title: Several error_log() messages on same line in error log
body: <p>I have this PHP code : </p>
  
  <pre><code>error_log('my message 1');
  ....
  error_log('my message 2');
  ...
  error_log('my message 3');
  </code></pre>
  
  <p>This produces in apache error_log one line with all messages : </p>
  
  <pre><code>[Wed Nov 13 17:24:55.880399 2013] [proxy_fcgi:error] [pid xx] [client xxx] AH01071: Got error 'PHP message: my message 1\n'PHP message: my message 2\n'PHP message: my message 3
  </code></pre>
  
  <p>My config : </p>
  
  <pre><code>Apache 2.4
  PHP : 5.4
  PHP-FPM with proxypassmatch directive.
  </code></pre>
  
  <p>My question : Why messages are on the same line, and how to do to have one line per message ?</p>
  
  <p>Thanks for yours answers.</p>
  
  <p>EDIT</p>
  
  <p>One line per message should look like : </p>
  
  <pre><code>[Wed Nov 13 17:24:55.880399 2013] [proxy_fcgi:error] [pid xx] [client xxx] AH01071: Got error 'PHP message: my message 1'
  [Wed Nov 13 17:24:55.880399 2013] [proxy_fcgi:error] [pid xx] [client xxx] AH01071: Got error 'PHP message: my message 2'
  [Wed Nov 13 17:24:55.880399 2013] [proxy_fcgi:error] [pid xx] [client xxx] AH01071: Got error 'PHP message: my message 3'
