如何限制插入數據到MySql使用codeiginter

Question

如何限制插入數據到MySql使用codeiginter？ 我有10000個陣列數據。 但是我想在每個過程中只限制200個數據。 下一個過程必須從尚未插入的數據中插入。 下面是從控制器我的代碼：

<?php 
foreach($data["result"] as $key) { 

    $insert=$this->db->insert('master_mahasiswa_pt',$key); 
    if (!$insert && $this->db->error()) { 

    echo "Data nim"; echo " "; echo $key['nipd'] ; echo " "; echo "Sudah Ada"; echo '<br>'; 
} else { 
echo "Data nim"; echo " "; echo $key['nipd'] ; echo " "; echo "Sudah Masuk"; echo '<br>'; 
} 
} 
} 
} 
?> 

這裏是從我的陣列數據例如：

Array 
(
    [error_code] => 0 
    [error_desc] => 
    [result] => Array 
     (
      [0] => Array 
       (
        [id_reg_pd] => 35e86b4f-1b8b-407b-b49e-9d125cba2cb5 
        [nipd] => 150015020 
        [id_pd] => b5261e3d-6aed-41e9-a329-1ebe6191d53c 
        [nm_pd] => ACDB 
        [tgl_lahir] => 1996-06-16 
        [id_sms] => 63d9ecdb-4468-4883-a1aa-13ad3f88fce1 
        [fk__sms] => Teknik Informatika                
        [id_sp] => 89a93cb2-f959-45d3-8a75-f349be529b87 
        [fk__sp] => STMIK 
        [tgl_masuk_sp] => 2015-08-25 
        [id_jns_daftar] => 1 
        [fk__jns_daftar] => Peserta didik baru 
        [id_jns_keluar] => 
        [fk__jns_keluar] => 
        [tgl_keluar] => 
        [ket] => 
        [skhun] => 
        [a_pernah_paud] => 0 
        [a_pernah_tk] => 0 
        [mulai_smt] => 20151 
        [sks_diakui] => 0 
        [jalur_skripsi] => 
        [judul_skripsi] => 
        [bln_awal_bimbingan] => 
        [bln_akhir_bimbingan] => 
        [sk_yudisium] => 
        [tgl_sk_yudisium] => 
        [ipk] => 
        [no_seri_ijazah] => 
        [sert_prof] => 
        [a_pindah_mhs_asing] => 
        [nm_pt_asal] => 
        [nm_prodi_asal] => 
       ) 

     ) 

)

$i = 0; 
    foreach ($data["result"] as $key) { 
     if ($i < 201) { 
      $insert = $this->db->insert('master_mahasiswa_pt', $key); 
      if (!$insert && $this->db->error()) { 

       echo "Data nim"; 
       echo " "; 
       echo $key['nipd']; 
       echo " "; 
       echo "Sudah Ada"; 
       echo '<br>'; 
      } else { 
       echo "Data nim"; 
       echo " "; 
       echo $key['nipd']; 
       echo " "; 
       echo "Sudah Masuk"; 
       echo '<br>'; 
      } 
     } 
     $i++; 
    }
