I want to produce search result all letters that is caps or small,but now it's displaying exact keywords result only,so that i changed my original code $pattern = "/".$searchTerm."([a-zA-Z0-9])*/"; to like this $pattern = "/".$searchTerm."([a-zA-Za-ZA-z0-9])*/";
but this display some errors and output not coming
Error :
Warning: preg_match_all(): Compilation failed: range out of order in character class at offset 14 in /var/app/current/WS/search.php on line 30
Warning: Invalid argument supplied for foreach() in /var/app/current/WS/search.php on line 31 {"message":"success","response":1,"result":[]}
My search code :
if($searchTerm&&$searchType)
    {
        if($searchType=='hash') {
            $query = "SELECT hashTag FROM `".$table."` WHERE hashTag LIKE '%#".$searchTerm."%'";
            $stmt = $database->prepare($query);
            // $stmt->bind_param('s',$searchTerm);
            $stmt->execute();    
            $stmt->store_result();
            if($stmt->num_rows>0) {
                $tempArray = array();
                $stmt->bind_result($hashTag);
                while ($row =$stmt->fetch()) {
                    $pattern = "/".$searchTerm."([a-zA-Za-ZA-z0-9])*/";
                    preg_match_all($pattern,$hashTag,$matches);
                    foreach ($matches[0] as $key => $value) {
                        $finalArray[$value] = "";
                    }
                }
                foreach ($finalArray as $key => $value) {
                    $tempArray = array();
                    $tempArray['hash'] = $key ;
                    array_push($megaArray, $tempArray);
                }       
                $stmt->free_result();
                $stmt->close();
                $finalArray = array();
                $finalArray = $megaArray;
                $message = "success";
                $response = 1;
            } 
        }
What is the solution to produce the result to the search term is caps or small?
