Create MySQL Database for PHP Web Spider Extracted Emails Addresses (4)

store extracted email to database

In this final part of PHP/cURL email extractor, I will show you how to store extracted data into MySQL database. You can store email addresses and contact information collected not just from one website, but also from various websites into the same database.

You might want to store email collected based on your purpose. For example, if you have a real estate website and a internet shopping website, then information collected should be stored into two different categories (tables in MySQL database).

First, you need to activate XAMPP on your PC, both Apache and MySQL. At browser URL, go to "http://localhost/phpmyadmin/". Go to top menu bar and select "Database". To create a new database for our tutorial, enter "email_collection" and press "Create" button, as shown in the picture below.

You can download the source file for PHP cURL Email Extractor from here.

PHP Email Extractor Script with cURL and Regular Expression (2)

targeted email extractor

In this post, we need to make a small modification to previous PHP script for targeted email extraction.

First, we need to revisit the source file of the targeted web page, we can see that there are repeated blocks of agent contacts, with name, email and phone number. Total of 10 blocks per page. 

The plan is to use the script to "cut out" each block and stores into array, then extract name, email and phone number from each block.

As you can see, each block starts with <div class="negotiators-wrapper"> tag and ends with </div></div>. Note that both </div> tags are separated by carriage return and new line feed in this example.

Email Extractor Script with PHP cURL and Regular Expression (1)

email spider

In this post, I will explain how to use PHP/cURL to extract / harvest email addresses from websites. The script will involve regular expression to match HTML tag for extraction.

If we send out email and address the person as "Dear Sir" or "Dear Madam", most likely the email will end up as spam. We do not want to just extract email addresses only, but also other information related to the email addresses, such as name, telephone, company, job position etc. When we send out email from the list collected, we want to be able to address the contact person as detail as possible, such as with his/her name, job position in the company, contact number etc.

Of course, please do not abuse the ability of email extraction and send out unwanted spam mails, products/services advertising, violate copyright law or disturbing network bandwidth etc. If you get into trouble, talk to your lawyer please.
