How can debugging techniques like var_dump() help in identifying errors related to non-object variables in PHP?

When dealing with non-object variables in PHP, errors can occur when trying to access object properties or methods on non-object variables. To identify and debug these errors, you can use the var_dump() function to inspect the variable type and value at runtime. By using var_dump() on the variable in question, you can quickly determine if it is an object or not, helping you troubleshoot and fix any issues related to non-object variables.

$variable = "Hello World";

var_dump($variable);
