README

Extract in array ALL valid email addresses from a string or string array. This library also includes a few helper methods to modify the output array.

Installation

composer require donchev/email-extractor

Object Instantiation

EmailExtractor object accept 2 optional parameters in it's __constructor() method:

• array|null $filter An array of words used for filtering matched emails. If not passed to the constructor, an empty array is used when/if filterAsc() or filterDesc() is called.
• string|null $regex A valid regex that match an email address. If not passed to the constructor, the default build-in regex will be used. (NOTE: It is recommended to use the build-in regex, except if you know what you are doing.)

Simple Usage

<?php

require_once __DIR__ . '/vendor/autoload.php';

$extractor = new EmailExtractor();

$content = file_get_contents("email.eml");

$emails = $extractor
    ->extract($content)
    ->export();

Advanced usage

<?php

require_once __DIR__ . '/vendor/autoload.php';

$filter = ['@gmail.com', 'allen']
$content = ["allen@yahoo.com, sample@gmail.com, test@mail.com", "mail@mail.me"];

$extractor = new EmailExtractor($filter);

$emails = $extractor
    ->extractAll($content)
    ->filterInclude()
    ->lower()
    ->unique()
    ->sortDesc()
    ->export();

Output:

array (size=2)
  0 => string 'sample@gmail.com' (length=16)
  1 => string 'allen@yahoo.com' (length=16)

Method chaining design pattern

Email Exporter library uses method chaining. You should follow one simple rule:

• extract() OR extractAll() method SHOULD be called first.

Otherwise, EmailExtractorException will be thrown.

Helper methods

There are a few helper methods build-in. These can be called after extract()/extractAll().
