Question

I have an XPath query that gets Genres of a movie.

$genreXpath = $xml_data->xpath("//category");

I get the attributes from $genreXpath like this

$genreName=array();
$genresID=array();
$i=0;

foreach($genreXpath as $node) {
    $genre = $node->attributes();
    $genreName[$i] = $node["name"];
    $genresID[$i] = $node["id"];    

        $i++;
}

I’m going to be writing these values to a Db hence the two different arrays.
This code works but I know there has to be a better way of doing this be it with a 2 d array, not using a $i counter or something more obvious that I haven’t figured out….any pointers???

Answer 1

foreach($genreXpath as $i=>$node) {  //note $i is your index of the current $node
    $genre = $node->attributes();
    $genreName[$i] = $node["name"];
    $genresID[$i] = $node["id"];    
}

It auto increments and you do not need to declare it above.
