我想知道总计数器 共有15个cc_cates。 我想通过一个查询找到整个值。
$result = mysqli_query($connect, "SELECT distinct cc_cate, count(cc_cate)as count FROM cc_text WHERE id='aaaa' group by cc_cate order by cc_cate desc" ) or die("cate");
for ($i = 0; $t = mysqli_fetch_array($result); $i++) { if ($i == $t['count']) $last = "colspan=7"; echo "$i == $t[count] ,"; }
答案 0 :(得分:1)
仍然不清楚,但是按照您在注释中指定的内容,我猜这两个答案之一应该是您要查找的内容:
// if you just want the number of categories
$result = mysqli_query($connect, "SELECT COUNT(distinct cc_cate) as cnt_cat FROM cc_text WHERE id='aaaa'") or die("cate");
$row = mysqli_fetch_assoc($result);
echo "Number of categories = ". $row['cnt_cat'];
// if you want to list all categories and count them all
$result = mysqli_query($connect, "SELECT distinct cc_cate FROM cc_text WHERE id='aaaa'") or die("cate");
$i=0;
while ($row = mysqli_fetch_assoc($result)){
$i++;
echo "Category $i = ". $row['cc_cate'];
}
echo "Total categories = $i";
