adding element in array using array_push( ) in php

Question

for ($i = 0; $i < count($d); $i++){
    $ins_data[$i]=$this->input->post('question_type_rt_'.$i.'');
    $a=array();
    array_push($a,$ins_data[$i]);
    print_r($a);
    echo"<br>";
}

where it gives output

Array ( [0] => 1 )
Array ( [0] => 2 )
Array ( [0] => 1 )
Array ( [0] => 2 )
Array ( [0] => 1 )

but i want all element in same array

and create string from that array

Your array needs to be initialised outside of the for loop to prevent overwriting the reference to it each time you run through the for loop:

$a=array();
for ($i = 0; $i < count($d); $i++){
  $ins_data[$i]=$this->input->post('question_type_rt_'.$i.'');
  array_push($a,$ins_data[$i]);
}
print_r($a);
