How does PHP support the use of references in comparison to other programming languages?

PHP supports the use of references by allowing variables to be assigned by reference using the `&` symbol. This means that when a variable is assigned by reference, any changes made to the variable will also affect the original variable it references. This can be useful when passing variables by reference to functions or when working with large data structures to avoid unnecessary copying. 

// Example of using references in PHP
$value = 5;
$reference = &$value;

$reference = 10;

echo $value; // Output will be 10
