Why don’t these run the same? The first is my answer to the exercise, the second is the official solution. I don’t see any reason why they wouldn’t work the same way. Can anybody help?

echo “Hello, there. What’s your first name?\n”;
$first_name = readline(">> “);
if (strlen(first_name) > 8) { echo "Hi, {first_name}. That’s a long name.”;
} elseif (strlen(first_name) > 3) { echo "Hi, {first_name}.";
} else {
“Hi, ${first_name}. That’s a short name.”;

__________ Official Solution __________________

echo “Hello, there. What’s your first name?\n”;

$name = readline(">> ");

$name_length = strlen($name);

if (name_length > 8) { echo "Hi, {name}. That’s a long name.";
} elseif (name_length > 3) { echo "Hi, {name}.";
} else {
echo “Hi, ${name}. That’s a short name.”;

They would produce the same result. Both are correct.

Except for the missing $ here and there.

Do you remember the error message that you received?

Edit : found it.

I copy/pasted your code.

On the first line : $first_name = readline(">> “);

The second double-quote is what’s causing the problem. Now I’m not sure how you got that. But that double-quote needs to look like the first one.

Edit 2 :

Nope. Not just on that first line actually.

Here as well : "Hi, {first_name}. That’s a long name.”;

And here : “Hi, ${first_name}. That’s a short name.”;

How weird! Not sure how that happened at all. Thanks for your help!
