Question

嗨，我有一个这样的txt文件：

lenovo,pc,mouse
mac,pc,mouse
dell,pc,mouse

，我想创建一个txt文件字符串（pc名称）第一部分的下拉列表。这是我的代码，但是我不想要它。它不会爆炸。有什么帮助吗？

echo "Which pc are you using?? <br>";   
$pc = file('pc.txt');
$name = ' ';
$name.="<option>Choose please</option>";
foreach ($pc as $type) { 
    $name .= '<option value="'.$type.'">'.$type.'</option>';
explode(',',$name);}
$select = '<select name="pc">'.$name.'</select>';
echo $select;

Answer 1

您必须爆炸$ type

echo "Which pc are you using?? <br>";   
$pc = file('pc.txt');
$name = ' ';
$name.="<option>Choose please</option>";
foreach ($pc as $type) { 
    $pc_name = explode(',',$type);
    $name .= '<option value="'.$pc_name[0].'">'.$pc_name[0].'</option>';
    // explode(',',$name);
}
$select = '<select name="pc">'.$name.'</select>';
echo $select;

Answer 2

从创建选项的循环内部的文件中断开行。

asset ProductionRecord identified by productionId{
    o String productionId
    o ProductionDetails productionDetails
    --> Order order 
    --> Manufacturer factory
}

asset Order identified by orderId {
  o String orderId
  o GarmentDetails garmentDetails
  o OrderStatus orderStatus
  --> Customer orderer
}

如何从txt文件获取列表并将其在PHP中爆炸？
