Question

Overflow社区首次发帖！

目前我正在开发一个项目，并已开始使用PHP来动态插入页面。

此时此刻我已经......

switch ($route) {
  case 'step1':
        include('./views/enrolment/mainstream/_step1.php');
        include('./views/partials/_footer.php') ;
        break;
    case 'step2':
        include('./views/enrolment/mainstream/_step2.php');
        include('./views/partials/_footer.php') ;
        break;
    case 'step3':
        include('./views/enrolment/mainstream/_step3.php');
        include('./views/partials/_footer.php');
        break;
    case 'step4':
        include('./views/enrolment/mainstream/_step4.php');
        include('./views/partials/_footer.php');
        break;
    case 'step5':
        include('./views/enrolment/mainstream/_step5.php');
        include('./views/partials/_footer.php');
        break;
    case 'step6':
        include('./views/enrolment/mainstream/_step6.php');
        include('./views/partials/_footer.php');
        break;
    case 'step7':
        include('./views/enrolment/mainstream/_step7.php');
        include('./views/partials/_footer.php');
        break;

这意味着看起来非常长并且通过for循环更好地实现，但是我是PHP的新手并且完全不确定我将如何实现这个想法。

我们也欢迎任何其他没有使用for循环的建议！
谢谢你们！

Answer 1

您可以使用php的file_exists（）fn

检查该文件是否存在

if(file_exists('./views/enrolment/mainstream/_'.$routes.'.php')) {
    include('./views/enrolment/mainstream/_'.$routes.'.php');
    include('./views/partials/_footer.php') ;
}

处理其他部分以满足您的需要。

Answer 2

也许这个简单的解决方案对你有好处：

include('./views/enrolment/mainstream/_'.$route.'.php');
include('./views/partials/_footer.php');

Answer 3

大幅减少代码：

include('./views/enrolment/mainstream/_step' . $route . '.php');
include('./views/partials/_footer.php');

Answer 4

为什么不使用$route作为加载文件的变量？

include("./views/enrolment/mainstream/_{$route}.php");
include('./views/partials/_footer.php') ;

Answer 5

就像@praveen所说：

include('./views/enrolment/mainstream/_'.$routes.'.php');

但是你要重复：

include('./views/partials/_footer.php');

对于每个查询，为什么不在页面中将其作为静态？

Answer 6

最好检查$route值

if (in_array($route, range(1, 7))){
    include('./views/enrolment/mainstream/_'.$route.'.php');
    include('./views/partials/_footer.php') ;
} else {
    //...error code
}

Answer 7

怎么样

$i = 1;
$steps = 7;

for($i = 1; $i <= $steps; $i++) {
  if($route === 'step' . $i) {
     include('./views/enrolment/mainstream/_step' . $i . '.php');
     include('./views/partials/_footer.php');
     break;
  }
}

Answer 8

for($i = 0; $i < 7; $i++){
    if($route == "step" . $i){
        include('./views/enrolment/mainstream/_step' .$i . '.php');
        include('./views/partials/_footer.php');
        break;
    }
}
