\nThis function will take a message passed in the argument and print it
\nout in the appropriate style object. So to print a message we can:<\/div>\n
\n<\/p>\n

<?php<\/p>\n

$Basic<\/span>-><\/span>TextOut<\/span>(<\/span>'This\u00a0is\u00a0my\u00a0test\u00a0message'<\/span>);
\n
<\/span>$Tbody<\/span>-><\/span>TextOut<\/span>(<\/span>'\u00a0--\u00a0kinda\u00a0neat,\u00a0huh?'<\/span>);<\/p>\n

<\/span>?>
\n
<\/span>
\n<\/span>
\n<\/code><\/font><\/div>\n

\nNotice, there are no <BR> between the two function calls so they will
\nprint on the same line. Also, I just wanted a smaller font for the
\nsecond part of the output and I had already declared that in $Tbody so I
\nused that. This is safe in this instance as the only other difference
\nbetween $Basic and $Tbody is “bgcol” and that isn’t used in this
\nfunction. Notice the “&nbsp;” in the function declaration? That is
\nthere so if no message is passed the function will print out a non-
\nbreaking space. Why will become clear later on.<\/div>\n
\nSo far we haven’t saved a lot of work. The last example is easier if
\nyou want to change font color and\/or size in the middle of a sentence
\nbut still doesn’t justify writing an entire class. How about we add to
\nthe functions:<\/div>\n
\n<\/p>\n

<?php<\/p>\n

<\/span>function\u00a0<\/span>TDOut\u00a0<\/span>(<\/span>$message<\/span>=<\/span>\"&nbsp;\"<\/span>,<\/span>$colspan<\/span>=<\/span>1<\/span>)\u00a0{<\/p>\n

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0PRINT\u00a0<\/span>\"<TD\u00a0COLSPAN=$colspan\u00a0BGCOLOR=\"$this->bgcol\"\u00a0\"<\/span>.
\n
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/span>\"ALIGN=\"$this->align\"\u00a0VALIGN=\"$this->valign\">\"<\/span>;
\n
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/span>$this<\/span>-><\/span>TextOut<\/span>(<\/span>$message<\/span>);
\n
\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0PRINT\u00a0<\/span>\"<\/TD>n\"<\/span>;<\/p>\n

}<\/p>\n

<\/span>?>
\n
<\/span>
\n<\/span>
\n<\/code><\/font><\/div>\n

\nNow, we’re getting somewhere! Remember, I wanted to have different
\nbackground colors for my tables. Now I can do this:<\/div>\n
\n
\n<TABLE>
\n
<TR>
\n
<?php<\/p>\n

$Theader<\/span>-><\/span>TDOut<\/span>(<\/span>\"Name\"<\/span>,<\/span>2<\/span>);
\n
<\/span>$Theader<\/span>-><\/span>TDOut<\/span>(<\/span>\"Location\"<\/span>,<\/span>3<\/span>);<\/p>\n

<\/span>?>
\n
<\/span><\/TR>
\n
<tr>
\n
<?php<\/p>\n

$Theader<\/span>-><\/span>TDOut<\/span>(<\/span>\"Last\"<\/span>);
\n
<\/span>$Theader<\/span>-><\/span>TDOut<\/span>(<\/span>\"First\"<\/span>);
\n
<\/span>$Theader<\/span>-><\/span>TDOut<\/span>(<\/span>\"City\"<\/span>);
\n
<\/span>$Theader<\/span>-><\/span>TDOut<\/span>(<\/span>\"State\/Province\"<\/span>);
\n
<\/span>$Theader<\/span>-><\/span>TDOut<\/span>(<\/span>\"Country\"<\/span>);<\/p>\n

<\/span>?>
\n
<\/span><\/tr>
\n
<\/span>
\n<\/code><\/font><\/div>\n

\nThere. See how the colspan argument works. If it’s not declared it
\ndefaults to 1. So in the first table row “Name” spans 2 columns and
\n“Location” spans 3. In the second row all of them cover a single
\ncolumn.<\/div>\n<\/div>\n
