您不能像这样比较数字。请参阅下面的更正代码。

<?php
        $randinterger = rand(10,100));

if ($randinterger <= 25) {
    echo ($randinterger);
    echo ("This is less that 25");
} elseif (26 < $randinterger && $randinterger <= 50) {
    echo ($randinterger);
    echo ("This is between 25 and 50");
} elseif (50 < $randinterger && $randinterger <= 75) {
    echo ($randinterger);
    echo ("This is between 50 and 75");
} else (75 < $randinterger && $randinterger <= 100) {
    echo ($randinterger);
    echo ("This is between 75 and 100");
}

    ?>

您必须拆分条件。您想知道randinteger是否小于x AND 大于Y。
