convert a php array to xml

[imen]

Hi,I have a problem, I have an associative array in php that contains multiple sub tables, I want to convert it into xml and especially simplexml, but I think I have a problem with everything accent special character, etc. they told me to change the encoding "ISO-8859-1", but it does not work, can you help me please??

 

function arrayToXML( SimpleXMLElement &$xml, $array ) {

foreach( $array as $name => $value ) {

if( !is_array($value) )

//$xml->addChild( $name, $value );

$xml ->$name = $value;

else {

$child = $xml->addChild( $name );   

arrayToXML( $child, $value );

}

}

}

echo arrayToXML($xml_page_info,$wall)->asXML();

exit( ) ;

?>

Here is the array

All of the & characters in your strings must be converted to entities. For example, & becomes &

 

You can do this with htmlentities()

But only the &s. If you use htmlentities() or htmlspecialchars() then you'll be double-encoding some characters.

imen, are you sure you posted the right code? The error message talks about the value given to addChild() but the only time you call that you don't provide the value.

[cpd]

And you're not ever returning anything from arrayToXML so calling asXML() on it will just raise an error.

hi still alivei thank you for your answer, I change the code with htmlspecialchars() , but it shows this error

 

 

Fatal error : Call to une fonction asXML membre () sur un non-objet dans C: \ Program Files (x86) \ EasyPHP-5.3.9 \ www \ fbcnx.php on line 14

 

<?php

$xml = new SimpleXMLElement( '<pageinfo/>' );

// function call to convert array to xml

function arrayToXML( SimpleXMLElement &$xml, $array ) {

foreach( $array as $name => $value ) {

if( !is_array($value) )

$xml->addChild( $name, htmlspecialchars($value ));

 

else {

$child = $xml->addChild( $name );   

arrayToXML( $child, $value );

}

}

}

echo (arrayToXML($xml,$wall)->asXML());

exit( ) ;

?>

ah oki,thanks

Its very simple to fix. Return the SimpleXMLElement and then perform the ->asXML() method on it...

[imen]

I modified my code but it shows me this error

 

 

Fatal error : Call to une fonction asXML membre () sur un non-objet dans C: \ Program Files (x86) \ EasyPHP-5.3.9 \ www \ fbcnx.php on line 14 

 

my code is:

 

<?php

$xml_page_info = new SimpleXMLElement( '<pageinfo/>' );

// function defination to convert array to xml

 function array_to_xml($student_info, &$xml_page_info)

{

    foreach($student_info as $key => $value) {

        if(is_array($value)) {

            if(!is_numeric($key)){

                $subnode = $xml_page_info->addChild("$key");

                array_to_xml($value, $subnode);

            }

            else{

                array_to_xml($value, $xml_page_info);

            }

        }

        else {

            $xml_page_info->addChild($key,$value);

        }

    }

return $xml_page_info;

} 

echo array_to_xml($xml_page_info,$wall)->asXML();

exit( ) ;

 

?>

[cpd]

Dude, seriously... read the god damn answers people are giving you!

[imen]

sorry,but I did not understand

You are getting the non-object error because of this line

echo array_to_xml($xml_page_info,$wall)->asXML();

You have your parameters backwards... According to this line

 function array_to_xml($student_info, &$xml_page_info)

$xml_page_info goes at the end.

[Zane]

I went to google and searched for "undetermined entity reference" and the first result, which was the PHP manual,  was this

6 years ago

To avoid warning message "unterminated entity reference" you may use htmlentities() for escaping supplied value:
<?php
//...
$dom->createElement('name', htmlentities($text))
//...
?>

 

Omit the fact that it shows up at the very bottom of the page.  Ctrl+F is your best friend in searching for information.
