在php mysql中回显while语句外的多个字段

Question

Sorry if look silly as i am a beginner

I am comparing id's and displaying data .

Expected output

Name1 Name2 Name3

Code.

$cout = mysql_query("SELECT * FROM student where parent_id='$update_id' ",$link);
while($cput = mysql_fetch_array($cout)){
  echo $cput['s_name'];   
}

But, i want to echo outside while loop, so i tried the following but it outputs only the last value i.e., Name3

$cout = mysql_query("SELECT * FROM student where parent_id='$update_id' ",$link);
while($cput = mysql_fetch_array($cout)){
  $sname = $cput['s_name'];
}
echo $sname;

I can understand that the loop will terminate after while loop and hence it won't do the required one . But, i think that there might be a work around . Anyone can help me over here please.

Answer 1

Define a variable to keep names with space separated ($sname) then concatenate s_name value in each iteration like $sname .= $cput['s_name'] . ' ';

So your code will be like...

$cout = mysql_query("SELECT * FROM student where parent_id='$update_id' ",$link);
$sname = '';
while($cput = mysql_fetch_array($cout)){
    $sname .= $cput['s_name'] . ' ';
}
echo $sname;
