在PHP中将相同的键推送到关联数组

Question

I'm trying to add arrays to an associative array in PHP. I know this isn't how you're supposed to use the keys but I'm parsing the array to XML which needs te same <line> tag.

Desired array:

array(
    'line' => array(
        // Ean-artikelcode
        'Article_Eancode' => 8710624618216,
        // Leveranciersartikelcode
        'Article_Supplier_Partno' => 22304
    ),

    'line' => array(
        'Article_Eancode' => 8710622648216,
        'Article_Supplier_Partno' => 22304
    )
);

Which I am trying to get with this code:

$artikelenFormatted = array();
$artikelen          = array(
    'a',
    'b',
    'c'
);
foreach ($artikelen as $art) {
    $artikelenFormatted['line'] = array(
        "Article_Eancode" => "a",
        "Article_Supplier_Partno" => "b"
    );
}

Which produces:

array (size=1)
  'line' => 
    array (size=2)
      'Article_Eancode' => string 'a' (length=1)
      'Article_Supplier_Partno' => string 'b' (length=1)

Because $array['line'] keeps getting overwritten so there aren't multiple entries

How would I do this?

EDIT: Sample of the desired XML

<Lines>
  <Line>
    <Article_Eancode>87XXXXXXXXXXX</Article_Eancode>
    <Article_Supplier_Partno>22304</Article_Supplier_Partno>
  </Line>
  <Line>
    <Article_Eancode>87XXXXXXXXXXX</Article_Eancode>
    <Article_Supplier_Partno>22303</Article_Supplier_Partno>
  </Line>
  <Line>
    <Article_Eancode>87XXXXXXXXXXX</Article_Eancode>
    <Article_Supplier_Partno>22324</Article_Supplier_Partno>
  </Line>
  <Line>
    <Article_Eancode>87XXXXXXXXXXX</Article_Eancode>
    <Article_Supplier_Partno>22305</Article_Supplier_Partno>
  </Line>
  <Line>
    <Article_Eancode>87XXXXXXXXXXX</Article_Eancode>
    <Article_Supplier_Partno>22323</Article_Supplier_Partno>
  </Line>
</Lines>

Answer 1

An array cannot have two (or more) of the same key. Consider; what would $array['line'] return?

What you're looking for is:

foreach ($artikelen as $art) {
    $artikelenFormatted['line'][] = array(
        "Article_Eancode" => "a",
        "Article_Supplier_Partno" => "b"
    );
}

Notice the [] after ['line']. This will make $artikelenFormatted['line'] an array where each element is an array of the data.

Edit:

To get it to work with XML, use the following:

foreach ($artikelen as $art) {
    $artikelenFormatted[]['line'] = array(
        "Article_Eancode" => "a",
        "Article_Supplier_Partno" => "b"
    );
}

And amend the array_to_xml function you reference to:

function new_array_to_xml( $data, &$xml_data ) {
    foreach( $data as $key => $value ) {
        if( is_array($value) ) {
            if( is_numeric($key) ){
            array_to_xml($value, $xml_data);
            }
            else
            {
            $subnode = $xml_data->addChild($key);
            array_to_xml($value, $subnode);
            }
        } else {
            $xml_data->addChild("$key",htmlspecialchars("$value"));
        }
     }
}
