This article mainly introduces the method of obtaining data in the database in PHP. Interested friends can refer to it. I hope it will be helpful to everyone.
No more nonsense, just go to the code
<?php header("Content-type:text/html;charset=utf-8");//字符编码设置 $servername = "localhost"; $username = "root"; $password = "root"; $dbname = "web"; // 创建连接 $con =mysqli_connect($servername, $username, $password, $dbname); // 检测连接 $sql = "SELECT * FROM users"; $result = mysqli_query($con,$sql); if (!$result) { printf("Error: %s\n", mysqli_error($con)); exit(); } $jarr = array(); while ($rows=mysqli_fetch_array($result,MYSQL_ASSOC)){ $count=count($rows);//不能在循环语句中,由于每次删除 row数组长度都减小 for($i=0;$i<$count;$i++){ unset($rows[$i]);//删除冗余数据 } array_push($jarr,$rows); } echo $str=json_encode($jarr);//将数组进行json编码 ?>
This is after getting it Convert to json format
