<h2>Compress Text Data Using Letter Frequent Information</h2><br />

<span class="FirstChar">T</span>his class compresses text strings into roughly 70% of
their original size by benefit from using compact coding for most frequented
letters in a given language. This algorithm associated with text language, so
you will find 6 different classes for the following languages: Arabic, English,
French, German, Italian and Spanish language.<p> </p>
<p><font color="#006600" size="4" face="Times New Roman, Times, serif"><strong><em>Benefits
of this compress algorithm include:</em></strong></font><br />
<br />
<b><font color="blue">1-</font></b> It is written in pure PHP code, so there is no need to any PHP extensions
to use it. <br />
<b><font color="blue">2-</font></b> You can search in compressed string directly without any need uncompress
text before search in.<br />
<b><font color="blue">3-</font></b> You can get original string length directly without need to uncompress
compressed text.</p>
<p><strong><em><font color="#990000" size="4" face="Times New Roman, Times, serif">Note:</font></em></strong><br />
Unfortunately text compressed using this algorithm lose the structure that
normal zip algorithm used, so benefits from using ZLib functions on this text
will be reduced. </p>
<p>There is another drawback, this algorithm working only on text from a given
language, it does not working fine on binary files like images or PDF.<br />
