How can one effectively debug PHP code when encountering issues with variable values?

When encountering issues with variable values in PHP code, one effective way to debug is by using the "var_dump()" function to display the contents of the variable and its data type. This can help identify any unexpected values or inconsistencies. Additionally, using "echo" or "print_r()" can also be helpful in printing out variable values for troubleshooting. 

// Example code snippet to debug variable values using var_dump()
$variable = "Hello World";
var_dump($variable);
