你怎么读这个php系列？ [关闭]

Question

I'm new to PHP and I really like the concept behind it. Would you be kind enough to explain to me how a line like this would be read?

if ($ThisOutput->result == "success")

In other words, what does that line above mean? How can I understand it?

Thanks!

Wow! Thank you to all who have answered! I totally understand this now! :-) I wish I could choose all three of you as the accepted answer, but I can only choose one. Good job ya'll!

Answer 1

In php, variables are denoted by a $ prefix. Therefore, $ThisOutput is a variable.

There are several types of variables. For variables of type stdClass (objects) their properties can be accesed with the -> operator.

Your code is evaluating if the property 'result' for the object $ThisOutput has a value equal to the string "success".

An if construct will execute a further command if the argument evaluates to true. So in this case, if $ThisOutput->result is "success" something will be executed, and it won't in any other case.
