title: PHP Apache Enable multiprocess/thread
body: <p>Well, I have a web application with multiple tools.
  One such tool sends a simple Ajax request at the same PHP script, which in turn sends an HTTP request via Curl, but the problem is that this request takes a long time.</p>
  
  <p>As this process takes a long time, I can not perform other tasks within the application, so I expect to complete the process in order to use other tools.</p>
  
  <p>How I can assign or enable PHP to use multiple children or processes?</p>
  
  <p>In this particular case, I don't need and don't want to use Thread Class, or "exec" for execute via command line.</p>
  
  <p><strong>Explanation of the problem:</strong></p>
  
  <p>I have script for upload file, but when I upload file(<em>with big size</em>), this script take a long time, so while loading the file, I would like to see my history of uploaded files.
  To this should open another tab in the browser with the URL history uploads.
  The problem is that when I open the record, this is left "waiting" until the other tab finishes loading (<em>when finished upload the file</em>).</p>
  
  <p>(<em>I thing</em>)The problem is that PHP handles all in the same process/thread and this prevents you use multiple script at once(<em>with multiples tab on browser</em>).</p>
  
  <p>So my problem is that I need to run multiple processes at the same time, without waiting for any of the process finishes running.</p>
  
  <p>I am currently working with Linux Centos 7 servers, with Apache + PHP 5.4 and 4GB of RAM allocated to PHP.</p>
  
  <p>Thanks</p>
