Question

...
$count=1;
while ($row = mysql_fetch_array($result)){
    $result1 = mysql_query("SELECT something from something where name like %$row['name']% ");
    while ($data = mysql_fetch_array($result1)){
        echo $data[title];
        echo $count;
    }
    $count++
}

如何增加这样的联合号码？第一个foreach结果进行第二次查询。然后计算来自2ed foreach的所有结果。我的代码导致了

title1 1
title2 1
title3 2
title4 2
title5 2
title6 3

如何制作

title1 1
title2 2
title3 3
title4 4
title5 5
title6 6

感谢。

Answer 1

 while ($data = mysql_fetch_array($result1)){
    echo $data[title];
    echo $count;
    $count++;
  }

基本上将$count++放在嵌套的

中

Answer 2

如果您不想为每个$行重置$ count，则代码必须如此。

$count=1;
while ($row = mysql_fetch_array($result)){
    $result1 = mysql_query("SELECT something from something where name like %$row['name']% ");
    while ($data = mysql_fetch_array($result1)){
        echo $data[title];
        echo $count++;
    }
}

，否则;

while ($row = mysql_fetch_array($result)){
    $count=1;
    $result1 = mysql_query("SELECT something from something where name like %$row['name']% ");
    while ($data = mysql_fetch_array($result1)){
        echo $data[title];
        echo $count++;
    }
}
