title: PHP run multiple function at the same time
body: <p>This is my first application with multi thread concept.</p>
  
  <p>Folder contains the more than 10 flat file, each flat file is 4 gb. </p>
  
  <p>my script nearly took the 1 hrs for 1 flat file, so how to implement the parallel processing, and execute all files in multiple thread. </p>
  
  <p>How i am reading file from folder ?
       just using while loop, call the SP inside while, flat file are the input for the SP.</p>
  
  <p>What i want is : execute all flat file in one shot.</p>
