PHP simple web service demo to store JSON Object into database | PHP web service example | PHP GET POST REST Web service example

Hello Friends,
 Below is a simple php code to store JSON object into MySQL database from android client-








1)saveJSONObject.php

<?php
//take the values from client as json
$json = file_get_contents('php://input');
//open database connection
$con = mysql_connect('localhost','root','Manish') or die('Cannot connect to the DB');
mysql_select_db('a4298774_mydb',$con);
//take json values into data variable
$data = json_decode($json);
//get the json values from client in name and number variable
//$name = '".$data->{'name'}."';
//$number= '".$data->{'number'}."' ;

//('".$obj->{'UserName'}."', '".$obj->{'FullName'}."')");
//make a sql query to store data
$sql="INSERT INTO `a4298774_mydb`.`callhistory`(srnumber, name,number)VALUES (NULL,'".$data->{'name'}."', '".$data->{'number'}."')";
$qur=mysql_query($sql);

//check the database response it is true or false
if($qur){
$json=array("status"=>1,"message"=>"done");
}
else{
$json=array("status"=>0,"message"=>"error");
}
//close the database connection
mysql_close($con);
//set header
header('Content-type: application/json');
//print the result as json object
echo json_encode($json);
?>
