 Debug Component
 ===============
 
-Debug provides tools to make debugging easier.
-
-Enabling all debug tools is as easy as calling the `enable()` method on the
-main `Debug` class:
-
-```php
-use Symfony\Component\Debug\Debug;
-
-Debug::enable();
-```
-
-You can also use the tools individually:
-
-```php
-use Symfony\Component\Debug\ErrorHandler;
-use Symfony\Component\Debug\ExceptionHandler;
-
-if ('cli' !== php_sapi_name()) {
-    ini_set('display_errors', 0);
-    ExceptionHandler::register();
-} elseif (!ini_get('log_errors') || ini_get('error_log')) {
-    ini_set('display_errors', 1);
-}
-ErrorHandler::register($errorReportingLevel);
-```
-
-Note that the `Debug::enable()` call also registers the debug class loader
-from the Symfony ClassLoader component when available.
-
-This component can optionally take advantage of the features of the HttpKernel
-and HttpFoundation components.
+The Debug component provides tools to ease debugging PHP code.
 
 Resources
 ---------

-    $ cd path/to/Symfony/Component/Debug/
-    $ composer.phar install --dev

+Symfony Debug Extension for PHP 5
+=================================
+
+This extension publishes several functions to help building powerful debugging tools.
+It is compatible with PHP 5.3, 5.4, 5.5 and 5.6; with ZTS and non-ZTS modes.
+It is not required thus not provided for PHP 7.
+
+symfony_zval_info()
+-------------------
+
+- exposes zval_hash/refcounts, allowing e.g. efficient exploration of arbitrary structures in PHP,
+- does work with references, preventing memory copying.
+
+Its behavior is about the same as:
+
+```php
+<?php
+
+function symfony_zval_info($key, $array, $options = 0)
+{
+
+    // $options is currently not used, but could be in future version.
+
+    if (!array_key_exists($key, $array)) {
+        return null;
+    }
+
+    $info = array(
+        'type' => gettype($array[$key]),
+        'zval_hash' => /* hashed memory address of $array[$key] */,
+        'zval_refcount' => /* internal zval refcount of $array[$key] */,
+        'zval_isref' => /* is_ref status of $array[$key] */,
+    );
+
+    switch ($info['type']) {
+        case 'object':
+            $info += array(
+                'object_class' => get_class($array[$key]),
+                'object_refcount' => /* internal object refcount of $array[$key] */,
+                'object_hash' => spl_object_hash($array[$key]),
+                'object_handle' => /* internal object handle $array[$key] */,
+            );
+            break;
+
+        case 'resource':
+            $info += array(
+                'resource_handle' => (int) $array[$key],
+                'resource_type' => get_resource_type($array[$key]),
+                'resource_refcount' => /* internal resource refcount of $array[$key] */,
+            );
+            break;
+
+        case 'array':
+            $info += array(
+                'array_count' => count($array[$key]),

+            break;
+

+            );
+            break;
+    }
+
+    return $info;
+}
+```
+
+symfony_debug_backtrace()
+-------------------------
+
+This function works like debug_backtrace(), except that it can fetch the full backtrace in case of fatal errors:
+
+```php
+function foo() { fatal(); }
+function bar() { foo(); }
+
+function sd() { var_dump(symfony_debug_backtrace()); }
+
+register_shutdown_function('sd');
+
+bar();
+
+/* Will output
+Fatal error: Call to undefined function fatal() in foo.php on line 42
+array(3) {
+  [0]=>
+  array(2) {
+    ["function"]=>
+    string(2) "sd"
+    ["args"]=>
+    array(0) {
+    }
+  }
+  [1]=>
+  array(4) {
+    ["file"]=>
+    string(7) "foo.php"
+    ["line"]=>
+    int(1)
+    ["function"]=>
+    string(3) "foo"
+    ["args"]=>

+    string(3) "bar"
+    ["args"]=>
+    array(0) {
+    }
+  }
+}
+*/
