-
-This simple library provides functionality for [`array_column()`](http://php.net/array_column)
-to versions of PHP earlier than 5.5. It mimics the functionality of the built-in
-function in every way.
-
-
-## Usage
-
-```
-array array_column(array $input, mixed $columnKey[, mixed $indexKey])
-```
-
-Given a multi-dimensional array of data, `array_column()` returns the values
-from a single column of the input array, identified by the `$columnKey`.
-Optionally, you may provide an `$indexKey` to index the values in the returned
-array by the values from the `$indexKey` column in the input array.
-
-For example, using the following array of data, we tell `array_column()` to
-return an array of just the last names, indexed by their record IDs.
-
-``` php
-<?php
-$records = array(
-    array(
-        'id' => 2135,
-        'first_name' => 'John',
-        'last_name' => 'Doe'
-    ),
-    array(
-        'id' => 3245,
-        'first_name' => 'Sally',
-        'last_name' => 'Smith'
-    ),
-    array(
-        'id' => 5342,
-        'first_name' => 'Jane',
-        'last_name' => 'Jones'
-    ),
-    array(
-        'id' => 5623,
-        'first_name' => 'Peter',
-        'last_name' => 'Doe'
-    )
-);
-
-$lastNames = array_column($records, 'last_name', 'id');
-```
-
-If we call `print_r()` on `$lastNames`, you'll see a resulting array that looks
-a bit like this:
-
-``` text
-Array
-(
-    [2135] => Doe
-    [3245] => Smith
-    [5342] => Jones
-    [5623] => Doe
-)
-```
-
-
-## Installation
-
-The easiest way to install this library is to use [Composer](https://getcomposer.org/):
-
-```
-php composer.phar require ramsey/array_column
-```
-
-Then, when you run `composer install`, everything will fall magically into place,
-and the `array_column()` function will be available to your project, as long as
-you are including Composer's autoloader.
-
-_However, you do not need Composer to use this library._
-
-This library has no dependencies and should work on older versions of PHP.
-Download the code and include `src/array_column.php` in your project, and all
-should work fine.
-
-When you are ready to run your project on PHP 5.5, everything should
-continue to run well without conflicts, even if this library remains included
-in your project.

 CHANGELOG
 =========
 
+3.4.0
+-----
+
+ * added `SHELL_VERBOSITY` env var to control verbosity
+ * added `CommandLoaderInterface`, `FactoryCommandLoader` and PSR-11
+   `ContainerCommandLoader` for commands lazy-loading
+ * added a case-insensitive command name matching fallback
+ * added static `Command::$defaultName/getDefaultName()`, allowing for
+   commands to be registered at compile time in the application command loader.
+   Setting the `$defaultName` property avoids the need for filling the `command`
+   attribute on the `console.command` tag when using `AddConsoleCommandPass`.
+
+3.3.0
+-----
+
+* added `ExceptionListener`
+* added `AddConsoleCommandPass` (originally in FrameworkBundle)
+* [BC BREAK] `Input::getOption()` no longer returns the default value for options
+  with value optional explicitly passed empty
+* added console.error event to catch exceptions thrown by other listeners
+* deprecated console.exception event in favor of console.error
+* added ability to handle `CommandNotFoundException` through the 
+ `console.error` event
+* deprecated default validation in `SymfonyQuestionHelper::ask`
+
+3.2.0
+------
+
+* added `setInputs()` method to CommandTester for ease testing of commands expecting inputs
+* added `setStream()` and `getStream()` methods to Input (implement StreamableInputInterface)
+* added StreamableInputInterface
+* added LockableTrait
+
+3.1.0
+-----
+
+ * added truncate method to FormatterHelper
+ * added setColumnWidth(s) method to Table 
+
 2.8.3

+/**
+ * A generic ErrorHandler for the PHP engine.
+ *
+ * Provides five bit fields that control how errors are handled:
+ * - thrownErrors: errors thrown as \ErrorException
+ * - loggedErrors: logged errors, when not @-silenced
+ * - scopedErrors: errors thrown or logged with their local context
+ * - tracedErrors: errors logged with their stack trace
+ * - screamedErrors: never @-silenced errors
+ *
+ * Each error level can be logged by a dedicated PSR-3 logger object.
+ * Screaming only applies to logging.
+ * Throwing takes precedence over logging.
+ * Uncaught exceptions are logged as E_ERROR.
+ * E_DEPRECATED and E_USER_DEPRECATED levels never throw.
+ * E_RECOVERABLE_ERROR and E_USER_ERROR levels always throw.
+ * Non catchable errors that can be detected at shutdown time are logged when the scream bit field allows so.
+ * As errors have a performance cost, repeated errors are all logged, so that the developer
+ * can see them and weight them as more important to fix than others of the same level.

+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;
+
+        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
+-----
+
+To enable the extension from source, run:
+
+```
+    phpize
+    ./configure
+    make
+    sudo make install
+```

 CHANGELOG
 =========
 
+3.4.0
+-----
+
+  * Implementing `TraceableEventDispatcherInterface` without the `reset()` method has been deprecated.
+
+3.3.0
+-----
+
+  * The ContainerAwareEventDispatcher class has been deprecated. Use EventDispatcher with closure factories instead.
+
+3.0.0
+-----
+
+  * The method `getListenerPriority($eventName, $listener)` has been added to the
+    `EventDispatcherInterface`.
+  * The methods `Event::setDispatcher()`, `Event::getDispatcher()`, `Event::setName()`
+    and `Event::getName()` have been removed.
+    The event dispatcher and the event name are passed to the listener call.
+
 2.5.0
