Import certain csv/excel data to mysql database using PHP - php

Question

Is there any way to select a certain csv/excel cells then import its data to database? I have a similar program but it only import the first, second, etc. columns.
So here's the php codes for reading excel data and input.
<?php
include 'db.php';
if(isset($_POST["Import"])){
echo $filename=$_FILES["file"]["tmp_name"];
if($_FILES["file"]["size"] > 0)
{
$file = fopen($filename, "r");
while (($emapData = fgetcsv($file, 10000, ",")) !== FALSE)
{
//It wiil insert a row to our subject table from our csv file`
$sql = "INSERT into subject (`SUBJ_CODE`, `SUBJ_DESCRIPTION`, `UNIT`, `PRE_REQUISITE`,COURSE_ID, `AY`, `SEMESTER`)
values('$emapData[1]','$emapData[2]','$emapData[3]','$emapData[4]','$emapData[5]','$emapData[6]','$emapData[7]')";
//we are using mysql_query function. it returns a resource on true else False on error
$result = mysqli_query( $conn, $sql );
if(! $result )
{
echo "<script type=\"text/javascript\">
alert(\"Invalid File:Please Upload CSV File.\");
window.location = \"index.php\"
</script>";
}
}
fclose($file);
//throws a message if data successfully imported to mysql database from excel file
echo "<script type=\"text/javascript\">
alert(\"CSV File has been successfully Imported.\");
window.location = \"index.php\"
</script>";
//close of connection
mysqli_close($conn);
}
}
?>
It only import the selected columns

If you want to do it for just once than you can use some online tools.
If you want to have a code for this than you can do by following code
$open = fopen("filename.csv", "r"); // This will open the file for you
$data = fgetcsv($Open, 1000, ","); // Read Line be Line
while (($data = fgetcsv($Open, 1000, ",")) !== FALSE)
{
// Read the data
}
