How to convert array to SimpleXML

Question

How can I convert an array to a SimpleXML object in PHP?

Answer 1

I use a couple of functions that I wrote a while back to generate the xml to pass back and forth from PHP and jQuery etc... Neither use any additional frameworks just purely generates a string that can then be used with SimpleXML (or other framework)...

If it's useful to anyone, please use it :)

function generateXML($tag_in,$value_in="",$attribute_in=""){
    $return = "";
    $attributes_out = "";
    if (is_array($attribute_in)){
        if (count($attribute_in) != 0){
            foreach($attribute_in as $k=>$v):
                $attributes_out .= " ".$k."=\"".$v."\"";
            endforeach;
        }
    }
    return "<".$tag_in."".$attributes_out.((trim($value_in) == "") ? "/>" : ">".$value_in."" );
}

function arrayToXML($array_in){
    $return = "";
    $attributes = array();
    foreach($array_in as $k=>$v):
        if ($k[0] == "@"){
            // attribute...
            $attributes[str_replace("@","",$k)] = $v;
        } else {
            if (is_array($v)){
                $return .= generateXML($k,arrayToXML($v),$attributes);
                $attributes = array();
            } else if (is_bool($v)) {
                $return .= generateXML($k,(($v==true)? "true" : "false"),$attributes);
                $attributes = array();
            } else {
                $return .= generateXML($k,$v,$attributes);
                $attributes = array();
            }
        }
    endforeach;
    return $return;
}   

Love to all :)
