title: php function to echo javascript string
body: <p>Is the a proper php function to echo javascript string?<br>
  I want to the php function to echo something like this:</p>
  
  <pre><code>&lt;!--/* OpenX Interstitial or Floating DHTML Tag v2.8.7 */--&gt;
  &lt;script type="text/javascript"&gt;// &lt;![CDATA[
  //&lt;![CDATA[
  var ox_u = 'extremely_long_url_string';
  if (document.context) ox_u += '&amp;context=' + escape(document.context);
  document.write("&lt;scr"+"ipt type='text/javascript' src='" + ox_u + "'&gt;&lt;/scr"+"ipt&gt;");
  //
  // ]]&gt;&lt;/script&gt;
  </code></pre>
  
  <p>I know I can put it all in one line and use \ to escape all the quotes BUT I'm looking for a more elegant &amp; effective solution.</p>
