PHP / MySQL中的多词搜索(Multi word search in PHP/MySQL)

 我努力创建搜索多个单词的搜索。 我的第一次尝试没有得到任何结果，如下所示： 
 
  require_once('database_conn.php');
  if($_POST){
  $explodedSearch = explode (" ", $_POST['quickSearch']);


  foreach($explodedSearch as $search){
  $query = "SELECT * 
            FROM jobseeker 
            WHERE forename like '%$search%' or surname like '%$search%' 
            ORDER BY userID 
            LIMIT 5";
  $result = mysql_query($query);
}

while($userData=mysql_fetch_array($result)){
    $forename=$userData['forename'];
    $surname=$userData['surname'];
    $profPic=$userData['profilePicture'];
    $location=$userData['location'];

    echo "<div class=\"result\">
    <img class=\"quickImage\" src=\"" . $profPic. "\" width=\"45\" height=\"45\"/>
    <p class=\"quickName\">" . $forename . " " . $surname . "</p>
    <p class=\"quickLocation\"> " . $location . "</p>
    </div>";

}
}  
 
 我也尝试了以下方法，并取得了结果，但正如您所想的那样，我输入的每个单词都有重复的结果： 
 
if($_POST){
$explodedSearch = explode (" ", $_POST['quickSearch']);


foreach($explodedSearch as $search){
$query = "SELECT * 
          FROM jobseeker 
          WHERE forename like '%$search%' or surname like '%$search%' 
          ORDER BY userID 
          LIMIT 5";
$result .= mysql_query($query);


while($userData=mysql_fetch_array($result)){
    $forename=$userData['forename'];
    $surname=$userData['surname'];
    $profPic=$userData['profilePicture'];
    $location=$userData['location'];

    echo "<div class=\"result\">
    <img class=\"quickImage\" src=\"" . $profPic. "\" width=\"45\" height=\"45\"/>
    <p class=\"quickName\">" . $forename . " " . $surname . "</p>
    <p class=\"quickLocation\"> " . $location . "</p>
    </div>";
}
}
}
 
 我几乎不知道如何继续这一点，任何帮助将不胜感激。 
 
 编辑： 
 
if($_POST){
$quickSearch = $_POST['quickSearch'];
$explodedSearch = explode (" ", trim($quickSearch));


$queryArray = array();

foreach($explodedSearch as $search){
$term = mysql_real_escape_string($search);
$queryArray[] = "forename like '%" . $term .  "%' surname like '%" . $term . "%'";
}

$implodedSearch = implode(' or ', $queryArray);

$query="SELECT *
        FROM jobseeker
        WHERE ($implodedSearch)
        ORDER BY userID
        LIMIT 5";

$result = mysql_query($query);

while($userData=mysql_fetch_array($result, MYSQL_ASSOC)){
    $forename=$userData['forename'];
    $surname=$userData['surname'];
    $profPic=$userData['profilePicture'];
    $location=$userData['location'];


    echo "<div class=\"result\">
    <img class=\"quickImage\" src=\"" . $profPic. "\" width=\"45\" height=\"45\"/>
    <p class=\"quickName\">" . $forename . " " . $surname . "</p>
    <p class=\"quickLocation\"> " . $location . "</p>
    </div>";

}
}

I'm struggling to create a search that searches for multiple words. My first attempt yielded no results whatsoever and is as follows:
 
  require_once('database_conn.php');
  if($_POST){
  $explodedSearch = explode (" ", $_POST['quickSearch']);


  foreach($explodedSearch as $search){
  $query = "SELECT * 
            FROM jobseeker 
            WHERE forename like '%$search%' or surname like '%$search%' 
            ORDER BY userID 
            LIMIT 5";
  $result = mysql_query($query);
}

while($userData=mysql_fetch_array($result)){
    $forename=$userData['forename'];
    $surname=$userData['surname'];
    $profPic=$userData['profilePicture'];
    $location=$userData['location'];

    echo "<div class=\"result\">
    <img class=\"quickImage\" src=\"" . $profPic. "\" width=\"45\" height=\"45\"/>
    <p class=\"quickName\">" . $forename . " " . $surname . "</p>
    <p class=\"quickLocation\"> " . $location . "</p>
    </div>";

}
}  
 
I also tried the following, which yielded results, but as you can imagine, I was getting duplicate results for every word I entered:
 
if($_POST){
$explodedSearch = explode (" ", $_POST['quickSearch']);


foreach($explodedSearch as $search){
$query = "SELECT * 
          FROM jobseeker 
          WHERE forename like '%$search%' or surname like '%$search%' 
          ORDER BY userID 
          LIMIT 5";
$result .= mysql_query($query);


while($userData=mysql_fetch_array($result)){
    $forename=$userData['forename'];
    $surname=$userData['surname'];
    $profPic=$userData['profilePicture'];
    $location=$userData['location'];

    echo "<div class=\"result\">
    <img class=\"quickImage\" src=\"" . $profPic. "\" width=\"45\" height=\"45\"/>
    <p class=\"quickName\">" . $forename . " " . $surname . "</p>
    <p class=\"quickLocation\"> " . $location . "</p>
    </div>";
}
}
}
 
I'm pretty much at a loss as to how to proceed with this, any help would be greatly appreciated.
 
EDIT:
 
if($_POST){
$quickSearch = $_POST['quickSearch'];
$explodedSearch = explode (" ", trim($quickSearch));


$queryArray = array();

foreach($explodedSearch as $search){
$term = mysql_real_escape_string($search);
$queryArray[] = "forename like '%" . $term .  "%' surname like '%" . $term . "%'";
}

$implodedSearch = implode(' or ', $queryArray);

$query="SELECT *
        FROM jobseeker
        WHERE ($implodedSearch)
        ORDER BY userID
        LIMIT 5";

while($userData=mysql_fetch_array($result, MYSQL_ASSOC)){
    $forename=$userData['forename'];
    $surname=$userData['surname'];
    $profPic=$userData['profilePicture'];
    $location=$userData['location'];


    echo "<div class=\"result\">

    <p class=\"quickName\">" . $forename . " " . $surname . "</p>

    </div>";
