[英]PHP reading MySQL query results into an array
I am currently running a MySQL query to return song titles from a database. 我目前正在运行MySQL查询,以从数据库返回歌曲名称。 Each song title returned displays on a different line when I echo
the results. 当我echo
显结果时,返回的每个歌曲标题将显示在不同的行上。 I would like to return the song titles as an array and then echo
that array. 我想将歌曲标题作为数组返回,然后echo
该数组。
Example output: songTitle1 songTitle2 songTitle3 输出示例:songTitle1 songTitle2 songTitle3
What I am looking for: Array ([1] => songTitle1 [2] => songTitle2) and so on 我正在寻找的是:数组([1] => songTitle1 [2] => songTitle2),依此类推
Thanks. 谢谢。
Here is my PHP script: 这是我的PHP脚本:
<?php
$varusername = $_POST['username'];
//connection string
$connection=mysqli_connect(<server_details>);
//check connection
if(!$connection)
{die("Failed to connect to MySql:".mysqli_connect_error());}
else
$query = "SELECT Title FROM songs WHERE Uusername='$varusername'";
$result = $connection->query($query);
if ($result->num_rows > 0){
while($row = $result->fetch_assoc()){
echo $row["Title"]. "<br>";
}
}
else
{die('SQL Error:'.mysqli_error($connection));}
mysqli_close($connection);
?>
You can create an array
before the while loop runs and then use array_push
to add each song item (or just the title) onto it. 您可以在while循环运行之前创建一个array
,然后使用array_push
将每个歌曲项(或只是标题)添加到array
。 From there use print_r($array)
, var_dump($array)
or json_encode($array)
to echo the array (as you cannot echo an array out directly). 从那里使用print_r($array)
, var_dump($array)
或json_encode($array)
回显数组(因为您不能直接回显数组)。
Example code snippet: 示例代码段:
$result = $connection->query($query);
$songsArray = array();
if ($result->num_rows > 0){
while($row = $result->fetch_assoc()){
array_push($songsArray, $row);
}
}
echo print_r($songsArray);
echo var_dump($songsArray);
echo json_encode($songsArray);
