PHP - What's going on here?
Hi.. Quite new to LAMPy stuff - I'm trying to pick apart a bit of code here. Can someone explain what's going on? I get what it's doing, I just can't put a name to the functionality to explore it further if that makes sense.
Obviously the ? and : is doing some decision making based on a true/false from the empty($error) - is this part of 'echo' or something else? Googling "PHP echo ? :" doesn't yield much of interest
cheers!
php > unset ($error);
php > echo (empty($error)) ? 'The string is empty' : 'The string has something in';
The string is empty
php > $error = "Something";
php > echo (empty($error)) ? 'The string is empty' : 'The string has something in';
The string has something in
php > Obviously the ? and : is doing some decision making based on a true/false from the empty($error) - is this part of 'echo' or something else? Googling "PHP echo ? :" doesn't yield much of interest

A friendly place for developers to meet other devs, ask questions, get help, and just have a good time 🙂.
