title: Problem xdebug for PHP 7.3.12-1+ubuntu16.04.1
body: <p>I built according to <a href="https://xdebug.org/docs/install" rel="nofollow noreferrer">https://xdebug.org/docs/install</a> from source, since pecl/pearl is broken:</p>
  
  <pre><code>pecl install xdebug
  downloading xdebug-2.8.0.tgz ...
  Starting to download xdebug-2.8.0.tgz (238,122 bytes)
  .................................................done: 238,122 bytes
  PHP Fatal error:  Cannot use result of built-in function in write context in /usr/share/php/Archive/Tar.php on line 639
  </code></pre>
  
  <p>After building, lib is in <code>/usr/lib/php/20180731/xdebug.so</code>.
  I added in <code>/etc/php/7.3/apache2/php.ini</code>:</p>
  
  <pre><code>[opcache]
  ...
  [xdebug]
  zend_extension=~"/usr/lib/php/20180731/xdebug.so"
  xdebug.remote_enable = 1
  xdebug.remote_autostart = 1
  </code></pre>
  
  <p>I restarted apache: <code>service apache2 restart</code><br>
  I checked with <code>service apache2 status</code>.</p>
  
  <p>When I run <code>php -m</code>, it shows</p>
  
  <pre><code>[Zend Modules]
  Zend OPcache
  </code></pre>
  
  <p>but no XDebug.
  Output of <code>php --version</code> is:</p>
  
  <pre><code>PHP 7.3.12-1+ubuntu16.04.1+deb.sury.org+1 (cli) (built: Nov 28 2019 07:36:56) ( NTS )

  <p>No XDebug also.
  So now I can't get XDebug to work with Visual Studio Code.
  Any ideas? Many thanks</p>
