hi all,
i have an array called $results; if i print its values(using print_r($results)) i get the values bellow.
My problem is i need to get the value of key, its an array within an array. Does anyone know what im supposed to do.
Array ( [AATSMS] => Array ( [0] => 0 [1] => 2 ) [SUBMITRESULT] => Array ( [0] => 1 ) ) Vals array Array ( [0] => Array ( [tag] => AATSMS [type] => open [level] => 1 ) [1] => Array ( [tag] => SUBMITRESULT [type] => complete [level] => 2 [attributes] => Array ( [ACTION] => enqueued [KEY] => 17730529 [RESULT] => 1 [NUMBER] => 888888888 ) ) [2] => Array ( [tag] => AATSMS [type] => close [level] => 1 ) )
regards

Can you post that in the code snippet - it would be a lot easier to read!

Better yet, print the arrays this way and post the output in the code snippet.  Thanks, ~Ray
echo "<pre>\n";

var_dump($array_thing);

This should do the trick:
$result[1]["attributes"]["KEY"];

I think what JoachimMartinsen posted will do the trick on this set of arrays, but I am curious - this looks like something that was interpreted from an XML file.  In that case (or if the significance of the tag called SUBMITRESULT matters) you might want a more generalized solution rather than just having the numeric index [1].  If you want to tell us more about it, there may be an easy-to-use programmatic solution available.

"Is there a better way of reading xml data" - maybe yes.  I like to use SimpleXML.  It makes the XML into an object and you can use OOP constructs and iterators to access the internals.  If you want to post a sample of the XML, I may be able to show you a way to get this information without the intermediate step of converting it into arrays.

The ending "span" tag is not part of the XML.  Try running this and see what you get.  Please post back here if you have any questions, ~Ray
<?php // RAY_temp_xml_27.php

error_reporting(E_ALL);

echo "<pre>\n";
 

// TEST DATA FROM THE POST AT EE

$xml = '<?xml version="1.0" ?>

<aatsms>

<submitresult action="enqueued" key="3951103" result="1" />

</aatsms>';
 

// MAKE AN OBJECT

$obj = SimpleXML_Load_String($xml);
 

// VISUALIZE THE OBJECT

var_dump($obj);
 

// ITERATE OVER THE OBJECT

foreach ($obj as $thing)

{

// EXTRACT EACH FIELD AND CAST IT AS A STRING VARIABLE

    $action = (string)$thing["action"];

    $key    = (string)$thing["key"];

    $result = (string)$thing["result"];

// SHOW THE VARIABLES WE FOUND

    echo "\nACTION=$action KEY=$key RESULT=$result";

}
