title: Can't get php errors to show when `error_reporting` set to `E_ALL`
body: <p>I have WAMP with php 5.4.12 and I want to report errors.</p>
  
  <p>My <code>php.ini</code> contains the following:</p>
  
  <pre><code>; Common Values:
  ;   E_ALL &amp; ~E_NOTICE  (Show all errors, except for notices and coding standards warnings.)
  ;   E_ALL &amp; ~E_NOTICE | E_STRICT  (Show all errors, except for notices)
  ;   E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR  (Show only errors)
  ;   E_ALL | E_STRICT  (Show all errors, warnings and notices including coding standards.)
  ; Default Value: E_ALL &amp; ~E_NOTICE
  ; Development Value: E_ALL | E_STRICT
  ; Production Value: E_ALL &amp; ~E_DEPRECATED
  ; http://php.net/error-reporting
  error_reporting = E_ALL
  </code></pre>
  
  <p>but no errors are showing.</p>
  
  <p>What value should <code>error_reporting</code> take and how can I retrieve the reported errors?</p>
