What is the best and how to use it?
I'm trying to run this code for example and it does not work
if(1 !== 1 || 2) {
echo true;
}
It displays true being that it was only to show if X (in case 1) was indifferent to 1 or 2.

The if can be translated as se 1 não é identico a 1 OU dois(que é true) , while changing the values of the logical values, SE(falso OU verdadeira) ENTAO ... .
The first part of the sentence ( 1!==1 ) is false and the second (only 2 ) is considered true for php, since the language works with automatic casts, it defines a series of values that can be evaluated as false and anything outside it is true , as the sentences are connected through || (logical OR) a true value to validate the condtion is sufficient.
The difference between || and OR is that OR has less priority or in this case be wise for unexpected results or to add parentheses in the condition.
