      As of PHP 5.2.0 <CODE
CLASS="parameter"

      be specified to begin searching an arbitrary number of characters into
      the string.  Negative values will stop searching at an arbitrary point

      The <CODE

>encoding</CODE
> parameter was moved from
      the third position to the fourth in PHP 5.2.0.  For backward
      compatibility, <CODE
CLASS="parameter"
>encoding</CODE
> can be specified
      as the third parameter, but doing so is deprecated and will be
      removed in the future.
