Re: bad use of foreach() when building xml str from xml tree(source code provided here).

["Scott Fletcher" <scott@xxxxxxxxx>]

Here's we go.  A better script here.  Now I only need to figure out how to
add data to the string and assigned it to string 1 when done.  I used hte
break command there to make a point here.  Maybe this will work...

$array = array
(
  'NEWSFEED' => array
  (
    '0' => array
    (
      'MESSAGE' => array
      (
        '0' => array
        (
          'COMMENT' => array
          (
            '0' => array
            (
              'VALUE' => 'Comment #1'
            )
          )
        ),
        '1' => array
        (
          'COMMENT' => array
          (
            '0' => array
            (
              'VALUE' => 'Comment #2'
            )
          )
        )
      )
    )
  )
);

  function GetXmlStr($tree)
  {
     $branch_level = 0;  //Tree's branches level...

     XmlTreeDecompile($tree, $branch_level, $str1, $str2, $str3);
//echo $str1." #<br>";
//echo $str2." #<br>";
//echo $str3." #<br>";

     return htmlentities($str1.$str2.$str3);
  }
  function XmlTreeDecompile($tree, $branch_level, &$str1, &$str2, &$str3)
  {
     $branch_level++;

     foreach($tree as $key => $value)
     {
        if ($branch_level % 2 != 0) {  //xml name-tag counter...
           if(!(is_array($value))) {
              $str2 .= str_repeat("
",$branch_level)."<".$key.">".$value."</".$key.">"."\r\n";
           } else {
              $str1 .= str_repeat(" ",$branch_level)."<".$key.">"."\r\n";
              XmlTreeDecompile($value, $branch_level, $str1, $str2, $str3);
              $str3 .= str_repeat(" ",$branch_level)."</".$key.">"."\r\n";
           }
        } else {  //Xml tag's name...
           //echo $key." #<br>";
           if ($key != 0) {
              break;
              //$str1 .= $str2;
              //$str2 = "";
           }
           XmlTreeDecompile($value, $branch_level, $str1, $str2, $str3);
        }
     }
     echo $str1." \n--\n";
     echo $str2." \n--\n";
     echo $str3." \n--\n";
  }

  $xml_string = GetXmlStr($array);

  echo "\n<br><br>\n".$xml_string;
