What are common pitfalls when using PHP to execute MySQL queries stored in a file?

One common pitfall when using PHP to execute MySQL queries stored in a file is not properly handling errors or exceptions that may occur during the query execution. To solve this issue, you should implement error handling to catch and handle any potential errors that may arise. 

<?php

// Connect to MySQL database
$connection = mysqli_connect("localhost", "username", "password", "database");

// Check connection
if (!$connection) {
    die("Connection failed: " . mysqli_connect_error());
}

// Read SQL queries from a file
$sqlQueries = file_get_contents("queries.sql");

// Execute SQL queries
if (mysqli_multi_query($connection, $sqlQueries)) {
    do {
        // Check if there are more results
        if ($result = mysqli_store_result($connection)) {
            mysqli_free_result($result);
        }
    } while (mysqli_next_result($connection));
} else {
    echo "Error executing queries: " . mysqli_error($connection);
}

// Close connection
mysqli_close($connection);

?>
