How does PHP handle references compared to other programming languages, and what are the implications for coding practices?

PHP handles references differently compared to other programming languages by using the "&" symbol to create a reference to a variable. This allows multiple variables to point to the same data in memory, making it possible to modify the original value through any of the references. When working with references in PHP, it's important to be mindful of unintended side effects and ensure proper handling to avoid unexpected behavior in your code. 

// Using references in PHP
$a = 5;
$b = &$a; // $b is now a reference to $a
$b = 10; // $a is now also 10
echo $a; // Output: 10
