Why is using echo for debugging in PHP considered inadequate, as mentioned in the forum thread?

Using echo for debugging in PHP is considered inadequate because it can be cumbersome to insert echo statements throughout the code, especially in larger projects. Additionally, echoing variables or messages can disrupt the flow of the output, making it harder to read and understand the debugging information. A better approach is to use PHP's built-in debugging functions like var_dump() or print_r() to display the contents of variables or arrays in a more structured and readable format. 

// Example of using var_dump() for debugging
$variable = "Hello, World!";
var_dump($variable);
