为MySQL结果设置用户变量

Question

I need help with setting user variables for MySQL result.

SELECT ptype, COUNT(ptype) FROM `TABLE 2` GROUP BY ptype ORDER BY COUNT(ptype)

I would like to create a user variable for resulting value of all the types(TD= 5 ,DT= 13 ,...,etc)

How would I go about this?

dw

 <?$connector=mysqli_connect("localhost","", "",""); $res2=mysqli_query($connector, "SELECT ptype, COUNT(ptype) FROM `TABLE 2` GROUP BY ptype"); for (i = 0; i <12; i++) { $carrier[i] = while ($row=mysqli_fetch_array($res3)) {echo $row['COUNT(carrier)'];} } 

Answer 1

Try:

$ptype = array();
if($res2=mysqli_query($connector, "SELECT ptype, COUNT(ptype) AS pnum FROM TABLE 2 GROUP BY ptype")){
  while($row=mysqli_fetch_array($res2)) {
    $ptype[] = $row['pnum'];
  }
} else {
  printf("Error: %s\n", mysqli_error($connector));
}
