需要通过PHP文件

Question

我使用PHP文件检索从MySQL服务器的数据改变mysqli_query输出格式，输出是：

Array ([0] => Abbasya [1] => Alex Auto [2] => Alex Post [3] => Banisweif [4] => Nasr City [5] => Ramsis TE [6] => Smart Village). 

我需要改变输出到像下面的我需要在我的android应用程序中将字符串转换为字符串[]。

需要输出（只打印值）：

"Abbasya", "Alex Auto", "Alex Post", "BaniSweif", "Nasr City", "Ramsis TE", "Smart Village" 

什么是对下面的PHP代码所需要的改变来产生所需的输出

<?php 
require "init.php"; 
$query = mysqli_query($con,"SELECT core_site FROM core_sites"); 
$coresites = []; 
while($row = mysqli_fetch_assoc($query)){ 
$coresites[] = $row['core_site']; 
} 
print_r($coresites); 
?> 

的支持非常感谢:)

试试这个

require "init.php"; 
$query = mysqli_query($con,"SELECT core_site FROM core_sites"); 
$coresites = []; 
while($row = mysqli_fetch_assoc($query)){ 
$coresites[] = $row['core_site']; 
} 
echo json_encode($coresites); 

// or 

echo implode($coresites);
