    <p>I've been searching the database of questions on the forum, but can not get a solution that is oriented to my question.</p> <p>I come to you, because I doubt has arisen with an autoloader that I'm developing.</p> <p>The point is this, when I try to instantiate a class defined by me the autoloader works fine, but when I try to instantiate a class of the PHP core throws me the following error.</p> <p>For example, when I try to do this:</p> <pre><code>$conn = new PDO (...); </code></pre> <p>Then throws me the following error:</p> <pre><code>Fatal error: Class 'PDO' not found in ... </code></pre> <p>I've noticed that the autoloader is trying to load the class from which I have defined routes to my classes.</p> <p>My question is, how I can do to load a class of the PHP core if I'm using a custom autoloader?</p> <p>I hope you can guide me to solve this problem that I have been presented.</p> <p>In advance thank you very much.</p> <p>Excuse me for not placing the code of custom autoloader, I missed.</p> <p>The code is the same used in symfony but modified and simplified.</p> <pre><code>class ClassLoader { private $prefixes = array (); private $fallbackDirs = array (); private $useIncludePath = false; public function getPrefixes () { return $this-&gt;prefixes; } public function getFallbackDirs () { return $this-&gt;fallbackDirs; } public function addPrefixes ( array $prefixes ) { foreach ( $prefixes as $prefix =&gt; $path ) { $this-&gt;addPrefix ( $prefix, $path ); } } public function addPrefix ( $prefix, $paths ) { if ( !$prefix ) { foreach ( ( array ) $paths as $path ) { $this-&gt;fallbackDirs [] = $path; } return; } if ( isset ( $this-&gt;prefixes [ $prefix ] ) ) { $this-&gt;prefixes [ $prefix ] = array_merge ( $this-&gt;prefixes [ $prefix ], ( array ) $paths ); } else { $this-&gt;prefixes [ $prefix ] = ( array ) $paths; } } public function setUseIncludePath ( $useIncludePath ) { $this-&gt;useIncludePath = $useIncludePath; } public function getUseIncludePath () { return $this-&gt;useIncludePath; } public function register ( $prepend = false ) { spl_autoload_register ( array ( $this, 'loadClass' ) , true, $prepend ); } public function unregister () { spl_autoload_unregister ( array ( $this, 'loadClass' ) ); } public function loadClass ( $class ) { if ( $file = $this-&gt;findFile ( $class ) ) { require $file; return true; } } public function findFile ( $class ) { if ( '\\' == $class [ 0 ] ) { $class = substr ( $class, 1 ); } if ( false !== $pos = strrpos ( $class, '\\' ) ) { // namespaced class name $classPath = str_replace ( '\\', DIRECTORY_SEPARATOR, substr ( $class, 0, $pos ) ) . DIRECTORY_SEPARATOR; $className = substr ( $class, $pos + 1 ); } else { // PEAR-like class name $classPath = null; $className = $class; } $classPath .= str_replace ( '_', DIRECTORY_SEPARATOR, $className ) . '.php'; foreach ( $this-&gt;prefixes as $prefix =&gt; $dirs ) { if ( 0 === strpos ( $class, $prefix ) ) { foreach ( $dirs as $dir ) { if ( file_exists ( $dir . DIRECTORY_SEPARATOR . $classPath ) ) { return $dir . DIRECTORY_SEPARATOR . $classPath; } } } } foreach ( $this-&gt;fallbackDirs as $dir ) { if ( file_exists ( $dir . DIRECTORY_SEPARATOR . $classPath ) ) { return $dir . DIRECTORY_SEPARATOR . $classPath; } } if ( $this-&gt;useIncludePath &amp;&amp; $file = stream_resolve_include_path ( $classPath ) ) { return $file; } } </code></pre> <p>}</p> <p>But if you want to see the original file is here</p> <p><a href="https://github.com/symfony/symfony/blob/master/src/Symfony/Component/ClassLoader/ClassLoader.php" rel="nofollow">https://github.com/symfony/symfony/blob/master/src/Symfony/Component/ClassLoader/ClassLoader.php</a></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
