php - 在以下示例中，如何使用PHP foreach？(How can I use PHP foreach in the following example?)

Question

I have a big issue right now in using php foreach function.

(我现在在使用php foreach函数时遇到了一个大问题。)

I need to return each name plus each value from the html source code below or a similar one.

(我需要从下面的html源代码或类似的源代码中返回每个名称加上每个值。)

Example: {_pn_Brand:Dell}.

(示例：{_ pn_Brand：Dell}。)

Everything good so far.

(到目前为止一切都很好。)

My problem is that the source code contains one or more parameters (in my example below: _pn_Hardware Connectivity, _pn_Features) which can be found several times in the source code and I only need to return the checked ones.

(我的问题是源代码包含一个或多个参数（在下面的示例中为_pn_Hardware Connectivity和_pn_Features），这些参数可以在源代码中多次找到，而我只需要返回选中的参数即可。)

To be more specific I need to return something like: {_pn_Hardware Connectivity:HDMI,USB 2.0}, {_pn_Features:Backlit Keyboard,Bluetooth,Built-in Microphone,Built-in Webcam}.

(具体来说，我需要返回以下内容：{_pn_Hardware Connectivity：HDMI，USB 2.0}，{_ pn_Features：Backlight Keyboard，Bluetooth，内置麦克风，内置摄像头}。)

Please keep in mind that the attributes names like _pn_Hardware Connectivity or _pn_Features can change in other source codes so I need a foreach function to generally solve my problem.

(请记住，诸如_pn_Hardware Connectivity或_pn_Features之类的属性名称可以在其他源代码中更改，因此我需要一个foreach函数来普遍解决我的问题。)

I hope you guys understand exactly what I'm looking for.

(我希望你们能完全理解我在寻找什么。)

My apologise for the poor explanation but couldn't think of a better one for the moment.

(对于抱歉的解释，我深表歉意，但暂时无法想到更好的解释。)

Please check the html source code below:

Answer 1

I will advise you to first group the input in two groups: Input group and Checkbox group Then you can create variables and loop to display the inputs:

(我建议您首先将输入分为两组：输入组和复选框组然后可以创建变量并循环显示输入：)

 <php $inputGroup = [ ['_pn_Brand', 21, 50, 'Brand', 'Dell'], ['_pn_MPN', 21, 50, '', ''], ... ]; $checkboxGroup = [ ['_pn_Hardware Connextivity', [ 'DisplayPort', 'Mini DisplayPort', ... ]], ['_pn_Features', [ '10/100 LAN Card', '3D Camera', ... ]] ]; // Then you loop each varaible to display the inputs foreach($inputGroup as $input) { echo '<input type="text" name="'. $input[0] .'" size="'. $input[1] .'" maxlength="'. $input[2] .'" gname="'. $input[3] .'" value="'. $input[4] .'">'; } foreach($checkboxGroup as $checkbox) { foreach($checkbox[1] as $value) { echo '<input type="checkbox" name="'. $checkbox[0] .'" value="'. $value .'">' } } ?>
