Uploading images and inserting filename to MySQL - php

Question

xxxHow can I fix this script so that it actually posts 3 separate images rather than the same image 3 times. Any help would be much appreciated. I will provide the code html code to encase that's relevant.
html:
<form method="post" action="insert.php" enctype="multipart/form-data">
<input type="text" name="caseName"><br>
<input type="file" name="upload[]"/>
<input type="file" name="upload[]"/>
<input type="file" name="upload[]"/>
<input type="submit" value="Submit" >
</form>
php:
if ( isset( $_FILES['upload'] ) ) {
$name_array = $_FILES['upload']['name'];
$tmp_name_array = $_FILES['upload']['tmp_name'];
for ( $i = 0; $i < count( $name_array ); $i++ ) {
if ( move_uploaded_file( $tmp_name_array[$i], "uploaded/" . $name_array[$i] ) ) {
echo $name_array[$i];
} else {
echo "failed";
}
}
$dsn = 'mysql:host=localhost;dbname=GLO12408958DB';
$username = 'root';
$password = 'yt987210d';
//
// DB connection was made
//
$pdo = new PDO($dsn, $username, $password);
//loop over array to get names. Make sure we have actual content.
if ( count( $name_array ) > 0 && $name_array !== false ) {
//Prepare query
$statement = $pdo->prepare( 'INSERT INTO caseStudies(caseImage,caseImage2,caseImage3) VALUES (?,?,?)' );
//use a different index in the event that the numeric keys in the name array are not ordered correctly
$index = 1;
foreach ( $name_array as $key => $filename ) {
$statement->bindParam( $index, $filename, PDO::PARAM_STR );
$index++;
}
$statement->execute();
//etc....
}
}

According to the manual, bindParam() "Binds a PHP variable to a corresponding named or question mark placeholder in the SQL statement that was used to prepare the statement. Unlike PDOStatement::bindValue(), the variable is bound as a reference and will only be evaluated at the time that PDOStatement::execute() is called."
