Search for each word in different columns in the same table with one query

I have string

:

$searchkey="a b c";

      

        
        
        
      

    

I have three columns:

$column=array('column1','column2','column3');

      

        
        
        
      

    

I want to check every word in this column and get one query row. To get it I did the following ... but it doesn't look the way I want it ... I am very new to PHP so I am a stack. Can you help solve this or any other easy way to get a single query string?

$searchkey="a b c";
$words = EXPLODE(" ",$searchkey);
$column=array('column1','column2','column3');

foreach($column as $column){    
   for($i=0; $i<count($words); $i++){
       $string1.=''.$column.' like %'.$words[$i].'% or ';
   }
   $string1 = SUBSTR($string1,0,STRLEN($string1)-4);
   $string2.= '('.$string1.') or ';

}
echo $string2= SUBSTR($string2,0,STRLEN($string2)-4);

      

        
        
        
      

    

This gives me:

(column 1 like% a% or column 1 like% b% or column 1 like% c%) or (column1 like% a% or column1 like% b% or column 1 like% c% column2 like% a% or column2 like% b% or column2 like% c%) or (column 1 like% a% or column1 like% b% or column 1 like% c% column2 like% a % or column2 like% b% or column2 like% c% column3 like% a% or column3 like% b% or column3 like% C%)

However, I would like to get:

(column 1, such as% a% or column 1, such as% b%, or column 1, such as% c%) or (column2, such as% a%, or column2, such as% b%, or column2, such as% c%) or (column 3 like% a% or column3 like% b% or column3 like% c%)

Thanks in advance.
