Wrapper library to fix inconsistencies in PHP's core functions

PHP is great and Composer, PHP-FIG, and all the different frameworks make it even greater. However, there is still legacy stuff in the language itself that makes PHP harder to use than it should be (see http://phpsadness.com/ for one of many lists).

Zubr is a wrapper library to fix inconsistencies in PHP's core functions. It wraps PHP's built-in functions and attempts to fix a few things—starting with consistent naming, order of arguments, and more.

For instance, from:




and even:



\Zubr\html_entity_encode() // alias to htmlentities(), \Zubr\html_entities()

Functions always have the same name as the built-in ones, but they follow the same set of rules. Zubr is intuitive to use, because function names are predictable and similar to the ones you're used to.

Zubr's idea came from commenting this HN post: https://news.ycombinator.com/item?id=14883784


0. Introduction

We're ignoring PHP < 7.0.0. Any function that is deprecated and not included in PHP 7.0.0 won't be found in Zubr.

1. Function naming

1.1 Underscores

See: http://phpsadness.com/sad/4

We always use snake_case.

1.2 Prefixes

See: http://phpsadness.com/sad/15

We add aliases using micro instead of u (which sometimes means user).

We add aliases using user instead of u (which sometimes means micro).

1.3 to vs. 2

See: http://phpsadness.com/sad/48

We add aliases using to instead of 2.

2. Order of arguments

2.1 Needle/haystack

See: http://phpsadness.com/sad/9 and similar.

We always put the subject first, then the keyword ($haystack first, then $needle).

For example, you'd say "search Google for dog" (which means "search $subject for $keyword").

Most PHP functions already follow this convention.

2.2 Callbacks

See: http://phpsadness.com/sad/6

We always put the callback last.

3. Argument type

Note: If the parameters given to a function are not what it expects, such as passing an array where a string is expected, the return value of the function is undefined. In this case it will likely return NULL but this is just a convention, and cannot be relied upon. http://php.net/manual/en/functions.internal.php

We'd like to fix the above in > 1.0 releases.


Version 1.0 will contain all of PHP's core built-in functions.

We might then go on to implement a private plugin system to add bundled extensions in 2.0, and make the plugin system public so that anyone can implement wrappers to external extensions in version 3.0.

We have detailed milestones with all features that will be implemented up to version 1.0 at https://github.com/nkkollaw/zubr/milestones.
