How can the error message "Only variable references should be returned by reference" be resolved in PHP code?

The error message "Only variable references should be returned by reference" occurs when a function tries to return a reference to a value that is not a variable. To resolve this issue, you should modify the function to return the value directly instead of returning it by reference. 

// Incorrect code that causes the error
function &getValue() {
    $value = 10;
    return $value;
}

// Corrected code without the error
function getValue() {
    $value = 10;
    return $value;
}
