php - Fetching a json_encoded array exhausts memory -


i have 2 arrays form inputs trying combine , store in single database cell. able this, when trying retrieve it, gives fatal error of exhausting memory limit.

i inserting main slider has additional slides within it. kind of. don't want create individual sql tables, maybe need to.

my memory @ 256mb, know increase more i'd rather figure out why large.

so inputs coming from:

<fieldset class="form-group">   <label class="label-top" for="scroll-content[]">scroll text #1</label>   <textarea rows="5" cols="50" name="scroll-content[]" id="scroll-content-"></textarea>   <input type="hidden" name="slide-number[]" value="1"> </fieldset>  <fieldset class="form-group">   <label class="label-top" for="scroll-content[]">scroll text #2:</label>   <textarea rows="5" cols="50" name="scroll-content[]" id="scroll-content-"></textarea>   <input type="hidden" name="slide-number[]" value="2"> </fieldset>

inserting:

function add_new_scroll($dir, $plugin_id) {      // configure content array     $num = $_post['slide-number'];     $array = $_post['scroll-content'];     $combined = array_combine($num, $array);      $content = json_encode($combined);      // global connection     global $conn;     wj_connect();      // sql     $sql = "insert `scroll_text` (`scroll_order`, `num_slides`, `scroll_title`, `scroll_slug`, `scroll_content`)                 values(?,?,?,?,?)                 on duplicate key update                     `scroll_order` = values(`scroll_order`),                     `num_slides` = values(`num_slides`),                     `scroll_title` = values(`scroll_title`),                     `scroll_slug` = values(`scroll_slug`),                     `scroll_content` = values(`scroll_content`)";      if ($stmt = $conn->prepare($sql)) {          $stmt->bind_param("iisss", $ansp_order, $ansp_num_slides, $ansp_title, $ansp_slug, $ansp_content);          // set params         $ansp_order = 0;         $ansp_num_slides = 1;         $ansp_title = $_post['scroll-title'];         $ansp_slug = $_post['scroll-slug'];         $ansp_content = $content;          $stmt->execute();         $stmt->close();      } else {         echo 'scroll text not added.';     }      $conn->close();     header("location: ". $dir . "/scroll-text-admin.php?plug_id=" . $plugin_id . "&type=edit&slug=" . $ansp_slug); }

stores like:

{"1":"<p>1<\/p>","2":"<p>2<\/p>"}

retrieving:

function return_scroll() {      // global connection     global $conn;     wj_connect();      // sql     $sql = "select `id`, `scroll_order`, `num_slides`, `scroll_title`, `scroll_slug`, `scroll_content`                 `scroll_text` `scroll_slug` = ? limit 1";      if ($stmt = $conn->prepare($sql)) {          $stmt->bind_param("s", $rsp_slug);         $rsp_slug = $_get['slug'];          $stmt->execute();          // bind results         $stmt->bind_result($rsr_id, $rsr_order, $rsr_num_slides, $rsr_title, $rsr_slug, $rsr_content);          $scroll = array(             'id' => $rsr_id,             'order' => $rsr_order,             'num_slides' => $rsr_num_slides,             'title' => $rsr_title,             'slug' => $rsr_slug,             'content' => $rsr_content             );          $stmt->fetch();         $stmt->close();     }      $conn->close();      return $scroll; }

error!:

fatal error: allowed memory size of 268435456 bytes exhausted (tried allocate 4294967296 bytes) in /home/wonderadmin/public_html/wj-admin/plugins/scroll-text/scroll-text.php on line 199
