title: php composer.phar update does not work with Symfony install
body: <p>I'm running WAMP on Windows 7 64 Bits.
  The <code>PATH</code> variable is set to <code>c:\wamp\bin\php\php5.3.13\</code></p>
  
  <p>&nbsp;</p>
  
  <p>I'm trying to install Symfony and I do not understand why first line runs and not the second:</p>
  
  <p>This runs successfully:</p>
  
  <pre>php c:\wamp\bin\php\php5.3.13\composer.phar update</pre>
  
  <p>&nbsp;<br>
  This line fails:</p>
  
  <pre>php composer.phar update</pre>
  
  <p>With the error:  </p>
  
  <blockquote>
    <p>"Could not open input file: composer.phar"</p>
  </blockquote>
  
  <p>What can explain this?</p>
  
  <p>&nbsp;<br>
  <code>get_include_path</code> returns : `</p>
  
  <blockquote>
    <p>.;C:\wamp\bin\php\php5.3.13\php\PEAR`.</p>
  </blockquote>
  
  <p><br/>Does this mean that if composer.phar is not in PEAR directory 'php composer.phar update' will not work?</p>
