What are some common debugging techniques for accessing variable names in PHP?

When debugging PHP code, it can be helpful to access the variable names to understand their values and pinpoint any issues. One common technique is to use the var_dump() function, which displays structured information about variables, including their names. By using var_dump(), you can easily see the variable names and their corresponding values for debugging purposes. 

// Example of using var_dump() to access variable names
$variable1 = "Hello";
$variable2 = 123;

var_dump(compact('variable1', 'variable2'));
