今天的PHP回声明天回应别的东西

Question

此代码不起作用.回声是空白的.PHP版本:PHP 5.0.5版

$today=(int)date("j");  # today
$statedate=12;
if ((int)$startdate == (int)$today){
    echo '12th';
}
if ((int)$startdate == (int)$today){
    echo '14th';
}

Answer 1

$today=(int)date("j");  # today
$statedate=12; //NEVER USED!
if ((int)$startdate == (int)$today){
    echo '12th';
}
if ((int)$startdate == (int)$today){
    echo '14th';
}

你是定义$statedate而不是 $startdate
