I was trying some new things with php today, and was commenting above each
little bit to better see what was working and/or displaying versus what was
not. My comment delineator consisted of the following:
[code]
echo '<br><br><font color="#bbbbbb"><i> this is a comment displayed in html
</i></font><br><br>';
[/code]
Then I decided to create a cool function to write that code for me every
time I wanted to write a comment formatted in HTML, so to write a comment
saying "this is a comment", I would call a function:
[code]
comment("this is a comment");
[/code]
It was working wonderfully, until I wanted to display "test of $newComment"
as a comment.
[code]
comment("test of $newComment");
[/code]
This rendered a comment that said "test of ".
So I added a \ before the $ to make it display properly, but I was wondering
if there was a way that the function could work so that it will display
anything you type within the quotes in comment(" ").
Here is my original code for the function comment() :
[code=function comment()]
function comment($commentText = "empty comment")
{
echo '<br><br><font color=#bbbbbb>Comment:</font><br>';
echo '<font color=#bbbbbb><i>'. $newComment .'</i></font><br><br>';
}
[/code]
This would return gray text in 2 lines, Comment: then a line return with the
comment the developer put within the comment() function call in italics.
After noticing that I MUST escape the dollar sign for it to display a
function name in a comment, I tried the following:
[code]
function comment($commentText = "empty comment")
{
$healthy = "\$";
$yummy = "$";
$newComment = str_replace($healthy, $yummy, $commentText);
echo '<br><br><font color=#bbbbbb>Comment:</font><br>';
echo '<font color=#bbbbbb><i>'. $newComment .'</i></font><br><br>';
}
[/code]
This still does not produce the desired results, I still have to escape the
$ when I call the comment() function for the variable name to display.
Again, not a big deal, but I don't want this to beat me.
Anyone have any ideas?
Additionally, when I try to echo $newComment, nothing shows on the screen.
Is this because variables are reset or set to null, or cleared at the end of
a function in which they are used?
