php - 坐标 2 foreach 循环

Question

我有 2 个 foreach 循环，它们都循环通过同一个数组；然而，一个在使用 str_replace 后循环遍历数组，而另一个不使用 str_replace；

我的问题; 我如何协调这两个循环，以便它们同时循环通过同一个数组？

抱歉，如果我的问题没有描述性；

$contents = ftp_nlist($conn_id, $dir);
$unalteredcontents = ftp_nlist($conn_id, $dir);
foreach ($unalteredcontents as $fname2)
{
    if (($fname2 != '.') && ($fname2 != '..'))
    {
        $url = "http://mywebsite.com/folder/" . $userid . "/" . $fname2 . "";
        next($fname2);
    }
}
$contents = str_replace("-", '', $contents);
$contents = str_replace(".pdf", '', $contents);

foreach ($contents as $fname)
{
    if (($fname != '.') && ($fname != '..'))
    {
        $sql_select = "INSERT INTO `database`.`column` (`data`, `fileurl`) VALUES ('" . $fname . "', '" . $url . "') ";
    }
}

Answer 1

从你的问题不清楚。但我试一试：

$unalteredcontents = ftp_nlist($conn_id, $dir);
foreach ($unalteredcontents as $fname2)
{
    if (($fname2 != '.') && ($fname2 != '..'))
    {
        $url = "http://mywebsite.com/folder/" . $userid . "/" . $fname2 . "";

        $contents = str_replace("-", '', $fname2);
        $contents = str_replace(".pdf", '', $contents);

        $sql_select = "INSERT INTO `database`.`column` (`data`, `fileurl`) VALUES ('" . $contents. "', '" . $url . "') ";
    }
}

Answer 2

像这样的东西：

$unalteredcontents = ftp_nlist($conn_id, $dir);
$contents = str_replace("-", '', $unalteredcontents);
$contents = str_replace(".pdf", '', $contents);

foreach ($contents as $key => $fname)
{
    if (($fname != '.') && ($fname != '..'))
    {
        $url = "http://mywebsite.com/folder/" . $userid . "/" . $unalteredcontents[$key];
        $sql_select = "INSERT INTO `database`.`column` (`data`, `fileurl`) VALUES ('" . $fname . "', '" . $url . "') ";
    }
}
