This extension may be part of the PHP distribution (compiled-in), otherwise it needs to be loaded dynamically. Its name is probably <em>mysqli.so</em> or <em>php_mysqli.dll</em>. phpMyAdmin tried to load the extension but failed. Usually, the problem is solved by installing a software package called “PHP-MySQL” or something similar.</p> <p>There was two interfaces PHP provided as MySQL extensions - <code class="docutils literal notranslate"><span class="pre">mysql</span></code> and <code class="docutils literal notranslate"><span class="pre">mysqli</span></code>. The <code class="docutils literal notranslate"><span class="pre">mysql</span></code> interface was removed in PHP 7.0.</p> <p>This problem can be also caused by wrong paths in the <code class="file docutils literal notranslate"><span class="pre">php.ini</span></code> or using wrong <code class="file docutils literal notranslate"><span class="pre">php.ini</span></code>.</p> <p>Make sure that the extension files do exist in the folder which the <code class="docutils literal notranslate"><span class="pre">extension_dir</span></code> points to and that the corresponding lines in your <code class="file docutils literal notranslate"><span class="pre">php.ini</span></code> are not commented out (you can use <code class="docutils literal notranslate"><span class="pre">phpinfo()</span></code> to check current setup):</p> <div class="highlight-ini notranslate"><div class="highlight"><pre><span></span><span class="k">[PHP]</span> <span class="c1">; Directory in which the loadable extensions (modules) reside.</span> <span class="na">extension_dir</span><span class="w"> </span><span class="o">=</span><span class="w"> </span><span class="s">"C:/Apache2/modules/php/ext"</span> </pre></div> </div> <p>The <code class="file docutils literal notranslate"><span class="pre">php.ini</span></code> can be loaded from several locations (especially on Windows), so please check you’re updating the correct one.
