Question

很抱歉可能会提出一个基本问题，但我正在停电。

如果我有一个数组数组：

Array
(
    [appsversion] => Array
        (
            [0] => appsversion='6.1.0.33'
            [1] => appsversion='6.1.0.40'
        ),
    [osversion] => Array
        (
            [0] => osversion='6.1.0.53'
            [1] => osversion='6.1.0.42'
        )
)

如何构建一个包含 OR 和 AND 的SQL条件？

即。对于类似的事情：

    $condition = '';
    foreach ($CONDITIONS as $key => $value) {
        # XXX I'm so lost here XXX
    }

    $sql = sprintf('select %s from mytable where %s', $condition);
    $sth = $pg->prepare($sql);
    $sth->execute();

我需要构造的字符串

    (appsversion='6.1.0.33' OR appsversion='6.1.0.40') AND
    (osversion='6.1.0.53' OR osversion='6.1.0.42')

或：

    appsversion in ('6.1.0.33', '6.1.0.40') AND
    osversion in ('6.1.0.53', '6.1.0.42')

请给我一些提示 - 让我的大脑重新开始： - ）

Answer 1

有：

$where = array();
foreach ($conditions as $values) {
    $where[] = '('.implode(' OR ', $values).')';
}
$string = implode(' AND ', $where);

收率：

(appsversion='6.1.0.33' OR appsversion='6.1.0.40') AND (osversion='6.1.0.53' OR osversion='6.1.0.42')

Answer 2

你的意思是这样的吗？

$condition = "(appsversion = '" . implode("' OR appsversion = '", $conditions['appsversion']) . "')";
$condition .= " AND (osversion = '" . implode("' OR osversion = '", $conditions['osversion']) . "')";

或者，用IN清洁：

$condition = "appsversion IN ('" . implode("', '", $conditions['appsversion']) . "')";
$condition .= " AND osversion IN ('" . implode("', '", $conditions['osversion']) . "')";

Answer 3

如果您的原始数组没有复制键名并提供“按原样”的值（我在某种程度上误读了您的问题，但可能它很有用）：

$conditions = array(
    'appsversion' => Array('6.1.0.33', '6.1.0.40'),
    'osversion' => Array('6.1.0.53', '6.1.0.42'),
);

foreach ($conditions as $key => &$values) {
    foreach($values as &$value)
        $value = sprintf("%s='%s'", $key, $value);
    $values = sprintf("(%s)", implode(' OR ', $values));
}
unset($values, $value);
echo implode(" AND \n", $conditions);

输出/ Demo：

（appsversion ='6.1.0.33'ODsversion ='6.1.0.40'）AND （osversion ='6.1.0.53'OR osversion ='6.1.0.42'）

Answer 4

$conditions1 = array();
foreach ($CONDITIONS['appsversion'] as $value) {
    $conditions1[] = sprintf("appversion = '%s'", mysql_real_escape_string($value));
}

$conditions2 = array();
foreach ($CONDITIONS['osversion'] as $value) {
    $conditions1[] = sprintf("osversion = '%s'", mysql_real_escape_string($value));
}

$sql = sprintf('select %s from mytable where (%s) AND (%s)', $cols, implode(' OR ', $conditions1), implode(' OR ', $conditions2));
$sth = $pg->prepare($sql);
$sth->execute();

Answer 5

foreach($C as $key => $value)
{
    $str .= ($str ? ' AND ' : '') . '(' . implode(' OR ',$value) . ')';
}
