exclude row 1 when importing CSV file to MYSQL using php

Question

I have the following code that imports a CSV file into MYSQL table. The only problem is that it also import the header row. How can I alter the below code so that it doesn't include the top row.

I looked around and found 'IGNORE 1 LINES', but have yet to get it working.

Also, what does that '500' mean?

//connect to mysql database
$connection = mysqli_connect($hostname, $username, $password, $database) or die("Error " . mysqli_error($connection));

// open the csv file
$fp = fopen($filename,"r");

//parse the csv file row by row
while(($row = fgetcsv($fp,"500",",")) != FALSE)
{
    //insert csv data into mysql table
    $sql = "INSERT INTO table92108 (date,filename,directory,type,email) VALUES('" . implode("','",$row) . "')";
    if(!mysqli_query($connection, $sql))
    {
        die('Error : ' . mysqli_error());
    }
}

fclose($fp);

//close the db connection
mysqli_close($connection);
?>

Here is my second attempt based on answer below, but still doesn't work. What did I do wrong???

//connect to mysql database
$connection = mysqli_connect($hostname, $username, $password, $database) or die("Error " . mysqli_error($connection));

// open the csv file
$fp = fopen($filename,"r");

//parse the csv file row by row
$count = 0;
while (($row = fgetcsv($fp, 500, ",")) !== FALSE) {
    $count++;
    if ($count == 1) { continue; }

{
    //insert csv data into mysql table
    $sql = "INSERT INTO table92108 (date,filename,directory,type,email) VALUES('" . implode("','",$row) . "')";
    if(!mysqli_query($connection, $sql))
    {
        die('Error : ' . mysqli_error());
    }
}

fclose($fp);

//close the db connection
mysqli_close($connection);

Answer 1

I used that class for import csv file.

**Quick_CSV_import.php**

<?php 


class Quick_CSV_import 
{ 
  var $table_name; //where to import to 
  var $file_name; //where to import from 
  var $use_csv_header; //use first line of file OR generated columns names 
  var $field_separate_char; //character to separate fields 
  var $field_enclose_char; //character to enclose fields, which contain separator char into content 
  var $field_escape_char; //char to escape special symbols 
  var $error; //error message 
  var $arr_csv_columns; //array of columns 
  var $table_exists; //flag: does table for import exist 
  var $encoding; //encoding table, used to parse the incoming file. Added in 1.5 version 

  function Quick_CSV_import($file_name="") 
  { 
    $this->file_name = $file_name; 
    $this->arr_csv_columns = array(); 
    $this->use_csv_header = true; 
    $this->field_separate_char = ",";

  function import()

    $this->table_exists = false; 
    $this->create_import_table(); 

    if(empty($this->arr_csv_columns))

  function get_encodings()

    if(mysql_num_rows($res) > 0)

  //defines the encoding of the server to parse to file

    $res = @mysql_query($sql);

  /* change end */ 

} 

?> 

here is example

if(!isset($_POST["encoding"]))

if(isset($_POST["Go"]) && ""!=$_POST["Go"]) //form was submitted 
{ 
  $csv->file_name = $HTTP_POST_FILES['file_source']['tmp_name']; 

  //optional parameters

  //start import now
