Example of the Conversion Function between arrays and XML files implemented by PHP. xml is converted to each other.

This example describes the conversion between arrays and XML files implemented by PHP. We will share this with you for your reference. The details are as follows:

Recently I made a payment. The XML files are returned by the server. Therefore, it is easy to operate only by converting them into arrays. If you do not need to talk about them, directly go to the Code:

1. Convert XML to array

/*** Convert xml into array * @ param string $ xml string or xml file name * @ param bool $ isfile whether the input is an xml file name * @ return array converted array */ function xmlToArray ($ xml, $ isfile = false) {// disable reference of external xml Entity libxml_disable_entity_loader (true); if ($ isfile) {if (! File_exists ($ xml) return false; $ xmlstr = file_get_contents ($ xml);} else {$ xmlstr = $ xml;} $ result = json_decode (json_encode (simplexml_load_string ($ xmlstr, 'simplexmlelement', LIBXML_NOCDATA), true); return $ result ;}

Usage example:

$ XmlDoc = <ETO <books> <book> <author> Jack Herrington </author> <title> PHP Hacks </title> <publisher> O 'Reilly </publisher> </book> <author> Jack Herrington </author> <title> Podcasting Hacks </title> <publisher> O 'Reilly </publisher> </book> <book> <author> XML formatting </author> <title> helper's online tool </title> <publisher> tools.jb51.net </publisher> </book> </books> ETO; $ relarr = xmlToArray ($ xmlDoc); print_r ($ relarr );

Running result:

Array ([book] => Array ([0] => Array ([author] => Jack Herrington [title] => PHP Hacks [publisher] => O 'Reilly) [1] => Array ([author] => Jack Herrington [title] => Podcasting Hacks [publisher] => O 'Reilly) [2] => Array ([author] => XML formatting [title] => online tool for helping customers [publisher] => tools.jb51.net )))

2. Convert arrays to XML

/*** Convert an array to an xml character * @ param string $ xml string **/function arrayToXml ($ data) {if (! Is_array ($ data) | count ($ data) <= 0) {return false;} $ xml = "<xml> "; foreach ($ data as $ key => $ val) {if (is_numeric ($ val) {$ xml. = "<". $ key. "> ". $ val. "</". $ key. ">";} else {$ xml. = "<". $ key. "> <! [CDATA [". $ val. "]> </". $ key. ">" ;}}$ xml. = "</xml>"; return $ xml ;}

Usage example:

$ ArrDoc = array ("author" => "XML formatting", "title" => "", "publisher" => "tools.jb51.net "); $ xmlrel = arrayToXml ($ arrDoc); // running result: <xml> <author> <! [CDATA [XML formatting]> </author> <title> <! [CDATA [online tools for helping customers]> </title> <publisher> <! [CDATA [tools.jb51.net]> </publisher> </xml>
