PHP encode_json - 如何将每个编码行分成一个新行？

Question

如何在每个 JSON 编码行上换行？

例如，

header('Content-Type: application/json');

// Specify your sqlite database name and path //
$dir = 'sqlite:testDB.sqlite3';

// Instantiate PDO connection object and failure msg //
$dbh = new PDO($dir) or die("cannot open database");

// Define your SQL statement //
$query = "SELECT * FROM users";

// Iterate through the results and pass into JSON encoder //
foreach ($rows as $row) {
    //var_dump($row);
    echo json_encode($row);
}

结果（一行中的所有行），

{"ID":"1","NAME":"Paul","AGE":"32","ADDRESS":"California","SALARY":"20000.0"}{"ID":"2","NAME":"Allen","AGE":"25","ADDRESS":"Texas","SALARY":"15000.0"}{"ID":"3","NAME":"Teddy","AGE":"23","ADDRESS":"Norway","SALARY":"20000.0"}{"ID":"4","NAME":"Mark","AGE":"25","ADDRESS":"Rich-Mond ","SALARY":"65000.0"}{"ID":"5","NAME":"David","AGE":"27","ADDRESS":"Texas","SALARY":"85000.0"}{"ID":"6","NAME":"Kim","AGE":"22","ADDRESS":"South-Hall","SALARY":"45000.0"}

但我在（将每一行换行），

{"ID":"1","NAME":"Paul","AGE":"32","ADDRESS":"California","SALARY":"20000.0"}
{"ID":"2","NAME":"Allen","AGE":"25","ADDRESS":"Texas","SALARY":"15000.0"}
{"ID":"3","NAME":"Teddy","AGE":"23","ADDRESS":"Norway","SALARY":"20000.0"}
{"ID":"4","NAME":"Mark","AGE":"25","ADDRESS":"Rich-Mond ","SALARY":"65000.0"}
{"ID":"5","NAME":"David","AGE":"27","ADDRESS":"Texas","SALARY":"85000.0"}
{"ID":"6","NAME":"Kim","AGE":"22","ADDRESS":"South-Hall","SALARY":"45000.0"}

可能吗？

Answer 1

取决于您要做什么。如果您只想 echo 您的 JSON，只需在 echo.

的末尾放一个 <br/>

类似于：

echo json_encode($row) . "<br/>";

或者只用双引号加一个换行符\n。

echo json_encode($row) . "\n";

甚至，用 <p></p>

把它变成一个段落

echo "<p>" . json_encode($row) . "</p>";
