Question

I am new in this json chapter.I have a file named mysql_conn.php .This file have a php function to call data from mysql database.So can anyone help me to create one json file to get data from mysql_conn.php.Below is my code
mysql_conn.php
function getWrkNoTest($wrkno){
$conf = new BBAgentConf();
$log = new KLogger($conf->get_BBLogPath().$conf->get_BBDateLogFormat(), $conf->get_BBLogPriority() );
$connection = MySQLConnection();
$getWrkNoTest ="";
$lArrayIndex = 0;
$query = mysql_query("
SELECT
a.jobinfoid,
a.WRKNo,
a.cate,
a.det,
a.compclosed,
a.feedback,
a.infoID,
b.callerid,
b.customername
FROM bb_jmsjobinfo a
LEFT JOIN bb_customer b
ON a.customerid = b.customerid
WHERE a.WRKNo = '$wrkno';"
);
$result = mysql_query($query);
$log->LogDebug("Query[".$query."]");
while ($row = mysql_fetch_array($result)){
$getWrkNoTest = array("jobinfoid"=>$row['jobinfoid'],
"WRKNo"=>$row['WRKNo'],
"cate"=>$row['cate'],
"det"=>$row['det'],
"compclosed"=>$row['compclosed'],
"feedback"=>$row['feedback'],
"infoID"=>$row['customerid'],
"customerid"=>$row['infoID'],
"callerid"=>$row['callerid'],
"customername"=>$row['customername']);
$iList[$lArrayIndex] = $getWrkNoTest;
$lArrayIndex = $lArrayIndex + 1;
}
$QueryResult = print_r($getWrkNoTest,true);
$log->LogDebug("QueryResult[".$QueryResult."]");
closeDB($connection);
return $iList;
}
json.php
if ($_GET['action']=="getJsonjms"){
$wrkno = $_GET["wrkno"];
if($wrkno != ""){
$jms = getWrkNoTest($wrkno);
if(!empty($jms)){
echo json_encode($jms);
}else{
echo "No data.";
}
}else{
echo "Please insert wrkno";
}
}
I dont know how to solve this.Maybe use foreach or something else.Sorry for my bad english or bad explanation.I'm really new in this json things. Any help will appreciate.Thanks

Answer 1

If I understand your question right, you want to convert the results you receive from your MySQL query into JSON and then store that data into a file?
If this is correct, you can build off of what you currently have in json.php. In this block here, you use json_encode():
if(!empty($jms)){
echo json_encode($jms);
}
We can take this data and pass it to file_put_contents() to put it into a file:
if (!empty($jms)) {
$json = json_encode($jms);
// write the file
file_put_contents('results.json', $json);
}
If this is a script/page that's visited frequently, you'll want to make the filename (above as results.json) into something more dynamic, maybe based on the $wrkno or some other schema.
