Question

我有这个XML：

$s = $this->input->post('name');
return print_r($s);

我需要有关如何将数据（从标签PARAM中）获取到字段中的建议：

$ array [0] [聚酯] = 96％； $ array [1] [elastan] = 4％;

Answer 1

<?php
$xmlstr = "<DATASET>
<ITEM>
<NAME>name product</NAME>
<SELL>0</SELL>
<PARAM>
<PARAM_NAME>material</PARAM_NAME>
<VAL>polyester</VAL>
<PERCENTAGE>96%</PERCENTAGE>
</PARAM>
<PARAM>
<PARAM_NAME>material</PARAM_NAME>
<VAL>elastan</VAL>
<PERCENTAGE>4%</PERCENTAGE>
</PARAM>
</ITEM>
</DATASET>";
   $xml_reader = new XMLReader();
   $xml_reader->xml($xmlstr);

   while ($xml_reader->read() && $xml_reader->name != 'PARAM');
   $array = [];
   $i = 0;
   while ($xml_reader->name == 'PARAM') {
     // load the current xml element into simplexml
     $param = new SimpleXMLElement($xml_reader->readOuterXML());

     // now you can use your simpleXML object ($xml)
     $array[$i] = array( (string)$param->VAL => (string)$param->PERCENTAGE );

     // move the pointer to the next param
     $xml_reader->next('PARAM');
     $i++;
   }

   // don’t forget to close the file
   $xml_reader->close();

   print_r($array);
?>

结果：

Array
(
    [0] => Array
        (
            [polyester] => 96%
        )

    [1] => Array
        (
            [elastan] => 4%
        )

)
