blocks|key|1907729|text|在我看来，这有点像一个“典型的”Prolog问题……这是一种与PHP完全不同的编程语言。但也许你可以和波本一起工作。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1907730|或者定义一个包含id、predicate、atom1、atom2列的SQL表来存储"Mary+has+Green+Eyes“的真实性:+predicate+=+"has"，atom1+=+"Mary"，atom2+=+"Green+Eyes”。|1907731|现在，您可以使用您选择的SQL连接和过滤谓词和属性。|1907732|entityMap|0|LINK|mutability|MUTABLE|url|http://en.wikipedia.org/wiki/Prolog^0|G|6|0|0|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@$A|Q|B|R|1|S]]|C|$]]|$1|D|3|E|5|6|7|T|8|@]|9|@]|C|$]]|$1|F|3|G|5|6|7|U|8|@]|9|@]|C|$]]|$1|H|3|-4|5|6|7|V|8|@]|9|@]|C|$]]]|I|$J|$5|K|L|M|C|$N|O]]]]

Sounds to me a little bit like a "typical" <a href="http://en.wikipedia.org/wiki/Prolog" rel="nofollow noreferrer">Prolog</a> problem... which is a quite different programming language than PHP. But perhaps you could work with popen.

Or you define an SQL table with columns [ id, predicate, atom1, atom2 ], to store the truthness of "Mary has Green Eyes": predicate = "has", atom1 = "Mary", atom2 = "Green Eyes".

Now you could join and filter the predicates and attributes with the SQL of your choice.

It looks like a semantic web problem. So you have to figure out how you can use PHP and the semantic web together. Maybe this link <a href="http://bnode.org/blog/2009/05/25/back-from-new-york-semantic-web-for-php-developers-trip" rel="nofollow noreferrer">http://bnode.org/blog/2009/05/25/back-from-new-york-semantic-web-for-php-developers-trip</a> can help?

blocks|key|1220082|text|听起来你应该这样做：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1220083|1)编写一个图形对象，它可以让你以你想要的方式查询数据。|1220084|2)为你的对象写一个持久层|1220085|3)优化在图形对象中执行查询的调用，以便在适当的时候使用数据库调用(例如，如果您需要节省内存)。|1220086|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|L|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|M|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

It kind of sounds like you should approach it this way:

1) Code a graph object that will let you query your data the way you want.

2) Write a persistence layer for your object

3) optimize the calls that do your query's in the graph object to use database calls when appropriate (for example, if you need to conserve memory).

blocks|key|473481|text|我的建议是选择一个基于Java的图形DB，比如OrientDB或neo4j，然后通过PHP/Java+bridge使用它。在不久的将来，neo4j+(以及OrientDB+)应该会得到原生php的支持，你可以用原生访问来代替桥。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|473482|entityMap|0|LINK|mutability|MUTABLE|url|http://php-java-bridge.sourceforge.net/pjb/^0|16|F|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

My suggestion is to pick a Java-based graph DB like OrientDB or neo4j and then use it via the <a href="http://php-java-bridge.sourceforge.net/pjb/" rel="nofollow">PHP/Java bridge</a>. In the near future neo4j (and at some point OrientDB as well) should get native php support and you can replace the bridge with native access.

blocks|key|473502|text|也可以看看这篇关于在PHP中使用OrientDB的文章：http://www.odino.org/346/orientdb-the-graph-db-for-the-web|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|473503|entityMap|0|LINK|mutability|MUTABLE|url|http://www.odino.org/346/orientdb-the-graph-db-for-the-web^0|S|1M|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

Take also a look to this article about the usage of OrientDB with PHP: <a href="http://www.odino.org/346/orientdb-the-graph-db-for-the-web" rel="nofollow">http://www.odino.org/346/orientdb-the-graph-db-for-the-web</a>

blocks|key|3315950|text|考虑到这个问题已经存在一年了，注意到您可以对支持sparql或类似语言的每个rdf数据存储执行这样的查询，这可能仍然很有趣。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3315951|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

well taking into account this question is one year old, it might still be interesting to note that you can do such a query with every rdf datastore that supports sparql or comparable languages.

blocks|key|1908011|text|您还可以找到php的Rexster客户端：https://github.com/PommeVerte/rexpro-php|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1908012|作为额外的信息。Rexster可以从各种其他图形数据库加载图形，如Neo4j和OrientDb等。|1908013|entityMap|0|LINK|mutability|MUTABLE|url|https://github.com/PommeVerte/rexpro-php^0|L|14|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@$A|O|B|P|1|Q]]|C|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@]|C|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]]]

You can also find a Rexster client for php : <a href="https://github.com/PommeVerte/rexpro-php" rel="nofollow">https://github.com/PommeVerte/rexpro-php</a>

As extra information. Rexster can load graphs from various other graph dbs such as Neo4j and OrientDb among others.

I want to use a graph database using php. Can you point out some resources on where to get started? Is there any example code / tutorial out there? Or are there any other methods of storing data that relate to each other in totally random/abstract situations? 

-

Very abstract example of the relations needed: John relates to Mary, both relate to School, John is Tall, Mary is Short, John has Blue Eyes, Mary has Green Eyes, query I want is which people are related to 'Short people that have Green Eyes and go to School' -> answer John

-

Another example: 

<pre><code> TrackA -&gt; ArtistA
 -&gt; ArtistB

 -&gt; AlbumA -----&gt; [ label ]
 -&gt; AlbumB -----&gt; [ A ]

 -&gt; TrackA:Remix
 -&gt; Genre:House

 -&gt; [ Album ] -----&gt; [ label ]
 TrackB -&gt; [ C ] [ B ]
</code></pre>

Example queries: 

Which Genre is TrackB closer to? answer: House - because it's related to Album C, which is related to TrackA and is related to Genre:House

Get all Genre:House related albums of Label A : result: AlbumA, AlbumB - because they both have TrackA which is related to Genre:House

-

It is possible in MySQL but it would require a fixed set of attributes/columns for each item and a complex non-flexible query, instead I need every attribute to be an item by itself and instead of 'belonging' to something, to be 'related' to something.
