How can the error "Only variables should be passed by reference" be resolved in PHP code, specifically when using func_get_args()?

When using func_get_args() in PHP, the error "Only variables should be passed by reference" can occur if the result of func_get_args() is used directly as a reference parameter. To resolve this error, assign the result of func_get_args() to a variable and then pass that variable as a reference parameter. 

function exampleFunction(&$args) {
    $args = func_get_args();
    // Rest of the function code
}

// Call the function
exampleFunction(...$args);
