Question

I want to return a set of values from function till the point they exist….
for example….

function abc($i="3"){

    for($a=1;$a<=$i;$a++) {
        $name='t'.$i;
        $$name = "ae".$a;
    }
    //now i am returning values 
    return array($t1,$t2,$t3,$t4,$t5,$t6,$t7,$t8,$t9,$t10);
    //but i only want to return $t1,$t2,$t3 depending on $i
}

Thanks….

I am also creating an array in the loop , I’ll paste the original code so that you can understand it in a better way

function extracting_comments($table, $fields,$condition,$order,$limit){
        $query="SELECT ".$fields."
                FROM ".$table."
                WHERE ".$condition."
                ORDER BY ".$order."
                LIMIT ".$limit." ";
        if($stmt = $this->conn->prepare($query)) {
            $stmt->execute();
            $row = array_pad(array(), $stmt->field_count, '');
            $params = array();
                foreach($row as $k=>$v) {
                  $params[] = &$row[$k];
                  echo $params[0];
                }
            call_user_func_array(array($stmt,'bind_result'),$params);
            $i=0;
            while($stmt->fetch()) {
            $i++;
            $name='t'.$i;
            $$name = array();
            foreach ($row as $b=>$elem) {
            $atul[$b]=$row[$b];
            }
            $$name=$atul;
            }
            return array($t1,$t2,$t3,$t4,$t5,$t6,$t7,$t8,$t9,$t10);
            $stmt->close();
        }

    }

now their are only 5 rows of data so their is no point returning $t6,$t7,$t8,$t9,$t10
and i want to fix it ,and i am calling the function using

$extract=extracting_comments($table, $fields,$condition,$order,$limit);

please help…thanks

I believe this will help you. You have very complicated code with a lot of side effects and bug, you’d better to consider to redisgn it. Also putting statements after return will no have any effect, since it wouldn’t be invoked.

function extracting_comments($table, $fields,$condition,$order,$limit){
                $query="SELECT ".$fields."
                                FROM ".$table."
                                WHERE ".$condition."
                                ORDER BY ".$order."
                                LIMIT ".$limit." ";
                if($stmt = $this->conn->prepare($query)) {
                        $stmt->execute();
                        $row = array_pad(array(), $stmt->field_count, '');
                        $params = array();
                                foreach($row as $k=>$v) {
                                  $params[] = &$row[$k];
                                  echo $params[0];
                                }
                        call_user_func_array(array($stmt,'bind_result'),$params);
                        $i=0;
                        $result = array();
                        while($stmt->fetch()) {
                        $i++;
                        foreach ($row as $b=>$elem) {
                        $atul[$b]=$row[$b];
                        }
                        $result[]=$atul;
                        }
                        $stmt->close();
                        return $result;
                }

        }
