优化foreach中的while和SQL
我的代码:
$text = '12-name-y-86';
$array = explode('-',$text);
foreach($array as $value) {
$sql = mysql_query("SELECT * FROM `table` WHERE `pid`='$value' ORDER BY `id` LIMIT 3");
echo '***'.$value.'***';
echo '<br />';
while($row = mysql_fetch_array($sql)) {
echo $row['title'];
echo '<br />';
}
echo '<br /><br />';
}
打印:
12
标题1
标题2
标题3
姓名
ti1
ti2
ti3
是
t1
t2
tle3
86
mytitle1
mytitle2
mytitle3
此代码可以完全购买 $text 中的更多值,服务器已关闭!
This code work full buy for more values in $text , server has down !
推荐答案
尝试在一个查询中选择所有记录,如下所示:
Try to select all records in just one query, like this:
$text = '12-name-y-86';
$array = explode('-', $text);
$array = "'" . implode(',', $array) . "'";
$sql = mysql_query("SELECT * FROM `table` WHERE `pid` IN (' . $array . ') ORDER BY `id` LIMIT 3");
while($row = mysql_fetch_array($sql)) {
echo $row['title'];
echo '<br />';
}
echo '<br /><br />';
