How to remove array index on the basis of searching a string

Question

Say I have a array like

    Array 
(
  [0] => Array ( [name] => test1 [type] => this1 [location] => 1 ) 
  [1] => Array ( [name] => test2 [type] => this2 [location] => 2 )
  [2] => Array ( [name] => testing2 [type] => this3 [location] => 3 )
)

and I want to remove the the key where anywhere it the array it contains the word "testing" doesn't have to be a exact match as long as it has that word.

so ideally [2] should be removed/unset because it contains that word. How can I achieve this.

Expected output:

    Array 
(
  [0] => Array ( [name] => test1 [type] => this1 [location] => 1 ) 
  [1] => Array ( [name] => test2 [type] => this2 [location] => 2 )
)

Thank you

Hope this will help you out.. Here we are using implode and stristr , we are joining an array into string using implode and searching string using stristr

Try this code snippet here

ini_set('display_errors', 1);

$rows=Array ( 
    0 => Array ( "name" => "test1","type" => "this1", "location" => 1 ),
    1 => Array ( "name" => "test2" ,"type" => "this2", "location" => 2 ),
    2 =>Array ( "name" => "testing2","type" => "this3", "location" => 3 ));
$wordToSearch="testing";
foreach($rows as $key => $value)
{
    if(stristr(implode("", $value), $wordToSearch))
    {
        unset($rows[$key]);
    }
}
print_r($rows);

Whilst this code snippet is welcome, and may provide some help, it would be greatly improved if it included an explanation of how it addresses the question. Without that, your answer has much less educational value - remember that you are answering the question for readers in the future, not just the person asking now! Please edit your answer to add explanation, and give an indication of what limitations and assumptions apply.

this code will work for you

 $search = "testing";
 $b =array(array ( 'name' => "test1", 'type' => "this1", 'location' => 1 ) ,
        array ( 'name' => "test2" ,'type' => "this2", 'location' => 2 ) ,
     array ( 'name' => "testing2", 'type'=> "this3", 'location' => 3 ));
foreach ($b as $key=>$val)    {    
   foreach($val as $key1=>$val1){
      if (strpos($val1,$search) !== FALSE) { 
         unset($b[$key]);
         break;
      }
   }
}
echo '<pre>';print_r($b);
