mysql数据库中的序列化数据需要组合成一个数组

问题描述

我正在使用PHP/MySQL.

I am working in PHP/MySQL.

我的数据库中有一个名为hourly的表，该表中有一个名为webaddress的列，它们已被序列化.每个网址的每一行都有多行被序列化.

I have a table in my database called hourly in that table their is a column named webaddress these are serialized. There are multiple rows of each column of webaddresses each is serialized.

我需要拉出每一行，将它们解串，然后将它们放入数组中.

I need to pull each row, unserailize them then put them into an array.

我尝试使用这段代码，但是由于PHP函数的限制，它只能捕获1行.

I tried using this bit of code but it only grabs 1 row because of the limitations of the PHP functions.

while ($row = mysql_fetch_array($results)) {$test = unserialize($row[0]);}

我在想像这样的事情可能会起作用:

I was thinking something like this might work:

while(($row = mysql_fetch_array($results)) !== FALSE) {$test[] = $row;}

那行不通...

我该如何抓住每一行，然后将其解串，然后将其添加到数组中?我只需要web_addresses字段中的数据，当前有3行数据.因此，每个web_addresses字段中将有3个序列化的数组，我需要将它们反序列化并组合成另一个数组.希望这更有意义.

How can I grab each row, then unserailize it then add it to an array? I just need the data in the web_addresses field currently there is 3 rows of data. So there would be 3 serialized arrays in each web_addresses field that I need to unserialize and combine into another array. Hopefully that makes more sense.

这是MySQL表:

CREATE TABLE `hourly` (
  `timestamp` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP,
  `id` bigint(20) NOT NULL auto_increment,
  `month` longtext NOT NULL,
  `day` longtext NOT NULL,
  `year` longtext NOT NULL,
  `source` longtext NOT NULL,
  `web_address` longtext NOT NULL,
  `at_replies` longtext NOT NULL,
  `words` longtext NOT NULL,
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=0 DEFAULT CHARSET=latin1

推荐答案

编辑:现在根据OP的信息反映更新:

Now reflects updates based on info by the OP:

从您的问题开始，听起来每一行都有一个序列化的列，并且该列包含每行三项的序列化数组.所以这应该工作:

From your question it sounds like each row has one serialized column, and that column contains a serialized array of three items per rows. So this should work:

$collection = array();
while ( $row = mysql_fetch_array($results)) {
    $values = unserialize($row[0]);
    # $values has unserialized the data into its own array with 3 items

    $collection = array_merge($collection, $values);
}

如果有3个数据库行，并且每个字段都有一个包含3个项目的序列化数组，则$ collection现在将包含一个包含9个项目的数组.

If there were three db rows, and each field had a serialized array with three items, $collection now contains an array with 9 items.
