Php Send Mail Smtp Authentication – Today I want to share with you a guide on sending PHP emails, one of the most popular web development languages.
PHP’s built-in mail() function is very simple but at the same time, it provides limited functionality for sending emails. You won’t be able to add attachments to your emails, and it will also be difficult to create a beautiful HTML template with embedded images.
Php Send Mail Smtp Authentication
The downside of the PHP mail() function is that email is sent from your web server, which can lead to deliverability issues due to security concerns such as spam and blacklisting suspicions. The best way to overcome this problem is to send messages through an SMTP server, however, this functionality is also limited. PHP mail() usually doesn’t allow you to use an external SMTP server, and it doesn’t support SMTP authentication.
How To Set Up Your Smtp Server
In other words, I don’t recommend using PHP’s built-in mail() function and I recommend you avoid the headache of installing an external address package.
If you’re still committed to PHP’s built-in mail() function and are up for the challenge, let’s take a look at the source code and its key parameters.
The body of the message can be written in HTML. However, as I mentioned above, it should be easy. PHP mail() function, the HTML part will look like this:
Where do I specify SMTP settings? This is a fair question. Go to the PHP installation folder and configure them in the “php.ini” file. But this will only work for solutions like localhost or Xmapp because as I already mentioned, the PHP mail function does not support SMTP authentication and does not allow sending messages through external servers.
Send Email Using Php From Smtp Authentication With Phpmailer
There are some other options that are pretty dirty, but I won’t promote them and I don’t recommend using external PHP mail packages to send mail through an external SMTP server.
PHPMailer is a classic email sending library for PHP. It supports different ways to send email messages like email (), Send email, qmail and send directly to the SMTP server. In addition, it provides a list of complex features:
Until version 5, PHPMailer provided a “PHPMailerAutoload.php” file, so just include it in your script and create a PHPMailer instance.
Starting with the release of PHPMailer 6.0 in August 2017, you need to install it, preferably through Composer, the dependency manager for PHP (this way is recommended by the creators of PHPMailer on Github). After installing Composer, add this line to your composer.json file:

If you don’t want to install Composer, for example, while working in a test environment, you can download the files with the PHPMailer source code, then copy the contents of the PHPMailer folder to one of the Include_path directories specified in your configuration PHP and manually load each class file:
Adding an exception class will help you handle and debug errors. In PHP it works like any other programming language. So, otherwise, if there’s an error in your email sending code, you’ll see the exception class not found message, but you won’t be given any details on how to debug it. Debugging is a separate part of this post that I will describe.
To test PHP’s email functionality, I’ll use Mailtrap, a fake SMTP server, to bypass our inboxes, or worse, our customers’ inboxes. Once you are sure that everything is working properly and that your email messages look right, you can easily change the SMTP settings in our examples with your own server, whether you prefer a local service or a third party service party like Gmail. (Just a note, if you want to use the XOAUTH2 Gmail authentication class, you’ll also need to add a dependency to the league/oauth2-client package in your composer.json.)
If you’re not using MailTrap yet, create a free account, go to your inbox, and copy the following values into your PHPMailer script from the SMTP Settings tab:
How To Configure Smtp To Send Email On Siteground
You probably use HTML to design your email ads. So, let’s review some examples of using HTML methods and attributes.
With PHPMailer, you can even create a nice HTML email by sending emails with custom formatting, images and attachments. For your convenience, PHPMailer provides options to read HTML message bodies from external files, convert reference images to embedded ones, and convert HTML to other basic plain text bodies. That way, you won’t overload your messaging code with HTML and you can update your HTML template independently. To include a specific HTML file, add these attributes:
The “Message Sent” result tells you that your code executed correctly. To check delivery results and details, go to your MailTrap inbox: your messages will be there in seconds.
With Mailtrap, you’ll be able to review your HTML code, raw data, test email browsers and make sure your message isn’t marked as spam or your sending domain isn’t blacklisted.
Html From To Email Using Smtp In Php With Source Code
Once you’ve confirmed that your PHPMailer sending results match your expectations, you can switch to sending regular emails via any SMTP server of your choice.
If you’re having problems sending email through an SMTP server, the SMTPDebug command will help you find those errors and figure out what to fix.
For example, I entered an invalid hostname: mailtrap.io instead of smtp.mailtrap.io. And a message is immediately received that an error occurred at the first step of communication with the server.
This example shows where the error occurs: Now SMTP, its hostname and port are valid but the login and password combination is not found, so you recheck and modify your credentials.
Cannot Send Mail With Smtp
GitHub has several detailed articles about debugging and troubleshooting, refer to them when you need to dive deeper into these topics.
In this article, I have described the basic principles of PHP email sending, syntax and parameters. In addition, I reviewed the two main ways to send email with PHP: its built-in email function and PHPMailer, the most popular external email package.
The latter is arguably a more advanced solution with SMTP authentication support and a wider set of HTML-related features, however, if you’re sending plain-text notifications via localhost, the PHP mail function ( ) to be an option.
Beyond PHPMailer, there are some notable solutions for creating and sending HTML emails via SMTP servers, such as the PEAR Mail package, Swift Mailer, or the Zend Framework. It is a standout among the most famous open source PHP libraries. To send a message. In this article, we’ll discuss why you should use PHPMailer instead
Smtp Enabled But Emails Still Seem To Send Via Php?
Capabilities and we will demonstrate some code tests of commonly accepted methods of using this library. Most of the time, this is a counter-intuitive alternative to PHP’s email function, however, there are many different situations where the email capability is not customizable enough to achieve what you need.
More importantly, PHPMailer provides a deprecated interface, but is not suspicious of malware. PHP developers, for the most part, prefer not to create $headers strings when sending messages using the mail() function because they have to go too far – PHPMailer makes this a breeze. While PHPMailer makes this easy, sending HTML-based attachments and messages (using the mail ( ) character extraction, encoding and formatting) requires developers to write similar gray code. .
Additionally, the mail() function requires a local mail server to deliver messages. PHPMailer can use a non-local mail server (SMTP) if you have an authentication certificate.
You can use an email server from another host to send emails, but for this, you need to be authenticated first. For example: To send emails from the Gmail mail server you will need a Gmail account. If you’re going to the Gmail mail server client, you’ll need to run a less secure app.
Pear Mail Set Up
A convention used by email clients to send email is to send a request to an email server. After the email server confirms the email, it sends it to the target email server.
This is a case of sending an email from Gmail’s email server on your end. You don’t need to block a local mail server to run the code. We will use the SMTP convention:
CREATE TABLE `smtp_details` (`smtp_id` int(11) NOT NULL, `server_name` varchar(100) NOT NULL, `cript_type` varchar(10)) NOT NULL, `port_no` int(5)) NOT NULL, varchar` er ( 150) NOT NULL, `password` varchar(150) NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=latin1;
Create an HTML form to receive SMTP data from the front end. This form includes the server name, port number, encryption type, and username and password of the SMTP connection.
