sqlite to mysql using php - php

Question

I have an application that writes it's data to SQLite everyday. I now want to upload this data into my webhost to use. So I have a scheduled sFTP script to upload the .sqlite file to my webhost and then run another scheduled task to run the php code.
I know that I can use SQLite with PDO but all my other data on the host is in MySQL, so I want to keep everything in the MySQL format.
I have tried writing some php code that will read the sqlite file via PDO and then insert into the MySQL table again with PDO. The script will hopefully run on multiple tables to import so using foreach with Key/Values so I do not have to hardcode every single column in each table (about 30 columns per table)
However I have tried various things but just can not seem to find why the above code does not work problem so asking for help from much better minded users. Please view my code.
Thanks
<?php
ini_set('max_execution_time', 480); //480 seconds = 8 minutes
try {
// Connect to MySQL database
$host = '127.0.0.1';
$db = 'coredb';
$user = 'root';
$pass = 'password';
$charset = 'utf8mb4';
$dsn = "mysql:host=$host;dbname=$db;charset=$charset";
$opt = [
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,
PDO::ATTR_EMULATE_PREPARES => false,
];
$pdomysql = new PDO($dsn, $user, $pass, $opt);
// Connect to SQLite database in file
$file_db = new PDO('sqlite:frp.sqlite');
$file_db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = 'SELECT * from frp_teamdata';
$stmt = $file_db->prepare($sql);
$stmt->execute();
$sqliteresults = $stmt->fetch(PDO::FETCH_ASSOC);

Give this a try:
<?php
ini_set('max_execution_time', 480); //480 seconds = 8 minutes
try {
// Connect to MySQL database
$host = '127.0.0.1';
$db = 'coredb';
$user = 'root';
$pass = 'password';
$charset = 'utf8mb4';
$dsn = "mysql:host=$host;dbname=$db;charset=$charset";
$opt = [
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,
PDO::ATTR_EMULATE_PREPARES => false,
];
$pdomysql = new PDO($dsn, $user, $pass, $opt);
// Connect to SQLite database in file
$file_db = new PDO('sqlite:frp.sqlite');
$file_db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = 'SELECT * from frp_teamdata';
$stmt = $file_db->prepare($sql);
$stmt->execute();
$sqliteresults = $stmt->fetch(PDO::FETCH_ASSOC);
//Prepare the statement only once!
$stmtmysql = $pdomysql ->prepare("INSERT INTO frp_teamdata (name, value) VALUES (:name, :value)");
//Bind the params only once -- I assume the keys and values are strings
$stmtmysql->bindParam(':name', $key, PDO::PARAM_STR);
$stmtmysql->bindParam(':value', $value, PDO::PARAM_STR);
foreach($sqliteresults as $results){
foreach($results as $key => $value){
$stmtmysql->execute();
}
}
}
catch (PDOException $e) {
print 'Exception : ' . $e->getMessage();
}
?>
Note: I have not tried the code, so let me know if you have any issues.
