What is the significance of using var_dump() instead of echo for displaying variable values in PHP code?

When displaying variable values in PHP code, using var_dump() instead of echo provides more detailed information about the variable, including its data type and structure. This can be especially helpful when debugging code or trying to understand the contents of complex variables such as arrays or objects. var_dump() is a versatile function that can handle a wide range of data types, making it a valuable tool for developers.

$variable = "Hello, World!";
var_dump($variable);
