What are the best practices for validating and processing chess moves in a PHP application?

When validating and processing chess moves in a PHP application, it is important to implement a system that checks the validity of each move based on the rules of chess. This can include checking for legal piece movements, ensuring the move does not put the player's own king in check, and verifying that the move is within the boundaries of the board. One way to approach this is to create a function that takes in the current board state and the proposed move, and returns a boolean value indicating whether the move is valid.

function isValidMove($board, $move) {
    // Implement logic to validate the move based on chess rules
    // Check if the move is within the boundaries of the board
    // Check if the move is a legal piece movement
    // Check if the move puts the player's own king in check
    // Return true if the move is valid, false otherwise
}
