我正在尝试迭代MySQL对象并在另一个页面上使用ajax调用来追加数据,但是我无法让php将有效的JSON返回给回调。
这显然不起作用......
<?php
$db_host = "localhost";
$db_user = "blah";
$db_pass = "blah";
$db_name = "chat";
$mysqli = new MySQLi($db_host, $db_user, $db_pass, $db_name);
$myQuery = "SELECT * FROM users";
$result = $mysqli->query($myQuery) or die($mysqli->error);
$row = $result->fetch_assoc();
echo json_encode($row);
?>
或者这个......
<?php
$db_host = "localhost";
$db_user = "blah";
$db_pass = "blah";
$db_name = "chat";
$mysqli = new MySQLi($db_host, $db_user, $db_pass, $db_name);
$myQuery = "SELECT * FROM users";
$result = $mysqli->query($myQuery) or die($mysqli->error);
while ( $row = $result->fetch_assoc() ){
echo json_encode($row) . ", ";
}
?>

$data = array();
while ( $row = $result->fetch_assoc() ){
$data[] = json_encode($row);
}
echo json_encode( $data );
这应该这样做。此外,您可以使用http://jsonlint.com/查看JSON输出的问题。
使用fetch_all()
更新也可能是一个好主意
$data = $result->fetch_all( MYSQLI_ASSOC );
echo json_encode( $data );

我用这个:
$json = array();
if(mysqli_num_rows($result)){
while($row=mysqli_fetch_assoc($result)){
$json[]=$row;
}
}
mysqli_close($mysqli);
echo json_encode($json);
?>
我得到这样的东西
[ { “ID”: “2”, “usuario”: “zeldafranco”, “密码”: “笑”},{ “ID”: “3”, “usuario”: “弗朗”, “密码”: “弗朗” },{ “ID”: “4”, “usuario”: “peteko”, “密码”: “sanpeteko”},{ “ID”: “5”, “usuario”: “prueba”, “密码”:” prueba “},{” ID “:” 6" , “usuario”: “测试”, “密码”: “测试”}, { “ID”: “7”, “usuario”: “pibe”, “密码”: “HOLA”}, {“id”:“8”,“usuario”:“que ase”,“password”:“que ase”},{“id”:“9”,“usuario”:“trt”,“password”:“ TRT“}, { “ID”: “10”, “usuario”: “TYT”, “密码”: “TYT”} ]

$arrUsers = array();
$fetch = mysql_query("SELECT * FROM users");
while ($row = mysql_fetch_array($fetch, MYSQL_ASSOC)) {
$arrUsers['id'] = $row['name'];
$arrUsers['col1'] = $row['col1'];
$arrUsers['col2'] = $row['col2'];
array_push($arrUsers,$row_array);
}
echo json_encode($arrUsers);
