我已经保存了输出后续行的参数化字符串匹配查询所需的步骤。我在转移到一个有故障的驱动器时丢失了文件。所以…我试着把东西混在一起，但这行不通。
$stmt = $link->prepare("SELECT id,entry,date from table WHERE string=? ORDER by Id DESC");
$stmt->bind_param('s',$string);
$stmt->execute();
$stmt->bind_result($id_db,$entry_db,$date_db);
if (($result = $link->query($stmt)) {
while ($row = $result->fetch_row()){
}
}
我已经可以告诉这是错误的，我不使用参数化的结果，我试图使用数组索引，如$row[0]。
我知道这个会被骂的。
我想要的最终结果是:例如:
string1有行:bob, mack, ChrisString2有行:alice, claire, lara
如果$string=string1，那么输出应该是:
克里斯麦克鲍勃
我认为我的问题是我混合语句类型
假设"$link"是PHP的"mysqli"类的一个实例，并且"id"answers"id"是表中的两个不同的列(如果不是这种情况，请尝试将"id"替换为"id"段中的".. "。ORDER BY Id..")，根据您的示例，我建议您尝试以下操作:
// Declare your "prepare" statement (make sure to change "Id" for "id" if both are used
// in reference to the same column in your table)
$stmt = $link->prepare('SELECT id, entry, date FROM table WHERE string = ? ORDER BY Id DESC');
// Bind the $string variable
$stmt->bind_param('s',$string);
// Execute the statement
$stmt->execute();
// Store the result (this is sometimes useful, depending on the data types in your table)
$stmt->store_result();
// Check whether at least one row in table matches the query, if not, stop here...
if ($stmt->num_rows === 0) exit('No matching rows'); // or do something else...
// Declare a container (i.e. storage) for each row (this is optional and depends on what
// you are trying to achieve)
$data = [];
// Loop through results (this is just an example; this could be achieved in a number
// of different ways)
for ($i = 0; $i < $stmt->num_rows; $i++)
{
// Add a new array cell to $data, at index $i
$data[$i] = [];
// Bind result for row $i
$stmt->bind_result($data[$i]['id'],$data[$i]['entry'],$data[$i]['date']);
// Fetch $i^{th} row
$stmt->fetch();
}
// Check if it worked (temporary)
var_dump($data);
