php - 具有从数组中获取的多个条件的 PHP PDO 查询

Question

我有几个条件要在单个查询中完成。基本查询：

$query = "select * from table1
    inner join 
        table2 on table1.id=table2.id
    where 
        ".$condition."
    limit 0,100;";

我有要查询的值数组：

$Var = array(
    1 => array('name' => 'somename1','value' => 'somevalue1'),
    2 => array('name' => 'somename2','value' => 'somevalue2'),
    3 => array('name' => 'somename3','value' => 'somevalue3'),
    4 => array('name' => 'somename4','value' => 'somevalue4')
)

现在在循环中

foreach($Var as $Array){  
    $condition .= '(T1_column1 = '.$Array['name'].' and T2_column1 = '.$Array['value'].') or ';
}

最后结果：

$query = "select * from table1
    inner join 
        table2 on table1.id=table2.id
    where 
        (T1_column1 = somename1 and T2_column1 = somevalue1) or  
        (T1_column1 = somename2 and T2_column1 = somevalue2) or  
        (T1_column1 = somename3 and T2_column1 = somevalue3) or  
        (T1_column1 = somename4 and T2_column1 = somevalue4)
    limit 0,100;";

有没有办法使用 PDO 做同样的事情：prepare,bindvalue,execute ？或 foreach 循环中的 bindValue 具有相同的效果？我怎样才能做到这一点？

Answer 1

这是PDO 的重复绑定未知数量的参数？

为方便起见，这是 Paystey 的答案中修改后的代码以适合您的示例：

$sql = 'SELECT * FROM table1
    INNER JOIN table2 ON table1.id=table2.id
    WHERE ';
foreach($Var as $Array)
{
    $sql .= '(T1_column1 = ? and T2_column1 = ?) or ';
    $binds[] = $Array['name'];
    $binds[] = $Array['value'];
}
$prep = $db->prepare(substr($sql,0,-3) . 'limit 0,100');
$i = 0;
foreach($binds as $bind){
   $prep->bindValue(++$i, $bind);
}
$prep->execute();
