What are the potential pitfalls of missing brackets or parentheses in PHP code?

Missing brackets or parentheses in PHP code can lead to syntax errors and cause the code to not run as expected. To fix this issue, it is important to carefully check the code for any missing brackets or parentheses and ensure that they are properly matched.

// Incorrect code with missing parentheses
if ($condition {
    // Code block
}

// Corrected code with proper parentheses
if ($condition) {
    // Code block
}
