How can locking problems in a database table affect the parallel execution of PHP scripts?

Locking problems in a database table can affect the parallel execution of PHP scripts by causing delays or conflicts when multiple scripts try to access or modify the same data simultaneously. To solve this issue, you can implement a locking mechanism in your PHP scripts to ensure that only one script can access the database table at a time, preventing conflicts and ensuring data integrity. 

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

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

// Lock the table
$conn->query("LOCK TABLES table_name WRITE");

// Perform database operations here

// Unlock the table
$conn->query("UNLOCK TABLES");

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