title: load csv file content into mysql table with validation
body: <p>i want to import a large csv file (about 12MO) into mysql table , first i tried with LOAD DATA INFILE it work perfectly , but in my case i want firstly test the csv rows to determine if i want to update data or insert new records 
  so the solution is to read the file and compare the content of each row with the data already in the table , and make the right action 
  this methode also works but takes lot of time and resources </p>
  
  <p>now my question is </p>
  
  <p>1 : can i use the import functions of PHPMYADMIN ( open source ) 
      and my project is comercial</p>
  
  <p>2 : if yes i can , do you know some tutorials about this ( any idea )</p>
  
  <p>3 : if no i can't , is there such commercial frameworks for exporting/importing </p>
  
  <p>thanks </p>
