尝试在 XML 文档中嵌入 SQL 查询（PHP 变量）的答案

Question

Hi So this is my first time posting something here, been working on this for a few days but no luck. Basically I am querying a database in php, getting my answer but I want to send this answer to an XML file for graph creation. Any help would be greatfully appreciated.

Here is the part of the PHP file with embedded sql that returns variable.

$result = mysqli_query($con,
"SELECT COUNT(*) as FullCount 
FROM DailyShpm 
WHERE (curr_date between '2013-01-01' and now()- INTERVAL 1 YEAR) 
AND (Product= 'AE')
");

while($row = mysqli_fetch_array($result)) {
echo $row['FullCount'] ;
echo "<- Full results for total AE to date for 2013";
echo "<br>";
echo $row['FullCount'] ;
echo "<br>";


$files ="data.xml";

//load xml object
$xml= simplexml_load_file($files);

//assign value

$xml->set->value = $row['FullCount'];
//$xml->chart ->set = $row['FullCount'];


//store the value into the file
file_put_contents($file, $xml->asXML());
}

Here is what it outputs in the xml file

<?xml version="1.0" encoding="ISO-8859-1"?>

<chart caption="Year to Date" xAxisName="Year" yAxisName="Amount of Shipments Air Exports"> 



<set label="2013" value=""><value>7707</value></set> 
<set label="2014" value=""/> 

I need the value of 7707 to be put in the value within set label="2013" value"7707"

Thanks in advance

Change the following:

$xml->set->value = $row['FullCount'];

to:

$xml->attributes()->value = ((string) $xml->attributes()->value) . $row['FullCount'];
