将PHP数组解析为Javascript的最佳方法是什么？

Question

I currently have a PHP file that accesses my MySQL database and pulls out the Names and Scores for each player and stores them in an array.

 //This query grabs the top 10 scores, sorting by score and timestamp.
$query = "SELECT * FROM Score ORDER by score DESC, ts ASC LIMIT 10";
$result = mysql_query($query) or die('Query failed: ' . mysql_error());

//We find our number of rows
$result_length = mysql_num_rows($result); 

//And now iterate through our results
for($i = 0; $i < $result_length; $i++)
{
     $row = mysql_fetch_array($result);
     echo $row['name'] . "\t" . $row['score'] . "\n"; // And output them
}

What is the best way for me to get both the name and the score from the PHP File and store them in a Javascript Array?

Answer 1

The best way to store them is store them in json. Use following function

json_encode(arrayname);

and in html use

$.parsejson(responsevariable);

to get original value.

Answer 2

我建议将json_encoded数组提供给javascript变量（json_encode（）），并使用javascript json解码功能，这样您将得到想要的结果：)

Answer 3

Create a result variable

$results = array();

Store your results in it in your loop

array_push($results, array("name" => $row["name"], "score" => $row["score"]));

At the end return it with

echo json_encode($results);

When you get the response on the front end, you can take the response data and JSON.parse() it to turn it into a variable that you can access

var results = JSON.parse(data);

results.forEach(function(result){
    console.log( result.name +" - "+ result.score );
});
