PHP MYSQL在获取时获取数组编号

Question

Following a query, a mysql_fetch_array generates an array of results that have a sequential number in them that you can get, I believe, by putting [] at the end of the field.

While fetching I want to set sequential ids for divs as in <div id="row1"> to keep track of the rows being returned. Row is just a word, not a variable. Is there an easy way to append a number to row based on the array number--something like row[] without having to set up a counter? Thanks.

Answer 1

if you don't want to set up a counter which i don't understand why, and if you have something like id as table row (your primary key) that is being fetched from the database then you can do it like this.

while($row = mysql_fetch_array($res)) { 
    echo '<div id="row'.row['id'].'"> Row '.$row['id'].' text</div>';
}
