import .CSV file with PHP using PDO - php

Question

I'm having a problem importing .CSV data into a SQL database. I'm trying to use PDO in my PHP file to accomplish this and I can't seem to figure this out.
if (isset($_FILES['uploadedfile'])) {
// get the csv file and open it up
$file = $_FILES['uploadedfile']['tmp_name'];
$handle = fopen($file, "r");
try {
// prepare for insertion
$query_ip = $db->prepare('
INSERT INTO projects (
id, project_name, contact, pm, apm,
est_start, est_end, trips, tasks, perc_complete,
bcwp, actual, cpi, bcws, bac,
comments, status, project_revenue, profit_margin, pm_perc,
audited, account_id
) VALUES (
?, ?, ?, ?, ?,
?, ?, ?, ?, ?,
?, ?, ?, ?, ?,
?, ?, ?, ?, ?,
?, ?
)');
$data = fgetcsv($handle,1000,",","'");
$query_ip->execute($data);
$count = $query_ip->rowCount();
fclose($handle);
} catch(PDOException $e) {
die($e->getMessage());
}
echo 'Projects imported ' . $count . ' rows were affected';
} else {
echo 'Could not import projects';
}
Now this works, kind of. It imports the data but as you may have guessed this is only inserting the first row of the .CSV file, which by the way is the column headers. So I need to skip the first row and loop through the rest of this .CSV file.
Obviously throwing me some code would solve this, but more than that I would like an explanation of how to do this properly with PHP Data Objects (PDO). All the examples I've come across either have huge flaws or don't use PDO. Any and all help is welcomed and appreciated.

The comments helped me come up with this answer. I used the following code
if (isset($_FILES['uploadedfile'])) {
// get the csv file and open it up
$file = $_FILES['uploadedfile']['tmp_name'];
$handle = fopen($file, "r");
try {
// prepare for insertion
$query_ip = $db->prepare('
INSERT INTO projects (
id, project_name, contact, pm, apm,
est_start, est_end, trips, tasks, perc_complete,
bcwp, actual, cpi, bcws, bac,
comments, status, project_revenue, profit_margin, pm_perc,
audited
) VALUES (
?, ?, ?, ?, ?,
?, ?, ?, ?, ?,
?, ?, ?, ?, ?,
?, ?, ?, ?, ?,
?
)
');
// unset the first line like this
fgets($handle);
// created loop here
while (($data = fgetcsv($handle, 1000, ',')) !== FALSE) {
$query_ip->execute($data);
}
fclose($handle);
} catch(PDOException $e) {
die($e->getMessage());
}
echo 'Projects imported';
} else {
echo 'Could not import projects';
}
I hope this helps future readers properly import their .CSV files using PDO. It should be noted this should not be used on a live server/site. This code has 0 protection against potentially harmful uploads.
