How can PHP be used to execute queries from a large SQL file during a webpage transfer, and what considerations should be taken into account?

To execute queries from a large SQL file during a webpage transfer, you can use PHP to read the SQL file line by line and execute each query individually. This can help prevent memory issues that may arise from trying to execute the entire file at once. Additionally, using transactions can improve performance by grouping multiple queries together. 

<?php
// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Read SQL file line by line and execute queries
$sqlFile = 'large_file.sql';
$queries = file($sqlFile);
foreach ($queries as $query) {
    $conn->query($query);
}

// Close connection
$conn->close();
?>
