Convert CSV to SQL INSERT statements

convert_csv_to_sql.php

<?php
$file = $argv[1];
$table = $argv[2];

$ls = file($file);

$out = "";

foreach ($ls as $l) {
  $d = str_getcsv(trim($l));
  $q = sprintf('INSERT INTO `%s` VALUES ("%s");', $table, implode('","', $d)).PHP_EOL;
  echo $q;
  $out .= $q;
}

file_put_contents($table.'.sql', $out);

I want to skip or ignore the first line, which is the header, how do I go about that?
