Passing SMTP Username & Password in php.ini - A How-To Guide

If you are looking to configure your PHP application to send emails using SMTP, you will need to provide your SMTP server's credentials, including the SMTP username and password. One way to do this is by passing the credentials directly in the php.ini file. In this how-to guide, we will walk you through the steps to accomplish this task.

  1. Step 1: Locate your php.ini file
  2. Step 2: Open php.ini file
  3. Step 3: Locate the mail settings section
  4. Step 4: Add SMTP credentials
  5. Step 5: Save the changes

Step 1: Locate your php.ini file

The first step is to locate the php.ini file on your server. The location of this file may vary depending on your server configuration, but it is typically located in the /etc/ folder. If you are unsure of the file's location, you can run the following command in your terminal:

php -i | grep "Loaded Configuration File"

Step 2: Open php.ini file

Once you have located the php.ini file, open it in your preferred text editor.

Step 3: Locate the mail settings section

Next, locate the mail settings section in the php.ini file. This section is typically located towards the bottom of the file, and it will look something like this:

[mail function]
; For Win32 only.
; http://php.net/smtp
SMTP = localhost
smtp_port = 25

; For Win32 only.
; http://php.net/sendmail-from
sendmail_from = me@example.com

Step 4: Add SMTP credentials

Now that you have located the mail settings section, you can add your SMTP server's credentials. Add the following lines to the php.ini file:

[mail function]
; For Win32 only.
; http://php.net/smtp
SMTP = smtp.example.com
smtp_port = 587
auth_username = your_smtp_username
auth_password = your_smtp_password

; For Win32 only.
; http://php.net/sendmail-from
sendmail_from = me@example.com

Replace smtp.example.com with your SMTP server's hostname, and replace your_smtp_username and your_smtp_password with your SMTP server's username and password, respectively.

Step 5: Save the changes

Once you have added your SMTP credentials to the php.ini file, save the changes and exit the text editor.

That's it! You have successfully passed your SMTP server's credentials in the php.ini file, and your PHP application should now be able to send emails using SMTP.
