title: file_put_contents() not working
body: <p>I want to save the contents in the file in <code>order.dat</code> and <code>now</code> I'm using this PHP script:</p>
  
  <pre><code>&lt;?php
  $a_str = array( 
    "orderid"=&gt;"175", 
    "txnid"=&gt;"RC456456456", 
    "date"=&gt;"54156456465", 
    "amount"=&gt;"109$" 
  ); 
  
  $file = 'order.txt';
  $contents = implode(PHP_EOL, $a_str);
  //$contents = $orderid.'|'.$txnid.'|'.$date.'|'.$amount;
  $contents .= PHP_EOL . PHP_EOL;
  file_put_contents($file, $contents);
  print("|$contents|");
  ?&gt;
  </code></pre>
  
  <p>How it is possible to save the data in <code>order.dat</code> file in this format?</p>
  
  <pre><code>175|RC456456456|54156456465|109$|
