How to use foreach with PHP & XML (simplexml)

Question

Anyone that knows PHP and XML out there? Then please have a look!

This is my PHP code:

Answer 1

<? foreach($movie->regions->region->categories->categorie as $category) { ?>
<p>Categori: <?= $category ?></p>
<? } ?>

Answer 2

function categoryList(SimpleXmlElement $categories){
  $cats = array();
  foreach($categories as $category){
    $cats[] = (string) $category;
  }

  return implode(', ', $cats);

}

Then you can jsut call it from your loop like:

<? echo categoryList($movie->regions->region->categories); ?>

Using an array and implode removes the need for logic of counting and detecting the last category.

Isolating it in a function makes it easier to maintain and is less confusing than nesting the loop (though admittedly nested loops arent that confusing).

Answer 3

this is how you use foreach with an simplexmlElement:

$xml = simplexml_load_file("movies.xml");
foreach ($xml->children() as $children) {
    echo $children->name;
}

Answer 4

Try this.

<?php
$xml = simplexml_load_file("movies.xml");
foreach ($xml->movie as $movie) {

    echo '<h2>' . $movie->title . '</h2>';
    echo '<p>' . $movie->year . '</p>';

    $categories = $movie->regions->region->categories->categorie;

    while ($categorie = current($categories)) {
        echo $categorie;
        echo next($categories) ? ', ' : null;
    }

    echo '<p>' . $movie->countries->country . '</p>';
}
?>

Answer 5

<?php
$cat_out='';
foreach($movie->regions->region->categories->categorie as $cat){
 $cat_out.= $cat.',';
}
echo rtrim($cat_out,',');
?>

Answer 6

You need to iterate through the categorie elements too, in the same way you've iterated through movies.

echo '<p>';
foreach($movie->regions->region->categories->categorie as $categorie){
    echo $categorie . ', ';
}
echo '</p>';

You'll probably want to trim the trailing , as well.

The method mentioned in my comment:

$categories = $movie->regions->region->categories->categorie;
while($category = current($categories)){
    echo $category . next($categories) ? ', ' : '';
}
