Hello, I’m wanting to understand a part of PHP documentation and I’m not getting it. I want to understand the part that speaks of comparison with various types.
See more on this link: https://secure.php.net/manual/en/language.operators.comparison.php in part comparison with various types, i do not understand the examples, could give examples with code written in php of how what is written in the documentation is done (based on the documentation)?
I did so in IDEONE of the first example and the result was not as written in the documentation.
Example:
<?php
$palavra = NULL;
$palavra2 = "Pão";
if($r = $palavra == $palavra2) {
var_dump($r);
} else {
var_dump($r);
}
?>
It wasn’t the result that the documentation says, could you give examples of some of those models for me to understand.
I wanted to understand these PHP documentations. I use PHP 7 and I’m starting in the PHP world, but I’ve known PHP for a long time, but now I’m starting programming in it.
To say I don’t understand is very complicated, try to be more specific. The way you are each will give a different answer and can be no use because no one knows what your question is. At the moment there is a description of your situation, not a doubt, we need doubts to help.

I want real example of what is discussed in the comparison section with various types, I did not understand how to do that in the code.

What was the result and what was the expected result?

the result was FALSE, the expected result is what it says in the PHP documentation: "Converts NULL to "", numeric or lexical comparison" and I didn’t understand this and the result wasn’t even what the documentation says
