将键值对从数据库添加到php关联数组

Question

DB is set up as such:

include 'php/DbConnect.php';
$sql = $mysqli->query(
 "SELECT t.*, v.* 
 FROM task t 
 INNER JOIN vocabtask vt ON (t.id = vt.taskid)
 INNER JOIN vocab v ON (v.id = vt.vocabid)
 WHERE vt.taskid = 1");
$wordsArray = array();  


while ($row = $sql->fetch_assoc()) {

   // echo "<br> " . $row['taskname'] . ": ".  $row['chinese'] . " : " . $row['english'];
    $wordsArray['chinese']['english'] = $row['chinese'];
    echo $wordsArray['chinese']['english'];
}
mysqli_close($mysqli);  

Output: Ni Ta Wo

Desired output: Ni: You Ta: Him Wo: I

I want the Chinese word (key) and associated English translation (value) loaded into wordsArray, but don't know the correct syntax to load and to access.

Thanks

Answer 1

Perhaps you want this? It maps one direction, Chinese to English, but there's not a really great way to do bidirection mapping as far as I know. (Typically I use two mappings to do that.) edit: It seems this is the direction you want, based on your edit.

$wordsArray = array();
while ($row = $sql->fetch_assoc()) {
    $wordsArray[$row['chinese']] = $row['english'];
}
mysqli_close($mysqli);  
var_dump($wordArray);

Answer 2

$json = array();
foreach (...) {
    $json[$row['chinese']] = $row['english']
}

$return_result = json_encode($json);

echo $return_result;

you may grab that return value with jQuery and parse it as jSON with jQuery.parseJSON() with/without ajax.

update, if you don't want parse the data with ajax just add the result to the page within a script tag like

<script type="text/javascript">
(function($){
    var data = '<?php echo $return_result; ?>';
    var json = $.parseJSON(data);
    console.log(json);
})(jQuery);
</script>
