Fix Php > 7.0.1

[jadark]

Good morning,

I am currently working with your SDK in a version 7.1 of php and I have found a problem with a variable declaration in the file "simplexml.class.php", in the function "xml_load_file", where $ this-> result = ''; it must be $ this-> result = array ();

Thank you

Hello @jadark,

This issue was resolve with follow modifications in simplexml.class.php:

1. Change initialization for var $evalCode = '' to var $evalCode = array()

2. Add at the end in the function xml_reorganize the follow line $this->result = array('@attributes' => array()); before eval($this->evalCode);

The final function is:

    function xml_reorganize($array)
    {
        $count = count($array);
        $repeat = $this->xml_tags($array);
        $repeatedone = false;
        $tags = array();
        $k = 0;
        for ($i = 0; $i < $count; $i++)
        {
                switch ($array[$i]['type']) {
                case 'open':
                    array_push($tags, $array[$i]['tag']);
                    if ($i > 0 && ($array[$i]['tag'] == $array[$i-1]['tag']) && ($array[$i-1]['type'] == 'close'))
                        $k++;
                    if (isset($array[$i]['value']) && ($array[$i]['value'] || !$this->skip_empty_values))
                    {
                        array_push($tags, '@content');
                        $this->array_insert(count($tags), $tags, $array[$i]['value'], "open");
                        array_pop($tags);
                    }
                    if (in_array($array[$i]['tag'] . $array[$i]['level'], $repeat)) {
                            if (($repeatedone == $array[$i]['tag'] . $array[$i]['level']) && ($repeatedone))
                            {
                                array_push($tags, strval($k++));
                            }
                            else
                            {
                                $repeatedone = $array[$i]['tag'] . $array[$i]['level'];
                                array_push($tags, strval($k));
                            }
                    }
                    if (isset($array[$i]['attributes']) && $array[$i]['attributes'] && $array[$i]['level'] != $this->ignore_level) {
                        array_push($tags, '@attributes');
