示例一:
原因:第二行前面不能有空格;
解决:去掉空格就可以了;
示例二:
<?php
require 'conn.php'; //连接数据库
$sql="SELECT * FROM Downloads";
$result = mysqli_query($sql,$link);
if(mysqli_num_rows($result)){
while($row=mysqli_fetch_assoc($result)){
$data[] = array(
'id' => $row['id'],
'file' => $row['filename'],
'downloads'=> $row['downloads']
);
}
echo json_encode($data);
}
?>
报错:
解决方法:把$result = mysqli_query($sql,$link); 换成$result = mysqli_query($link,$sql); 就可以了;
