我有一些MySQL查询,但其中一个不起作用(“Number 1”)。另一个查询(“数字2”)工作正常。但我必须多次重复“2号”,超过100个。这很难。我没有得到查询“1号”工作。怎么了?
“1号”
<?php
require_once ("../config/config.db.inc.php");
$sdd_db_host = DB_HOSTNAME;
$sdd_db_name = DB_DATABASE;
$sdd_db_user = DB_USERNAME;
$sdd_db_pass = DB_PASSWORD;
mysql_connect($sdd_db_host,$sdd_db_user,$sdd_db_pass);
mysql_select_db($sdd_db_name);
mysql_query ("set_client='utf8'");
mysql_query ("set character_set_results='utf8'");
mysql_query ("set collation_connection='utf8_general_ci'");
mysql_query ("SET NAMES utf8");
$menu = mysql_fetch_array(mysql_query("SELECT * `tbl_customers`"));
echo $menu['finskaya_razdel']; ?>
什么都没发生,但它应该! ['finskaya_razdel']不仅仅是一个......
“2号”
<?php
require_once ("../config/config.db.inc.php");
$sdd_db_host = DB_HOSTNAME;
$sdd_db_name = DB_DATABASE;
$sdd_db_user = DB_USERNAME;
$sdd_db_pass = DB_PASSWORD;
mysql_connect($sdd_db_host,$sdd_db_user,$sdd_db_pass);
mysql_select_db($sdd_db_name);
mysql_query ("set_client='utf8'");
mysql_query ("set character_set_results='utf8'");
mysql_query ("set collation_connection='utf8_general_ci'");
mysql_query ("SET NAMES utf8");
$menu = mysql_query("SELECT finskaya_razdel FROM `tbl_customers` WHERE customers_id='1008' or customers_id='8'");
$menu_res = mysql_result($menu, 0);
echo $menu_res; ?>
此查询有效。但它很疯狂......我有超过100个查询要做。数字1更“华丽”。我做错了什么?
答案 0 :(得分:1)
msql_fetch_*
一次提取一行。你必须每次循环并应用它。mysql_fetch_assoc
(使用mysql_fetch_array
,您必须使用索引号。)因此...
$menu = mysql_query("SELECT * FROM tbl_customers");
while ($row = mysql_fetch_assoc($menu))
echo $row["finskaya_razdel"];
...或者如果你需要在php多维数组中得到结果......
$menu = mysql_query("SELECT * FROM tbl_customers");
$results = array();
while ($row = mysql_fetch_assoc($menu))
$results[] = $row;
注意 :@BarclickFloresVelasquez是对的。你应该转移到mysqli或PDO
