I need to do it for a huge CSV file with help of PHP.

Answer 1

Use fgetcsv function. It gets a line from file pointer and parse for CSV fields.

Following example reads a CSV file myfile.csv, gets the records and displays them line by line.

<?php
$row = 1;
//open the file
if (($handle = fopen("myfile.csv", "r")) !== FALSE)
{
    while (($data = fgetcsv($handle, 0, ",")) !== FALSE)
    {
        $num = count($data);
        echo "<p> $num fields in line $row: <br /></p>\n";
        $row++;
        for ($c=0; $c < $num; $c++)
        {
            echo $data[$c] . "<br />\n";
        }
    }
    fclose($handle);
}
?>
