Questions about Return in Function

[doubledee]

Some questions about the return statement in a Function...

 

1.) Do you have to assign what is being returned to a variable, before you can use the return statement.

 

For example, must you do this...

$postsPerDay = round(($numberOfPosts/$daysAsMember), 3);

return $postsPerDay;

 

 

Or is it acceptable to do this...

return round(($numberOfPosts/$daysAsMember), 3);

 

 

2.) Can you have return in multiple places in your Function?

 

For example, can you do this...

if ($estimatedAge < 20){
	return 'Youth';
}else if ($estimatedAge < 30){
	return '20-something';
}else if ($estimatedAge < 40){
	return '30-something';
}else{
	return 'Senior';
}

 

 

Or do you have to do this...

if ($estimatedAge < 20){
	$ageRange = 'Youth';
}else if ($estimatedAge < 30){
	$ageRange = '20-something';
}else if ($estimatedAge < 40){
	$ageRange = '30-something';
}else{
	$ageRange = 'Senior';
}

return $ageRange;

 

Thanks,

1) No, you do not have to store the value in a variable before retuning it.

2) Yes, just be aware that return exits the function

On the second question... i think the second way you did that is the better way to do. i think it improve the reading and the sense of the code.
