（  
 [冗余] =＆gt;是
 [FILE_NAME] =＆gt; book（2）.pdf

 [2] =＆gt;数组
（
 [冗余] =＆gt;是

Try this,

foreach($files as $key => $file){
   if($file['REDUNDANT'] == "Yes"){
       unset($files[$key]);
   }
}
$files = array_values($files); // Reset key of updated array.

Codepad Demo.

foreach($yourary as $key=>$value)
{
  if($value[REDUNDANT]=="YES")
  {
   unset($yourary[$key]);
  }
}

try this

   $abc= Array
   (
        [0] => Array
        (
              [REDUNDANT] => NO
            [FILE_NAME] => 51894a (2).pdf
            )
      [1] => Array

      foreach($abc as $subKey => $subArray){
      if($subArray['REDUNDANT'] =='yes'){
           unset($abc[$subKey]);
