How to match rows in a MySql table with a JSON data of 200 records as input in PHP -


i have database having 10000 users unique phone numbers.and when ever new user registers i'm trying match contacts (nearly 200 500) existing data can find friends (like whats app)

currently m doing using foreach , slow, need in finding reliable solution can reduce time taken multiple queries.

please find code below m using.

$rawdata= file_get_contents('php://input'); $matchedcontacts = array(); $jsonarray = json_decode($rawdata); foreach ( $jsonarray $value)   {    $contactnumber = ($value->num);   $emil= ($value->email);   $name=mysql_query("select * tbl_user  phone='".$contactnumber ."' or email='".$email."'");   while ($nameres= mysql_fetch_array($name))   {    $matchedcontacts [] = array('username'=>$nameres['username'], 'userid'=>$nameres['c_id']);   }  }  echo json_encode ($matchedcontacts );

edit: i'm passing local id each record i'm sending. after match, how can map matched record particular local id?

you might want consider importing contacts list (temporary?) table, , use join.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
