How can missing arguments in function declarations lead to errors in PHP code?

Missing arguments in function declarations can lead to errors in PHP code because when a function is called with fewer arguments than expected, PHP will throw an error. To solve this issue, you need to make sure that all required arguments are provided when calling the function. 

// Function declaration with required arguments
function greet($name) {
    echo "Hello, $name!";
}

// Calling the function with the required argument
greet("John");
