How can differences in character sets between MySQL servers impact the export and import of data in PHP?

Differences in character sets between MySQL servers can impact the export and import of data in PHP by causing encoding issues and data corruption. To solve this problem, you can set the character set for the connection, export, and import operations to ensure consistent encoding. 

// Set character set for connection
$mysqli = new mysqli("localhost", "username", "password", "database");
$mysqli->set_charset("utf8");

// Export data with correct character set
$result = $mysqli->query("SELECT * FROM table");
$data = array();
while ($row = $result->fetch_assoc()) {
    $data[] = $row;
}

// Import data with correct character set
foreach ($data as $row) {
    $mysqli->query("INSERT INTO table (column1, column2) VALUES ('" . $mysqli->real_escape_string($row['column1']) . "', '" . $mysqli->real_escape_string($row['column2']) . "')");
}
