What do you mean, "PHP doesn't support unmarked wholes (integer)"?



  • ♪ http://php.net/manual/ru/language.types.integer.php specified:

    PHP does not support unmarked wholes (integer)

    What does that mean, unmarked wholes?


    I'm guessing, for example, 1 - unmarked; -1 or +1 - I know. But PHP is working adequately with all three options. ♪ ♪



  • This is not a correct wording. The correct one is: "PHP does not support unmarked data types."

    An unmarked whole type of data is a complete type of data that cannot store negative numbers.

    Typically, in statistically typified programming languages, the target data types are coupled. Okay, C++11 has a character type. int32_tin the number of -2 147 483 648 to 2,147,483 647 - and a ferry unknown type uint32_tthe number between 0 and 4 294 967 295.

    But in PHP,, as in a dynamic version, the whole type of data is only one (integer) and it's a sign.
