I am getting an error message saying that my
tags are empty even though the result pane is showing the proper echo. I have tried resetting the code and refreshing my browser page and I still get the same error message. Here is my code in case I am doing something wrong.<?php
// Your code here
class Cat {
public $isAlive = true;
public $numLegs = 4;
public $name;
public function __construct($name){
$this->name = $name;
}
public function meow() {
return "<p>Meow meow</p>";
}
}
$cat1 = new Cat("CodeCat");
echo $cat1->meow();
?>
Answer 5378624f9c4e9de9f20035af
When the PHP code is like this:
<p>
<?php
echo "Personal Homepage: Hypertext Processor";
?>
</p>
Whatever is echoed comes directly inside of the <p> tags. So, the above code would, on executing, produce:
<p>Personal Homepage: Hypertext Processor</p>
To test, apply a CSS rule, say color:blue; on p element, and notice the text that PHP echoed is blue!
Now, note that the <?php ?> tags for this exercise are already inside of p tags. So, whatever you echo, say "Meow meow!", would come directly inside of the p tag, and the exercise would pass you.
But by adding an extra <p>, and outputting like echo "<p>Meow meow</p>", it would confuse the code checker and it would throw an error.
Thus, simply, don’t use the <p> tags in output strings.
Hope that clarifies your doubt!

Not really adding an answer to my own question, but rather adding more of my confusion. I removed the
tags from the meow() method and now the code passes. I thought that the tags were supposed to be there. Other lessons worked with the tags in. Don’t these tags allow multiple echos to display on separate lines rather than in a row on the same line?Answer 53777637631fe9ef9d001715
Got the same error on 10/10 with this code:
<?php /*Your code here */
echo "<p>Now I know the basics of OOP!</p>";
?>
Again, removed the tags and it passed. I guess I am just too over zealous with the paragraph tags. So… my question now is “When should
tags be used in a function’s return and when should they not be used?”1 comments
Tim Bouscal over 9 yearsthe issue isn’t your tags. The issue is that the confirmation tests are VERY specific. If your final HTML doesn’t look the way it expects you will fail.

mustardnose over 9 yearsyou need to change the call to the method: echo $cat1 -> cat(); to echo $cat1 -> meow();
Валентин Георгиев over 9 yearsCorrect syntax is : $cat1 = new Cat(“CodeCat”);
echo $cat1->meow();

Answer 5395e64f80ff332d45000540
I think your code at this level:
$cat1 = new Cat("CodeCat");
Is wrong. The $cat1 is not defined to which property it belongs in the Cat class. It should look like this:
$cat1 = new Cat($name = "CodeCat");
This sends the new “CodeCat” to the name property.

mikedegrande almost 10 yearsWouldn’t your constructor direct it to the proper property?
Zuo Bruno Foy almost 10 years@mikedegrande its good you try my suggestion, if it works learn from what I said, if not please post error in your reply. And NO. Computers do not “Think” they do as they are told and in this case you have not explained what it should do properly. So the computer is a bit confused.
