Question

我正在通过mysqli查询从表中获取数据。我能够成功检索数据。但是我不知道这是什么问题，当我json_encode()提取数据时。然后它不会发送回数据，但是当我print_r()提取数据时，它就会显示出来。我正在使用ajax发送请求，作为响应，我可以成功获取print_r()数据，但编码时无法获取。

PHP代码

//The Actuall query
$sql = "SELECT `companies_jobs`.*, `companies`.`name`, `companies`.`location`, `companies`.`image` FROM `companies`, `companies_jobs` WHERE `companies_jobs`.`comp_fk` = `companies`.`id`";

show($sql, $db_conn);


public
function show($sql, $db_conn) {
  $data = array();
  if ($db_conn - > query($sql)) {
    $r = $db_conn - > query($sql);
    if ($r - > num_rows > 0) {
      for ($i = 0; $i < $r - > num_rows; $i++) {
        $data[] = $r - > fetch_assoc();
      }
      //echo json_encode($data);
      print_r($data);
    }
  } else {
    echo $db_conn - > error;
  }
}

我从print_r()获得的结果

Answer 1

输出Aprendiz do Senai - 2� Semestre 20中有特殊字符，这就是其中断的原因。尝试在数据库连接中传递UTF8字符集。

“ JSON_ENCODE（）”不适用于获取的数据-PHP
