问题描述
大家好
我的问题是php

我写了一个代码来做到这一点

这是代码

}
$sql = ('SELECT id as id, filename, link
FROM link
WHERE id =$id');
$result = mysql_query ($sql);
if (!$result) {
echo "Could not successfully run query ($sql) from DB: " . mysql_error();
exit;
}
if (mysql_num_rows($result) == 0) {
echo "No rows found, nothing to print so am exiting";
exit;
}
// While a row of data exists, put that row in $row as an associative array
// Note: If you're expecting just one row, no need to use a loop
// Note: If you put extract($row); inside the following loop, you'll
// then create $userid, $fullname, and $userstatus
while ($row = mysql_fetch_assoc($result)) {
echo $row["id"];
echo $row["filename"];
echo $row["link"];
}
mysql_free_result($result);
?>
