Reading emails from gmail using PHP & IMAP

Recently i have worked on language translation project for that i need to read emails using PHP From the gamil inbox based on the email content i had created projects in the database…fortunately reading email from the gmail was easier than i think thanks to IMAP extension.

Here is the simple example for retrieving emails from the gmail:

NOTE: This will work only if you meet the fallowing requirements

  • PHP version should be PHP5 or latest
  • PHP IMAP Extension should be enabled in your PHP installation
  • IMAP should be enabled in your Gmail settings.

How to enable IMAP in PHP

How to Enable IMAP in XAMPP

IMAP is not enabled by default in Xampp distribution, so to enable it go to the file "\xampp\php\php.ini" and search for ";extension=php_imap.dll" and by removing the beginning semicolon at the line ,it’s get enabled ,it should be: extension=php_imap.dll.

How to enable IMAP in Linux

You can install the PHP5 IMAP module with this command :

apt-get install php5-imap

However it’s not enabled by default so enable it with:

php5enmod imap

To see the changes ,restart Apache

service apache2 restart

Here is the PHP script for retrieve Your Gmail Emails Using IMAP.

    Hi arjun, your code works nice. However I want to retrieve entire body text. Currently it just retrieves a small part of the message text. What should I do to get the entire message body of the email?

    Hello guys,

    I have implemented Gmail Imap thing and working fine but I have 1 question, is there any option to use datetime in imap_search function. I mean currently I am using this like

    imap_search($kImap->mailbox,’SINCE 03 August 2017′);

    but i want to use this like

    imap_search($kImap->mailbox,’SINCE 03 August 2017 10:00′);

    So basically i want to import all the email that was there in Gmail since 03 August 2017 10:00

    Thanks,
    Ajay

    • I guess you can only pass date, not date time

      • Ajay

        Hi Arjun.

        Thanks for your reply, well is there any other way by which we can fetch email received as per datetime? Actually we are receiving too many emails in our Gmail inbox and i learn that if we fetch email for entire day then sometimes scripts breaks in between. So to fix this we are planing to schedule a cron script which will run in every 15 min and will fetch all the emails received in last 15 Min. Please suggest

        Thanks,
        Ajay
