Portable UTF-8 v 1.3 released
Version 1.3 of Portable UTF-8 library has been released. This version extends the functionality by adding 20 string handling and utility functions to the api. There are a few bug fixes and lots of optimizations and improvements.
All-in-One Wrapper for APC, EAccelerator, xCache and Disk Cache
This library lists apc_* family of functions for eAccelerator, xCache or Disk Cache operations if APC or APCu is not available on server. When APC is installed and enabled, this library does nothing (because the desired functions are already available) – resulting in zero wrapper call overhead since all calls go directly to internal APC api.
Checking Multidimensional Arrays in PHP
When working with arrays in PHP, you may often need to check whether each of an array’s element contains scalar data or is there an element that contains another array (a sub-array). In other words, what you want is to check if the array multidimensional? To solve the mystery, many people quote a buggy snippet on stackoverflow and other programming websites. Reading through such pages, I decided to explain a bug in the most commonly used method of checking multidimensional arrays, and also to provide the right solution.
Portable UTF-8 v 1.2 released
I have just uploaded the next version of the Portable UTF-8, PHP unicode library. This version adds 9 UTF-8 string functions to the library. There are a few bug fixes, and also some performance optimizations, but the release was mainly to extend the functionality of the library.
Best Online Code Sharing Tools
Here is the list of many popular code sharing tools. Many of these have pretty code highlighting facility for popular programming languages. Few even allow embedding code into websites.
dir_callback – Lets play with Directories (PHP)
PHP provides some handy functions for file and directory handling, but to deal with nested directories, it does not provide much. There are basic directory functions and a directory iterator, but does not cover directory level operations like moving, cloning, counting files, deleting etc.
Portable UTF-8: Demo
In this post I will demonstrate the working of utf8_* family of functions that belong to Portable UTF-8 Library.
Portable UTF-8 – A Lightweight Library for Unicode Handling in PHP
Portable UTF-8 library is a Unicode aware alternative to PHP’s native string handling API. It is written in PHP and can work without mbstring, iconv, UTF-8 support in PCRE, or any other library. The benefit of Portable UTF-8 is that it is very light-weight, fast, easy to use, easy to bundle, and it always works (no dependencies).
Interesting Use of PHP Super Globals
When the php.ini directive auto_globals_jit is enabled, $_SERVER and $_ENV super global arrays are created at the time they are first used in the script, rather than being initialized at the start of script. The benefit of this directive is that these super global arrays are not created at all if not used within a script, resulting in a little performance gain.
