Description 

Author

Khaled Al-Shamaa

This package can be used to compress text based on prior knowledge of the frequency of letters of texts in the same idiom.

Currently there are class versions for the idioms: Arabic, English, French, German, Italian and Spanish.

These classes can generate a compressed version of text strings that occupy in average about 70% of the original length.

This class is part of Khaled Al-Shamaa project for PHP and Arabic language:

Winner

Prize: One copy of Delphi for PHP		 Data compression techniques often take advantage of redundancy, i.e. sequences of data that appear repeated.

Text is usually very compressible because it uses the same set of characters in each idiom.

This package takes advantage of that fact to provide PHP classes optimized to compress different idioms, This way it achieves greater efficiency based on the knowledge of the most frequently used letters in each supported idiom.
