Extract Email Addresses

Just pass the string (e.g. the body part of an email) to the function, and it returns an array of Email Addresses contained in the String.

function extract_emails_from($string) {
         preg_match_all("/[\._a-zA-Z0-9-]+@[\._a-zA-Z0-9-]+/i", $string, $matches);
         return $matches[0];
}

If you catch the return value of function in $emails, you can parse it using foreach:

foreach($emails as $email) {
    echo trim($email).'<br/>';
}

  1. This is more accurate regular expression for email.

    "/[a-z0-9]+[_a-z0-9\.-]*[a-z0-9]+@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})/i"

Posting Code

We highly encourage you to post problematic HTML/CSS/JavaScript over on CodePen and include the link in your post. It's much easier to see, understand, and help with when you do that.

Markdown is supported, so you can write inline code like `<div>this</div>` or multiline blocks of code in in triple backtick fences like this:

```
<script>
  function example() {
    element.innerHTML = "<div>code</div>";
  }
</script>
```
