在布尔模式下全文搜索的foreach循环

Question

I have php code which fetches names of toys from words table and matches these words in toys_text field of toys table using Boolean mode fulltext search and displays names of toys for users and counts of toys and unique users on webpage.

The names of toys can be either one word or combination of words. We want to fetch those results from toys which has toys_text field having all the words of the word combinations from words table

(example - If words table has entry called blue car - BOTH blue and car should be present in the toys table toys_text field for a match). The database changes over time with new toys with their users being added and outdated toys with their users removed.

I am facing issue in properly converting the array to string to input into the Boolean fulltext search. I using foreach loop and want to output +(blue) +(car) but it is only inseting +(car) into the Boolean full text query.

echo $query1 outputs

`select COUNT(*) as 'count', COUNT(DISTINCT tw.screen_name) AS 'cnt' from 
tweets tw join users us on tw.user_id=us.user_id WHERE MATCH (tweet_text) 
AGAINST (' +(car)' IN BOOLEAN MODE)`

while I would like the query to output as

`select COUNT(*) as 'count', COUNT(DISTINCT tw.screen_name) AS 'cnt' from 
tweets tw join users us on tw.user_id=us.user_id WHERE MATCH (tweet_text) 
AGAINST ('+(blue) +(car)' IN BOOLEAN MODE)`

This is my code -

<?php
$query = "SELECT * FROM words ORDER BY `words`.`words` 
ASC";
$result = mysqli_query($con, $query);

$i = 1;            
while($row = mysqli_fetch_array($result)){                        
    $Word = $row['words'];
    $WordsArr = explode(" ", $row['words']);
    $query = "";

       if(count($WordsArr) > 1){
          foreach ($WordsArr as $value) {
                    $value1 = " +"."(".$value."*".")";
                    }
           $query1 = "select COUNT(*) as 'count', COUNT(DISTINCT 
           t.name) AS 'cnt' from toys t WHERE MATCH (toys_text) AGAINST 
          ('$value1' IN BOOLEAN MODE)";
        }else{
        $query1 = "select COUNT(*) as 'count', COUNT(DISTINCT t.name) AS 
       'cnt' from toys t WHERE 
        MATCH (toys_text) AGAINST ('$WordsArr[0]* IN BOOLEAN MODE')";
        }               
        $Data1 = mysqli_query($con, $query1);
        $total1 = mysqli_fetch_assoc($Data1);                     
            ?>                  
        <tr>
          <td><?php echo $i;?></td>
          <td><?php echo $row['words'];?></td>
          <td><a href="showtoys.php?word=<?php echo 
          urlencode($Word); ?>" target="_blank"><?php echo 
          $total1['count']; ?></a></td>
          <td><a href="showtoys.php?keyword=<?php echo urlencode($Word); 
          ?>" target="_blank"><?php echo $total1['cnt']; ?></a></td>                   
        </tr>
            <?php $i++;} ?>

Your problem is that you don't concatenate the string :

foreach ($WordsArr as $value) {
    $value1 = " +"."(".$value."*".")";
}

Should be :

$value1 = '';
foreach ($WordsArr as $value) {
    $value1 .= " +"."(".$value."*".")";
}
