Array2xml classes in PHP convert arrays into XML instances

In this paper, we describe the method of Array2xml class in PHP to transform the array into XML. Share to everyone for your reference. The implementation method is as follows:

<?phpclass array2xml{    var $xml;    function Array2xml ($array, $encoding = ' utf-8 ') {        $this->xml= ' <?xml version= "1.0" encoding= "'. $encoding. '"? > ';        $this->xml.= $this->_array2xml ($array);    }    function getXml () {        return $this->xml;    }    function _array2xml ($array)    {        $xml = ';        foreach ($array as $key = + $val) {            if (is_numeric ($key)) {                $key = "Item id=\" $key \ "";            } else{                //Remove the space, just take the space before the text is the key                list ($key,) =explode (", $key);            }             $xml. = "< $key >";            $xml. =is_array ($val)? $this->_array2xml ($val): $val;            Remove the space, just take the space before the text is the key            list ($key,) =explode (", $key);            $xml. = "</$key >";        }        return $xml;    }}
