What are the potential pitfalls of using deprecated features like call-time pass-by-reference in PHP, as highlighted in the forum conversation?

Using deprecated features like call-time pass-by-reference in PHP can lead to compatibility issues with newer versions of PHP, as these features may be removed in future releases. It is recommended to update your code to use the appropriate syntax, such as passing variables by reference when defining the function instead of during the function call. 

// Before
function foo(&$var) {
    // function implementation
}

$bar = 'test';
foo(&$bar);

// After
function foo($var) {
    // function implementation
}

$bar = 'test';
foo($bar);
