<body>
<p>This is a simple class for reading files from the end,like Unix 'tail' command.But 
  with some limitations!You can get only the last line<br />
  There are many implementations like this,but this use less memory,than others,i 
  hope... </p>
<p><font size="2" color="#990033">How you can use it?</font> </p>
<p>An example:<br />
  <br />

<pre><font color="#0066FF">&lt;?

 //
 // tail-usage.php

 //
 require_once("shagaTail.php");
 $myShaga = new shagaTail;
 $myShaga->tailFile = 'filename.log'; //setting the filename
 for(;;){
 	$line = $myShaga->getStr();
 	// Analize the line or just print it
 	echo $line."<br />\n";
 	$myShaga->update(); // if the tailed file file is updated,tail it again
 }
