-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;
-    }
-
-    $info = [
-        'type' => gettype($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':
-            $info += [
-                'object_class' => get_class($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 += [
-                'resource_handle' => (int) $array[$key],
-                'resource_type' => get_resource_type($array[$key]),
-                'resource_refcount' => /* internal resource refcount of $array[$key] */,
-            ];
-            break;
-
-        case 'array':
-            $info += [
-                'array_count' => count($array[$key]),
-            ];
-            break;
-
-        case 'string':
-            $info += [
-                'strlen' => strlen($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
------
-
-To enable the extension from source, run:
-
-```
-    phpize
-    ./configure
-    make
-    sudo make install
-```
