title: What's the difference between compiling a PHP extension from php/php-src and PECL?
body: <p>Is there any difference between downloading and compiling a PHP extension from php/php-src (GitHub) or PECL?</p>
  
  <p>I can clone php/php-src <code>checkout php-5.5.30</code> and build memcached extension. I can do the same with <code>pecl download memcached</code> and build from tha tarball. Would I get the same exact <code>.so</code> module?</p>
