PHP foreach循环元素索引
我有一个XPath查询，可以获得电影的类型。
$genreXpath = $xml_data->xpath("//category");
$genreName=array();
$genresID=array();
$i=0;
foreach($genreXpath as $node) {
$genre = $node->attributes();
$genreName[$i] = $node["name"];
$genresID[$i] = $node["id"];
$i++;
}
没有找到相关结果

foreach($genreXpath as $key => $node) {贸会
$genres = array(); foreach($genreXpath as $node) { $genre = $node->attributes(); $genres[] = array($node["name"], $node["id"]); }
