What are the potential issues with combining echo/print and return statements in PHP functions?

Combining echo/print and return statements in PHP functions can lead to unexpected behavior or errors, as they both output data but in different ways. To solve this issue, it's best to separate the output logic from the return logic. You can store the output in a variable and then return that variable at the end of the function. 

function exampleFunction() {
    $output = "Hello, World!";
    echo $output;
    
    return $output;
}
