Process Specific Range Row During Insert CSV file in MYSQL Database - php

Question

I am trying to insert data from csv to MYSQL database like below and its working fine
$file = fopen('../assets/uploads/'.$file_name, "r");
while (($column = fgetcsv($file, 10000, ",")) !== FALSE) {
$fname = "";
if (isset($column[0])) {
$fname = mysqli_real_escape_string($mysqli, $column[0]);
}
$lname = "";
if (isset($column[1])) {
$lname = mysqli_real_escape_string($mysqli, $column[1]);
}
$email = "";
if (isset($column[2])) {
$email = mysqli_real_escape_string($mysqli, $column[2]);
}
$sqlInsert = "INSERT into $lead_data_table (lfname,llname,lemail,lead_id,lead_user_id) VALUES (?,?,?,?,?)";
$stmt = $mysqli->prepare($sqlInsert);
$stmt->bind_param('sssii', $fname, $lname,$email,$lead_insert_id,$lead_user_id);
$stmt->execute();
$stmt->close();
$insertId = mysqli_insert_id($mysqli);
However For some reason I want insert data from CSV like 0 to 100 or 100 to Remain All. I am not getting idea how I can do it? Let me know if anyone here can help me for do the same.
Thanks!

Count the csv lines and skip. Something like this will process starting with the hundredth line.
$file = fopen('../assets/uploads/'.$file_name, "r");
$lineCount = 0;
while (($column = fgetcsv($file, 10000, ",")) !== FALSE) {
$lineCount ++;
if ($lineCount >= 100) {
/* process the line */
}
}
And by the way, you're doing your prepared statements correctly. So you don't need to use mysqli_real_escape_string() to mung your data before inserting it.
