How can PHP developers effectively debug issues related to variable values?

To effectively debug issues related to variable values in PHP, developers can use functions like var_dump() or print_r() to print out the variable values and data types. This can help identify any unexpected values or inconsistencies in the variables. Additionally, using error reporting functions like error_reporting(E_ALL) can help catch any notices or warnings related to variable values. 

// Example code snippet to debug variable values
$variable1 = "Hello";
$variable2 = 123;
$variable3 = ['apple', 'banana', 'cherry'];

var_dump($variable1);
print_r($variable2);
var_dump($variable3);

error_reporting(E_ALL);
