Question

您好我正在尝试验证数组并从文本框中插入数据。

但我不想插入重复的值。

e.g

 ######### Inserting first name #####
 $textbox = 'Jose,';

 $textarea = Array();

 $list = explode(',', $list, -1);

  foreach(array_unique($list) as $key){
 if ($textbox != $key){
    insert (Jose,)into textarea;
 }  
 }

（出口）

 ########### second name ######
  $textbox = 'Carlos,';

  $textarea = Array('Jose,');

  $list = explode(',' $list, -1);

  foreach(array_unique($list) as $key){
  if($textbox != $key){
     insert (Carlos,) into textarea;
  }
  }

（出口）

  ########### third name ######
   $textbox = 'Carlos,';

   $textarea = Array('Jose,Carlos,');

   $list = explode(',' $list, -1);

   foreach(array_unique($list) as $key){ 
   if($Carlos != $key){ //$key = Jose
     insert (Carlos,) into textarea;
   } //next
   if($Carlos != $key){ //$key = Carlos
       insert (Carlos,) into textarea;
   }else{
     It exist;
   } 
 }

这是我的代码......

   foreach ( array_unique($viewer) as $viewermi ){
         if ( $userdata['uid'] != $viewermi ){ 
         $objResponse->addAppend('viewerlist', 'value', $userdata['uid'].',');
         $objResponse->addAssign('vieadded', 'value', '');
         $objResponse->addAssign('vadded', 'innerHTML', $user.' Added');
         $objResponse->addScript('$(\'#btViewAdded\').attr(\'disabled\', true)');
         }else{
        $objResponse->addAssign('vadded', 'innerHTML', '');
        $objResponse->addAlert("It uid had been added! ".$viewermi);
        $objResponse->addAssign('vieadded', 'value', '');
        $objResponse->addScript('$(\'#btViewAdded\').attr(\'disabled\', true)');
    } // End If-Else $userdata
 } // End foreach Viewers

任何人都可以帮我这个吗？

我尝试了一些方法，但我无法做到。

  $textbox = 'Carlos,Jose,Carlos,Lauro,Marcos';

  $textarea = array();

  $list = explode(',' , $textbox);

  foreach(array_unique($list) as $key){
     if(!in_array($key , $textarea)){
      $textarea[] = $key;
     }
  }

Array PHP中的唯一值
