+Symfony Debug Extension
+=======================
+
+This extension publishes several functions to help building powerful debugging tools.
+
+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;
+
+        case 'string':
+            $info += array(
+                'strlen' => strlen($array[$key]),
+            );
+            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"]=>
+    array(0) {
+    }
+  }
+  [2]=>
+  array(4) {
+    ["file"]=>
+    string(102) "foo.php"
+    ["line"]=>
+    int(2)
+    ["function"]=>
+    string(3) "bar"
+    ["args"]=>
+    array(0) {
+    }
+  }
+}
+*/
+```
+
+Usage
+-----
+
+The extension is compatible with ZTS mode, and should be supported by PHP5.3, 5.4, 5.5 and 5.6.
+To enable the extension from source, run:
+
+```
+    phpize
+    ./configure
+    make
+    sudo make install
+```
