Solution : Use mysql script instead of import form from phpmyadmin (that will save you a lot of time)
Script :
LOAD DATA LOCAL INFILE 'file_name.csv' INTO TABLE table_name FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n' (column1,column2,column3);
Note : place your csv file in your phpmyadmin directory
