我有一个返回一些结果的查询,然后我使用一个while循环来输出结果。
我遇到的问题是,我想在while循环之前返回“问题”,这样它就不会在循环中多次显示。
我有以下代码:
$query = "SELECT * FROM polls LEFT JOIN pollanswers ON polls.pollID = pollanswers.pollID WHERE polls.pollID = 1 ORDER By pollAnswerListing ASC";
$result = mysql_query($query);
echo '<p>Question&
我使用嵌套的while循环从两个不同的表中检索信息(学生,这两个表都是通过主键“id”链接的年级)。
我希望它以以下格式输出:
Student ID "123"
- Grade 1 for ID "123"
- Grade 2 for ID "123"
Student ID "555"
- Grade 1 for ID "555"
- Grade 2 for ID "555"
Student ID "666"
- Grade 1 for ID "666
我通过while循环从mysql数据库中获取记录。
$sql=mysql_query("SELECT * FROM animate ORDER BY RAND() LIMIT 10") or die("query Field");
while($row=mysql_fetch_array($sql)){
$row['code'];
}
输出为xyacefg。
现在,我想将这个输出分解成一个数组,我想将每个字母放入单独的数组索引中,如
数组(‘x’,'y','a','c','e
我尝试了大约两个小时的json_encoding,但我没有得到所需的输出。实际上,这是对移动应用程序开发人员的要求,我将在下面解释here.The代码的格式,这是我尝试过的:
include_once("class_connection.php");
//Getting the Parent Category
$sqlStr = mysql_query("select catname , id from `category` where `parentid`='0'");
$jsonArray = array();
while ($fetc
我对Mysql查询有问题。我写了这段代码
enter code here
$result = mysql_query("SELECT * FROM description");
while ($row = mysql_fetch_array($result)){
$data[] = $row;
foreach ($data as $row){
echo $row['name'];
}
}
enter
这就是我调用的函数。
function GetSubmissions($coach){
$result = mysql_query("SELECT * FROM `ptable` WHERE coach = '$_SESSION[username]'") or trigger_error(mysql_error());
while($row = mysql_fetch_array($result)){
foreach($row AS $key => $val
下面的代码只输出一行(数据库中有2行应该输出)。
我认为这是id=$dataid中的问题,因为data1是数组而不是单个值。我希望能解决这个问题,但它看起来不太好……
$results1 = mysql_query("SELECT * FROM keywords WHERE keyword='$search' ORDER BY (relevant-irrelevant) DESC");
$data1=mysql_fetch_array($results1);
$results2=mysql_query("SELECT * FROM
你好,我这里有以下php代码:
$username = trim(mysql_real_escape_string($username));
$password = md5(trim(mysql_real_escape_string($password)));
$query = "SELECT user_level FROM user WHERE username='$username' AND password='$password'";
$result = mysql_query($query) or die(
我想让while循环基于匹配的"id“列值输出。
$query = "SELECT s.id,s.last,s.first,s.course1,s.course2,s.course3
,e.id,e.last,e.first,e.course1,e.course2,e.course3
FROM $startsem1 s
JOIN $endsem1 e on s.id = e.id";
$result = mysql_query($query) or die(mysql_error()
我正在创建一个应用程序,其中的结果将以组/批的形式显示
示例输出应为:批次1:显示->数据库中的所有实体批次2:显示->数据库中的所有实体批次3:显示->数据库中的所有实体
$qry = mysql_query("SELECT *,sum(counter) FROM table_name GROUP BY batch") or die("ERROR: ".mysql_error());
if(!empty($qry))
{
while($row = mysq
我有这样的代码:
<?
$kate=mysql_query("select category_id from movies_cat where movie_id='$ids'");
while($cat=mysql_fetch_array($kate)){
$kate2=mysql_query("select name_cat from categories where id='$cat[category_id]'");
$html = array();
while($cat2=
if ($db_found) {
$result = mysql_query("SELECT *,
CAST(AES_DECRYPT(jmeno, 'usa2010') AS CHAR(50)) name,
CAST(AES_DECRYPT(prijmeni, 'usa2010') AS CHAR(50)) lastname,
FROM pacienti WHERE id='13'");
while ($row = mysql_fe
正在尝试转换为MySQLi。这几天我得到了很大的帮助,谢谢。我的下一个问题是如何在使用LEFT JOIN时进行转换。
运行MYSQL代码
$q1 = 'SELECT * FROM earth LEFT JOIN cities ON (cities.countryid4city = earth.countryid) GROUP BY countryid ORDER by countryid';
$q2 = 'SELECT * FROM cities ORDER BY cityname';
$mytable1 = mysql_query($q1);
$mytable
你好,我正在尝试用php中的while循环来做函数,但是不能在这里写,这是我的代码
function mail_detail($mail_detail){
$data= mysql_query("select * from messages where messages.to = '$mail_detail' and to_viewed = 0 ORDER BY messages.id DESC");
while ($result= mysql_fetch_array($data)){
return $result;
}
}
