如何 return 此 SQL 中的所有行同时
How to return all the rows in this SQL while
问题太广泛了,我在论坛上没有找到答案,或者至少没有找到答案。习惯用数组,长篇大论觉得不实用运行,决定把自己放在编程对象里
这是我的问题:当我 运行 下面的 SQL 查询时,我无法恢复所有我应该恢复的行。而且我不知道该怎么做...
public function testing($param) {
$return = new stdClass();
if ($request = $this->getConnexion()->prepare('SELECT col1, col2, col3 FROM table WHERE col1=?') or die(mysqli_error($this->getConnexion()))) {
$request->bind_param('s', $param);
$request->execute();
$request->bind_result($col1, $col2, $col3);
$request->store_result();
while($request->fetch()) {
$return->col1 = $col1;
$return->col2 = $col2;
$return->col3 = $col3;
/*
Here's what I used to do before
$return[] = array(
'col1' => $col1,
'col2' => $col2,
'col3' => $col3
);
*/
}
$request-> close();
// Here : how to make it understand that I want all the lines and not a single
return $return;
} else {
return false;
}
}
好吧 $return
是您的 stdClass 对象,因此您只是在每次迭代时覆盖 3 个属性。使用对象数组:
$return = array();
...
...
while($request->fetch()) {
$item = new stdClass;
$item->col1 = $col1;
$item->col2 = $col2;
$item->col3 = $col3;
$return[] = $item;
}
