將PHP數組中的值作為參數傳遞給UNION查詢

Question

我想將數組中的值作為單個參數傳遞給查詢，並按以下方式使用它們

Array
(
    [0] => some
    [1] => text
)

我想要這種功能

public function getData($some,$text)
{
$sql = " select * from table where field1 = '{$some}' OR field3 = {$some}      ";
$union = " UNION ";
$sql = " select * from table where field2 = '{$text}' or field4 = {$text}  ";
}

注意：數組的索引編號可能為N。

Answer 1

您可以使用以下內容：

public function getQuery($dataArray) {
    $queryArray = array();
    foreach($dataArray as $data) {
        $query = "SELECT * from `table`";
        $conditionArray = array();
        foreach($data as $key => $value) {
            $conditionArray[] = "`$key` = `$value`";
        }
        if (!empty ($conditionArray)) {
            $query .= " WHERE ". implode(" OR ", $conditionArray);
        }
        $queryArray[] = $query;
    }
    return implode(" UNION ", $queryArray);
}

Answer 2

由於您的查詢是在同一列上進行的，因此請嘗試使用IN運算符跳過UNIONS：

select * from table where field1 IN (val1,val2....)

然后，您可以將數組作為參數傳遞

public function getData($data)
{
    if(!empty($data)) {
        return " select * from table where field1 = ".implode(",",$data);
    }
}
