Now, imagine that you have a table of users and a table of interests, with a many to many relationship, and wanted to show all users who had over x amount of matching interests. How would you do it? Do you run a cron job that evaluates each user with each of the others and stores a match score between the two user This sounds like it will create an absurd amount of data as the site grows , or is there a mySQL query that can do such a thing as returning the top x amount of people who have the most shared interests?

You’re probably looking at implementing a fair amount of Graph Theory to your site, and potentially switching to, or using a graph database in tandem with your MySql instance.

The main purpose of NN is that you can avoid using or generating large amount of data big data by made a machine learning.

The only thing that would be living in the session – I imagine – would be some sort of user identifier. Using that identifier you would build the query. I also might consider doing this on the fly as suggested above and use a limit to only return top 10 or whatever. Maybe consider using location as another ranking criteria. Oh I thought you meant storing all the criteria as session variables.

Okay well why not pick a handful of criteria at random to match against at a time, limiting to x number of matches.

Drop me a line if you think I can help you with something, or with suggestions or corrections to this document. PHP is a complex language that has suffered years of twists, bends, stretches, and hacks. The problem is that out of five tutorials, you have a good chance of finding five totally different ways of doing something. Do any of the other ways have subtle bugs or gotchas? This document tries to address that. If a low-level task has multiple and confusing approaches in PHP, it belongs here.

Examples should get you up and running in a basic setting, and you should do your own research to flesh them out into something useful to you. It points to what we consider the state-of-the-art of PHP. This document is not a PHP tutorial. You should learn the basics and syntax of the language elsewhere. In particular, you should carefully review any solution proposed here before implementing it. Your code, and your copy and paste, is your own fault. In particular, high-load web apps might benefit from more esoteric solutions to some of these problems.

Accessors and mutators allow you to format Eloquent attribute values when you retrieve or set them on model instances. For example, you may want to use the Laravel encrypter to encrypt a value while it is stored in the database, and then automatically decrypt the attribute when you access it on an Eloquent model. In addition to custom accessors and mutators, Eloquent can also automatically cast date fields to Carbon instances or even cast text fields to JSON.

To define an accessor, create a getFooAttribute method on your model where Foo is the “studly” cased name of the column you wish to access. As you can see, the original value of the column is passed to the accessor, allowing you to manipulate and return the value. To define a mutator, define a setFooAttribute method on your model where Foo is the “studly” cased name of the column you wish to access.

In this example, the setFirstNameAttribute function will be called with the value Sally. The date’s value will be correctly converted and stored in your database:. By default, timestamps are formatted as ‘Y-m-d H:i:s’. This property determines how date attributes are stored in the database:. When casting to decimal , you must define the number of digits decimal In addition, you should never define a cast or an attribute that has the same name as a relationship.
