php?数据库查询

[qq_20610429]

 $id=array(23,24);
 $sql =" select `series_title` FROM ca_series where id in $id";
//我想查id在23,24里的内容

echo $sql;
输出的效果:select `series_title` FROM ca_series where id in Array

想要的效果:select `series_title` FROM ca_series where id in (23,24);

你只是查的整个数组吧，并没有具体数组里的某个值。

$id = array(23,24); $in = join(',', $id); $sql = "select `series_title` FROM ca_series where id in ($in)";
