我有一个对 Json 数据进行编码的 PHP 文件,当我查看 JSON 输出时,当它是一个数据块时,我得到一个有效的 json 代码语法,这是一个示例: 单个数据块
但是当 JSON 产生多个数据块时,它会生成一个无效的 JSON 格式,如下所示:多个数据块
这是我的 PHP 代码:
<?php
header('Content-Type: application/json; charset=utf-8', true,200);
DEFINE('DATABASE_USER', 'xxxxx');
DEFINE('DATABASE_PASSWORD', 'xxxxxx');
DEFINE('DATABASE_HOST', 'xxxxxxxxxxx');
DEFINE('DATABASE_NAME', 'xxxxxxxx');
// Make the connection:
$dbc = @mysqli_connect(DATABASE_HOST, DATABASE_USER, DATABASE_PASSWORD,
DATABASE_NAME);
$dbc->set_charset("utf8");
if (!$dbc) {
trigger_error('Could not connect to MySQL: ' . mysqli_connect_error());
}
if(isset($_GET['keyword'])){//IF the url contains the parameter "keyword"
$keyword = trim($_GET['keyword']) ;//Remove any extra space
$keyword = mysqli_real_escape_string($dbc, $keyword);//Some validation
$query = "select name,franco,alpha,id,url,songkey,chord from song where name like '%$keyword%' or franco like '%$keyword%'";
//The SQL Query that will search for the word typed by the user .
$result = mysqli_query($dbc,$query);//Run the Query
if($result){//If query successfull
if(mysqli_affected_rows($dbc)!=0){//and if at least one record is found
while($row = mysqli_fetch_array($result,MYSQLI_ASSOC)){ //Display the record
$data = array();
$data = $row;
echo $_GET[$callback]. ''.json_encode($data).'';
}
}else {
echo 'No Results for :"'.$_GET['keyword'].'"';//No Match found in the Database
}
}
}else {
echo 'Parameter Missing in the URL';//If URL is invalid
}
?>
