Im working on a script to tear into a csv file and ive got the rows separated, but im not sure how to assign variables to the fields within the row, so that i can perform functions with them.

my code:

<?

ini_set('auto_detect_line_endings', true);

$csvraw = file_get_contents("file.csv");

$csv = explode("\n", $csvraw);

$i=0;
foreach($csv AS $key=>$value){

    $rowsplit = explode(",", $value);

// This is where i get my headers
    if($i == 0){
        $col0 = $rowsplit[0];
        $col1 = $rowsplit[1];
        $col2 = $rowsplit[2];
        $col3 = $rowsplit[3];
        $col4 = $rowsplit[4];
        $col5 = $rowsplit[5];
        $col6 = $rowsplit[6];
        $col7 = $rowsplit[7];
    }

    $i++;

//This is where i loop through each row's fields

    foreach($rowsplit AS $key2=>$value2){

        if(empty($value2)){
            echo "";
        }else{
            echo "$value2 <br>";
        }

// This is where i need to assign $variable0 through $variable7 so i can perform a function with the field values.

    }

    echo "<br><br><br>";

}

?>
