my problem parsing xml file , file contain information don't want exporting json data. in case want function return json data first '[' caratere php code:

    <?php  class xmltojsonconverter {     public function parsexml ($url) {         $filecontents= file_get_contents($url);         // remove tabs, newline, whitespaces in content array         $filecontents = str_replace(array("\n", "\r", "\t"), '', $filecontents);         $filecontents = trim(str_replace('"', "'", $filecontents));         $myxml = simplexml_load_string($filecontents);         $json = json_encode($myxml);         return $json;     } } //path of xml file $url= 'http://www.lequipe.fr/rss/actu_rss_football.xml';  //create object of class $jsonobj = new xmltojsonconverter();  //pass xml document class function $myjson = $jsonobj->parsexml($url); print_r ($myjson); ?>

this part of json result :

{"@attributes":{"version":"2.0"},"channel":{"title":"l'equipe.fr actu football","link":"http://www.lequipe.fr","description":"l'equipe.fr, toute l'actualit\u00e9 du football","language":"fr","copyright":"copyright l'equipe.fr","pubdate":"wed, 22 apr 2015 16:31:08 +0200","image":{"url":"http://www.lequipe.fr/rss/logo_rss.gif","title":"l'equipe.fr","link":"http://www.lequipe.fr","width":"119","height":"28"},"item":[{"title":"foot - cha

i want result start '['

thank you

remove every attribute don't want before encoding json:

public function parsexml ($url) {     $filecontents= file_get_contents($url);     // remove tabs, newline, whitespaces in content array     $filecontents = str_replace(array("\n", "\r", "\t"), '', $filecontents);     $filecontents = trim(str_replace('"', "'", $filecontents));     $myxml = simplexml_load_string($filecontents);     //--------------     unset($myxml['@attributes']);     unset($myxml['channel']);     unset($myxml['image']);     //--------------     $json = json_encode($myxml);     return $json; }

or if need item:

public function parsexml ($url) {     $filecontents= file_get_contents($url);     // remove tabs, newline, whitespaces in content array     $filecontents = str_replace(array("\n", "\r", "\t"), '', $filecontents);     $filecontents = trim(str_replace('"', "'", $filecontents));     $myxml = simplexml_load_string($filecontents);     //--------------     $json = json_encode($myxml['item']);     return $json; }
