PHP Namespaces and Yii

takobell · January 31, 2012, 10:29pm

It would be nice to not force the requirement of PHP 5.3 namespaces to map directly to file system paths.

As it is now, the namespace:


segment1\segment2\segment3

needs to maps to the alias:


segment1.segment2.segment3

which maps to a directory path on the file system.

What I currently can’t seem to do is have a namespace that spans multiple directories.

I stumbled upon a similar problem and asked myself: “Wouldn’t this violate the PSR-0”?

PSR-0-final-proposal.md

# PSR-0 Final Proposal (PHP Standards Working Group) #
The following describes the mandatory requirements that must be adhered to for autoloader interoperability.

## Mandatory: ##

 * A fully-qualified namespace and class must have the following structure ` \ <Vendor Name> \ (<Namespace>)*  \ <Class Name> `
 * Each namespace must have a top-level namespace ("Vendor Name").
 * Each namespace can have as many sub-namespaces as it wishes.
 * Each namespace separator is converted to a `DIRECTORY_SEPARATOR` when loading from the file system.
 * Each "\_" character in the CLASS NAME is converted to a `DIRECTORY_SEPARATOR`. The "\_" character has no special meaning in the   namespace.

Does that matter? Yii’s autoloader must support PSR-0 to have the ability to load 3rd party librarys and custom stuff. Also the application structure generated by yiic should follow PSR-0. In addition to that the autoloader itself should follow PSR-0(meaning its physical location) to be loaded from another library (using yii as 3rd party library). But I don’t think that unindependent classes of the core have to follow psr-0 (as long as the autoloader can find them fast). Same goes for applications. They should follow PSR-0 by default. But we should have the option to use our preffered structure.

Haven’t worked with proem, yet. But I’m looking forward to a simliar looking autoloader in Yii2
