PHP：如果/ elseif / else语句不正确更好的方法？ [关闭]

Question

How do make this if statement work for 0, 1 and 2 cats?

When $cats = 0 or 1 it echos "It is fine you only have 2 cats"

Any code suggestions?

 <?php
        //If you have more then 2 cats it is illegal
        //if you have 20 or more cats "you are a freak!"
        //If you have 2 cats "It is fine you only have 2 cats".
        //If you have 1 cats "It is fine you only have 1 cat".
        //If you have 0 cats "You don't have any cats no problem".
        $cats = 25;
        if ($cats > 2 && $cats < 20){
            echo "You have too many cats, it is illegal!";
        } elseif ($cats >= 20) {
            echo "you are a freak!";
        } elseif ($cats = 2) {
            echo "It is fine you only have 2 cats";
        } elseif ($cats = 1) {
            echo "It is fine you only have 1 cat";
        } elseif ($cats = 0){
            echo "You don't have any cats no problem";
        }
    ?>

Answer 1

Use == for comparison, = is for assignment.

Additionally, consider rearranging your code to this:

switch($cats) {
case 0:
    echo "You don't have any cats";
    break;
case 1:
    echo "You have 1 cat";
    break;
case 2:
    echo "You have 2 cats";
    break;
default:
    if( $cats < 20) echo "You have too many cats";
    else echo "You are a freak!";
}
