使用数组动态生成 switch 语句的 case
我正在创建一个脚本来自动为我的网站的各个部分生成 RSS 提要。我已通过数据库进行查询，并有一个数据数组，代表名为 $showData 的每个部分。我使用 switch 语句根据网站的部分设置各种变量。我希望 switch 语句中的 case 是动态的，而不是每次添加节目时都必须更改此脚本。
<?php
switch($section){
case 'show1':
$title = $showData['show1'] . ' Title';
$description = $showData['show1'] . ' Description';
break;
case 'show2':
$title = $showData['show2'] . ' Title';
$description = $showData['show2'] . ' Description';
break;
}
?>
我尝试使用 foreach 循环来创建每个案例，但您不能将其放入 switch 语句中。我在另一篇文章中读到的其他人建议使用eval()。
这是我尝试过的代码，但不起作用。
<?php
switch($showFilter)}
foreach($showFilters as $key => $value){
case $key:
$title = $value;
$description = $value;
break;
}
}
?>
这是数组的 print_r
Array
(
[show1] => The Name of Show One
[show2] => The Name of Show Two
)
I'm creating a script to auto generate an RSS feed for the various sections of my website. I've queried by database and have an array of data which represents each section called $showData. I'm using a switch statement to setup various variables depending upon the section of the site. Instead of having to change this script each time I add a show, I'd like the case in my switch statement to be dynamic.
<?php
switch($section){
case 'show1':
$title = $showData['show1'] . ' Title';
$description = $showData['show1'] . ' Description';
break;
case 'show2':
$title = $showData['show2'] . ' Title';
$description = $showData['show2'] . ' Description';
break;
}
?>
I attempted to use a foreach loop to create each case, but you can't put that inside a switch statement. Someone else in another post I read suggested using eval().
Here's my code that I tried, that doesn't work.
<?php
switch($showFilter)}
foreach($showFilters as $key => $value){
case $key:
$title = $value;
$description = $value;
break;
}
}
?>
Here's a print_r of the array
Array
(
[show1] => The Name of Show One
[show2] => The Name of Show Two
)

除了使用
switch块，您是否可以尝试：Instead of using a
switchblock, could you not just try:
