Christian Vigh

This class can store values in a circular buffer array.

It can keep adding values to an array with position numbers with up to a given limit.

When the array entries exceed the initial limit number, the class starts setting values from the start of the array.

<?php


    /***********************************************************************************************************





        The following example demonstrates the use of the CircularBuffer class.





        It first creates a circular buffer for handling 10 items, then adds 20 items to it.


        It finally displays the contents of the circular buffer, which contains only items #11 to #20 (the


        items #1 to #10 have been overridden).





     ***********************************************************************************************************/


    require ( 'CircularBuffer.phpclass' ) ;





    if  ( php_sapi_name ( )  !=  'cli' )


        echo ( "<pre>" ) ;





    // Create a circular buffer of 10 elements


    $buffer        =  new CircularBuffer ( 10 ) ;





    // Fill it with 20 items


    for  ( $i = 0 ; $i  <  20 ; $i ++ )


        $buffer []    =  "Item #" . ( $i + 1 ) ;





    // Print the items contained in the circular buffer (this will show the string "Item #11" through "Item #20"


    echo "*** Contents of the circular buffer :\n" ;





    foreach  ( $buffer  as  $item ) 


        echo "\t$item\n" ;





    echo "*** Number of items in the circular buffer : " . count ( $buffer ) . "\n" ;


    echo "*** Contents of the 1st circular buffer item : {$buffer [0]}\n" ;
