

Файлы логов также не должны быть доступны из браузера, храните их в закрытой директории с файлом .htaccess:

Order Allow,Deny Deny from all

Или запретить доступ к файлам по расширению .log (заодно и другие системные файлы и исходники):

 Order Allow,Deny Deny from all 

Отправка ошибок на e-mail

Ошибки можно отправлять на е-mail разработчика, но приведенные методы не работает при критических ошибках.

Первый – register_shutdown_function() регистрирует функцию, которая выполнится при завершении работы скрипта, error_get_last() получает последнюю ошибку.

register_shutdown_function('error_alert'); function error_alert() < $error = error_get_last(); if (!empty($error)) < mail('mail@example.com', 'Ошибка на сайте example.com', print_r($error, true)); >>

Стоит учесть что оператор управления ошибками (знак @) работать в данном случаи не будет и письмо будет отправляться при каждой ошибке.

Второй метод использует «пользовательский обработчик ошибок», поэтому в браузер ошибки выводится не будут.

function error_alert($type, $message, $file, $line, $vars) < $error = array( 'type' =>$type, 'message' => $message, 'file' => $file, 'line' => $line ); error_log(print_r($error, true), 1, 'mail@example.com', 'From: mail@example.com'); > set_error_handler('error_alert');

Пользовательские ошибки

PHP позволяет разработчику самому объявлять ошибки, которые выведутся в браузере или в логе. Для создания ошибки используется функция trigger_error() :

trigger_error('Пользовательская ошибка', E_USER_ERROR);

Результат:

Fatal error: Пользовательская ошибка in /public_html/script.php on line 2

• E_USER_ERROR – критическая ошибка,
• E_USER_WARNING – не критическая,
• E_USER_NOTICE – сообщения которые не являются ошибками,
• E_USER_DEPRECATED – сообщения о устаревшем коде.

mail

Each line should be separated with a CRLF (\r\n). Lines should not be larger than 70 characters.

(Windows only) When PHP is talking to a SMTP server directly, if a full stop is found on the start of a line, it is removed. To counter-act this, replace these occurrences with a double dot.

String or array to be inserted at the end of the email header.

This is typically used to add extra headers (From, Cc, and Bcc). Multiple extra headers should be separated with a CRLF (\r\n). If outside data are used to compose this header, the data should be sanitized so that no unwanted headers could be injected.

If an array is passed, its keys are the header names and its values are the respective header values.

Note:

Before PHP 5.4.42 and 5.5.27, repectively, additional_headers did not have mail header injection protection. Therefore, users must make sure specified headers are safe and contains headers only. i.e. Never start mail body by putting multiple newlines.

Note:

When sending mail, the mail must contain a From header. This can be set with the additional_headers parameter, or a default can be set in php.ini .

Failing to do this will result in an error message similar to Warning: mail(): «sendmail_from» not set in php.ini or custom «From:» header missing . The From header sets also Return-Path when sending directly via SMTP (Windows only).

Note:

If messages are not received, try using a LF (\n) only. Some Unix mail transfer agents (most notably » qmail) replace LF by CRLF automatically (which leads to doubling CR if CRLF is used). This should be a last resort, as it does not comply with » RFC 2822.

The additional_params parameter can be used to pass additional flags as command line options to the program configured to be used when sending mail, as defined by the sendmail_path configuration setting. For example, this can be used to set the envelope sender address when using sendmail with the -f sendmail option.

This parameter is escaped by escapeshellcmd() internally to prevent command execution. escapeshellcmd() prevents command execution, but allows to add additional parameters. For security reasons, it is recommended for the user to sanitize this parameter to avoid adding unwanted parameters to the shell command.

Since escapeshellcmd() is applied automatically, some characters that are allowed as email addresses by internet RFCs cannot be used. mail() can not allow such characters, so in programs where the use of such characters is required, alternative means of sending emails (such as using a framework or a library) is recommended.

The user that the webserver runs as should be added as a trusted user to the sendmail configuration to prevent a ‘X-Warning’ header from being added to the message when the envelope sender (-f) is set using this method. For sendmail users, this file is /etc/mail/trusted-users .

Return Values

Returns true if the mail was successfully accepted for delivery, false otherwise.

It is important to note that just because the mail was accepted for delivery, it does NOT mean the mail will actually reach the intended destination.

Changelog

Version	Description
7.2.0	The additional_headers parameter now also accepts an array .

Examples

Example #1 Sending mail.

Using mail() to send a simple email:

// The message
$message = «Line 1\r\nLine 2\r\nLine 3» ;

// In case any of our lines are larger than 70 characters, we should use wordwrap()
$message = wordwrap ( $message , 70 , «\r\n» );

// Send
mail ( ‘caffeinated@example.com’ , ‘My Subject’ , $message );
?>

Example #2 Sending mail with extra headers.

The addition of basic headers, telling the MUA the From and Reply-To addresses:

$to = ‘nobody@example.com’ ;
$subject = ‘the subject’ ;
$message = ‘hello’ ;
$headers = ‘From: webmaster@example.com’ . «\r\n» .
‘Reply-To: webmaster@example.com’ . «\r\n» .
‘X-Mailer: PHP/’ . phpversion ();

mail ( $to , $subject , $message , $headers );
?>

Example #3 Sending mail with extra headers as array

This example sends the same mail as the example immediately above, but passes the additional headers as array (available as of PHP 7.2.0).

$to = ‘nobody@example.com’ ;
$subject = ‘the subject’ ;
$message = ‘hello’ ;
$headers = array(
‘From’ => ‘webmaster@example.com’ ,
‘Reply-To’ => ‘webmaster@example.com’ ,
‘X-Mailer’ => ‘PHP/’ . phpversion ()
);

mail ( $to , $subject , $message , $headers );
?>

Example #4 Sending mail with an additional command line parameter.

The additional_params parameter can be used to pass an additional parameter to the program configured to use when sending mail using the sendmail_path .

Example #5 Sending HTML email

It is also possible to send HTML email with mail() .

// Multiple recipients
$to = ‘johny@example.com, sally@example.com’ ; // note the comma

// Subject
$subject = ‘Birthday Reminders for August’ ;

// Message
$message = ‘

Here are the birthdays upcoming in August!

Person	Day	Month	Year
Johny	10th	August	1970
Sally	17th	August	1973

‘ ;

// To send HTML mail, the Content-type header must be set
$headers [] = ‘MIME-Version: 1.0’ ;
$headers [] = ‘Content-type: text/html; charset=iso-8859-1’ ;

// Additional headers
$headers [] = ‘To: Mary , Kelly ‘ ;
$headers [] = ‘From: Birthday Reminder ‘ ;
$headers [] = ‘Cc: birthdayarchive@example.com’ ;
$headers [] = ‘Bcc: birthdaycheck@example.com’ ;

// Mail it
mail ( $to , $subject , $message , implode ( «\r\n» , $headers ));
?>

Note:

If intending to send HTML or otherwise Complex mails, it is recommended to use the PEAR package » PEAR::Mail_Mime.

Notes

Note:

The SMTP implementation (Windows only) of mail() differs in many ways from the sendmail implementation. First, it doesn’t use a local binary for composing messages but only operates on direct sockets which means a MTA is needed listening on a network socket (which can either on the localhost or a remote machine).

Second, the custom headers like From: , Cc: , Bcc: and Date: are not interpreted by the MTA in the first place, but are parsed by PHP.

As such, the to parameter should not be an address in the form of «Something «. The mail command may not parse this properly while talking with the MTA.

Note:

It is worth noting that the mail() function is not suitable for larger volumes of email in a loop. This function opens and closes an SMTP socket for each email, which is not very efficient.

For the sending of large amounts of email, see the » PEAR::Mail, and » PEAR::Mail_Queue packages.

How to get error info on sending email with PHPMailer in PHP

How to get error info on sending email with PHPMailer in PHP

I am using PHPMailer to send emails with the SMTP server in PHP. But, the emails are not sending and the error message is not showing. I want to get the error info from PHPMailer to know about the issue with sending emails.

Suggest the best method for error handling with PHPMailer.

Asked: Jan 22,2022 In: PHP

Use try & catch block to handle errors with PHPMailer in PHP.

use PHPMailer\PHPMailer\PHPMailer; use PHPMailer\PHPMailer\SMTP; use PHPMailer\PHPMailer\Exception; $mail = new PHPMailer(true); try < //Server settings $mail->SMTPDebug = SMTP::DEBUG_SERVER; $mail->isSMTP(); $mail->Host = 'smtp.example.com'; $mail->SMTPAuth = true; $mail->Username = 'user@example.com'; $mail->Password = 'secret'; $mail->SMTPSecure = PHPMailer::ENCRYPTION_SMTPS; $mail->Port = 465; //Recipients $mail->setFrom('from@example.com', 'Mailer'); $mail->addAddress('joe@example.net', 'Joe User'); //Content $mail->isHTML(true); $mail->Subject = 'Email subject'; $mail->Body = 'Your email message'; $mail->send(); echo 'Message has been sent'; > catch (Exception $e) < echo "Message could not be sent. Mailer Error: ErrorInfo>"; >

You can also use the $mail->ErrorInfo method to display error info from the PHPMailer library.

if(!$mail->send()) < echo 'Message could not be sent.'; echo 'Mailer Error: ' . $mail->ErrorInfo; > else
