\nGreat, now what to we do with it? I’m glad you asked. We need to
\ncreate a few more functions within Style to actually accomplish
\nanything. The first thing I’d like to do is set up my page body so I
\ndid this:<\/div>\n
\n<\/p>\n

<?php<\/p>\n

<\/span>function\u00a0<\/span>Body<\/span>()\u00a0{<\/p>\n

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0PRINT\u00a0<\/span>\"<BODY\u00a0BGCOLOR=\"$this->bgcol\"\u00a0\"<\/span>.
\n
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/span>\"TEXT=\"$this->text\"\u00a0\"<\/span>.
\n
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/span>\"LINK=\"$this->link\"\u00a0VLINK=\"$this->vlink\"\u00a0\"<\/span>.
\n
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/span>\"ALINK=\"$this->alink\"><FONT\u00a0\"<\/span>.

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/span>\"FACE=\"$this->face\"\u00a0SIZE=$this->size>n\"<\/span>;<\/p>\n

\nThis sets up the page body for us. It also illustrates a new variable
\n“$this.” When used inside of a class function it lets the interpreter
\nknow we are referring to a variable of THIS instance. In other words,
\nit’s assigned the value of the name of the instance in the calling line
\n(e.g. $this would be == $Basic when $Basic->Body() is the calling
\nstatement.) Also, notice we are doing something here that’s much
\nsimpler than is possible in regular functions. We’re referring to
\nvariables that were not passed to the function. Remember, all functions
\nand variables of an instance are available to all functions of that
\ninstance. To do this with regular functions you’d have to set up
\nseveral global arrays.<\/div>\n
\nTry this in your php script (assuming you’ve included the Style class,
\ncreated the style objects above and sent the <HTML> and <HEAD><\/HEAD>
\ntags):<\/div>\n
\n
\n<?php\u00a0$Basic<\/span>-><\/span>Body<\/span>();\u00a0<\/span>?><\/span>
\n<\/span>
\n<\/code><\/font><\/div>\n
\nNow, we’re ready to print something out. We could do it the old
\nfashioned way, but I’m going to do something different… that’s right
\nanother function:<\/div>\n
\n<\/p>\n

<?php<\/p>\n

<\/span>function\u00a0<\/span>TextOut<\/span>(<\/span>$message<\/span>=<\/span>\"&nbsp\"<\/span>)\u00a0{<\/p>\n
