PHP ships with a function that is pretty well for looking into each array entry for string values and then filtering (or searching) based on a match.

It's part of the pcre based regex extension and called preg_grep.

In your case you pick your $arryTwo input and turn it into a regex pattern. Then this pattern is used to grep the $arrayOne by inverting the matches (that means your matches are removed).

$pattern  = sprintf('~(\\Q%s\\E)~', implode('\\E|\\Q', $arrayTwo));
$filtered = preg_grep($pattern, $arrayOne, PREG_GREP_INVERT);

The result then is a filtered array (demo):

Array
(
    [0] => Aman Namdev Twinkle::how many coast  
    [3] => Aman Nagar::nice 
    [4] => Aarya Kumar::H  
    [5] => Akash Shah::superb 
    ...

As this example output shows here, the entries 1 and 2 are filtered out.

You can use the same function in case you want to offer a search over the chat. Regular expressions are pretty powerful when it comes to strings however they are not always straight forward so take your time to learn about them if you need to deal with string searches more often because then it's valuable for you.

See as well:

Wildcards in array search (Oct 2011) - This Q&A shows how you can use preg_gep with a pattern of your own, for example the SQL LIKE patterns ^MysqlDocs.

Simple foreach

foreach ($arrayone as $key => $value)
{
    foreach ($arraytwo as $keyword)
    {
        if(preg_match('/'.$keyword.'/', $value))
            unset($array[$key]);
    }
}

var_dump($array);

Imagine on the same entry multiple keywords are matching.

Try this.

$temp=array();
$arrayone= array([0]=>..,. ......, [40]=>...);
foreach($arrayone as $key=>$val) {
   for($i=0;$i<count($arraytwo);$i++) {
      $pos = strpos($val, $arraytwo[$i]);
      if($pos === true) {
        $temp[$key] = $val;
      }
   }
}
$result = array_diff($arrayone,$temp);
print_r($result);

Its very simple to use predefine function.....

<?php $array1 = array("a" => "green", "red", "blue", "red"); 
      $array2 = array("b" => "green", "yellow", "red"); 
      $result = array_diff($array1, $array2);
      print_r($result);
?>

output:

Array ( [1] => blue )

    I needed to remove the contents of $array1 from $array2 so I tried:

   <?php 
        $diff    = array_diff($members1, $members2);
   ?> 
   WRONG!! A quick swap around and things worked smoothly...
   <?php  
       $diff    = array_diff($members2, $members1); 
  ?> 
  Hope this saves someone a bit of bother
