Post Array from iOS app to enter values in database via PHP File -

i need add values in database table via php file have values in dynamic array can have one,two or more 3 values, on clicking button in ios application sending array via post using ashihttprequest in database value not getting entered. value getting in log nslog(@"selected values %@",self.arrayvalue);

@property (nonatomic, retain) nsmutablearray *arrayvalue;:

selected values (     1,     2 ) 

i using code :

 request = [asiformdatarequest requestwithurl:url];  [request setpostvalue:id forkey:@"userid"];  [request setpostvalue:self.arrayvalue forkey:@"svalueid"];   [request setcompletionblock:^{        nsstring *response = [request responsestring];     response = [request responsestring];     nslog(@"server response: %@", response);     // response shows value has been entered in db shows 0 in value of "svalueid" , userid desired value. 

in php code :

<?php  // array json response $response = array(); //$svalueid=array();   // check required fields if (isset($_request['userid']) && isset($_request['svalueid'])) {   $userid = $_request['userid'];   $svalueid = explode(",",$_request['svalueid']);   include 'connect.php';   // connecting db $db = new db_connect();               $result = mysql_query("select userid, svalueid             users             userid = '$userid'");       if (mysql_num_rows($result) > 0) {       $result = mysql_query("delete uses userid = '$userid'");        foreach($svalueid $value){  $result = mysql_query("insert users(id, userid, svalueid) values('','$userid', '$value')");                                        }  }     else     {       foreach($svalueid $value){  $result = mysql_query("insert users(id, userid, svalueid) values('','$userid', '$value')");   }     }    // check if row inserted or not if ($result) {     // inserted database     $response["success"] = 1;     $response["message"] = "successful.";      // echoing json response     echo json_encode($response); } else {     // failed insert row     $response["success"] = 0;     $response["message"] = "an error occurred.";      // echoing json response     echo json_encode($response); }    } else {     // required field missing     $response["success"] = 0;     $response["message"] = "field's missing";      // echoing json response     echo json_encode($response); } ?> 

but get's value = 0 in field of svalueid in db table don't know php deep. please can 1 me out how should send array values database tables.

i tried sending data in json format able implement it.

 nsmutabledictionary *jsondict = [[nsmutabledictionary alloc] init];     nsmutabledictionary *tagdata = [[nsmutabledictionary alloc] init];     for(int = 0; < arrayvalue.count; i++)     {         nsstring *keystring = [nsstring stringwithformat:@"%i", i];         [tagdata setobject:[arrayvalue objectatindex:i] forkey:keystring];      }      [jsondict setobject:tagdata forkey:@"svalueid"];        nsdata *jsondata = [nsjsonserialization datawithjsonobject:jsondict options:nsjsonwritingprettyprinted error:nil];     nsstring *jsonstring = [[nsstring alloc] initwithdata:jsondata encoding:nsutf8stringencoding];  [request setpostvalue:id forkey:@"userid"];  [request setpostvalue:jsonstring forkey:@"svalueid"]; 

and on console getting value nslog(@"json json string going on server %@",jsonstring);

 json string going on server {   "svalueid" : {     "0" : 1,     "1" : 2   } } 

please don't know if it's correct or not , how should modify php file please need in this. please if did wrong in code can correct it.

$svalueid json string key=>value pairs foreach statements should this:

foreach($svalueid $key=>$value) 

instead of this:

foreach($svalueid $value) 

the queries need updated correctly use $key , $value variables. don't know numbers represent in json string i'm not sure how give corrected query.
