_parseEmail()

protected string _parseEmail ( array $matches )

Support callback for parsing email addresses.

Parameters

  • (array) $matches: Matches from preg_replace_callback().

Returns

  • (string) An obfuscated mailto anchor.

Description

Support callback for parsing email addresses.

From the original notes ...

Input: an email address, for example "foo@example.com"

Output: the email address as a mailto link, with each character of the address encoded as either a decimal or hex entity, in the hopes of foiling most address harvesting spam bots. For example:

<a href="&#x6D;&#97;&#105;&#108;&#x74;&#111;:&#102;&#111;&#111;&#64;&#101;
x&#x61;&#109;&#x70;&#108;&#x65;&#x2E;&#99;&#111;&#109;">&#102;&#111;&#111;
&#64;&#101;x&#x61;&#109;&#x70;&#108;&#x65;&#x2E;&#99;&#111;&#109;</a>
