What are some common challenges faced when manipulating and exporting data from one MySQL database to another using PHP?

One common challenge faced when manipulating and exporting data from one MySQL database to another using PHP is ensuring that the data types and structures of the tables in both databases match. This can lead to errors during data transfer if not handled properly. To solve this issue, it is important to carefully map the fields from the source database to the destination database and handle any necessary data type conversions. 

// Connect to the source database
$sourceConnection = new mysqli('source_host', 'source_username', 'source_password', 'source_database');

// Connect to the destination database
$destinationConnection = new mysqli('destination_host', 'destination_username', 'destination_password', 'destination_database');

// Select data from the source table
$sourceData = $sourceConnection->query('SELECT * FROM source_table');

// Loop through the source data and insert into the destination table
while ($row = $sourceData->fetch_assoc()) {
    // Manipulate data if needed
    // Map fields to match destination table structure
    $destinationConnection->query("INSERT INTO destination_table (field1, field2) VALUES ('".$row['source_field1']."', '".$row['source_field2']."')");
}

// Close connections
$sourceConnection->close();
$destinationConnection->close();
