只要输入为“女性”且已婚，则不显示任何内容，但如果输入为“单身女性”，则会显示输出 - Nothing appears whenever the input is Female and married but there is an output if the input is Female an single

Nothing appears whenever the input is Female and married but there is an output if the input is Female an single

我是一个PHP程序员，需要帮助。

无论何时输入是Female和married，都不会出现任何内容，但如果输入是Female和single，则会出现输出。我很难弄清楚。

这是代码：

if($gender =="Female" And $status=="married"){      
    $output.= " <b>  Your Fullname: </b>  Mrs.  " .$fname.    "    "  .$mname.   "   " .$lname.   "</br>" ;
}
else{
    if($gender =="Female" And $status =="single"){      
        $output.= " <b>  Your Fullname: </b> Ms.  " .$fname.    "    "  .$mname.   "   " .$lname.   "</br>" ;
    } else{
        $output.= " <b>  Your Fullname: </b>  Mr. " .$fname.    "    "  .$mname.   "   " .$lname.   "</br>" ;
    }
}

我们需要知道$gender和$status的解析结果，才能真正知道你应该得到什么条件。

你可以把它浓缩成一个三元运算符。。。

$output.= " <b>  Your Fullname: </b>  ". $gender == 'Female' ? ($status == 'married' ? 'Mrs.' : 'Ms.') : 'Mr.' ."  " .$fname.    "    "  .$mname.   "   " .$lname.   "</br>" ;

或者对它们的名称进行预处理。。。

$prefix = 'Mr.';
if($gender == 'Female')
{
    if($status == 'married')
    {
        $prefix = 'Mrs.';
    }
    else
    {
        $prefix = 'Ms.';
    }
}
$output.= " <b>  Your Fullname: </b>  " .$prefix. "  " .$fname.    "    "  .$mname.   "   " .$lname.   "</br>" ;

虽然and在技术上可以充当&&，但您可能需要遵守惯例。&&将是最常见的语法。我最初的怀疑是，$status实际上从未=="已婚"。
