Highlight a specific word

suntra

Hi !

What function (preg_replace ?) and what expression whould I use to highlight a specific word between to HTML tags in a HTML document ?

Example :
Font is a very useful tag because...

If I want to highlight the word "font" without highlighting what's between "<" and ">" ( and </FONT), what must I do ?

I don't know anything to regular expression. I understand almost nothing. I tried several things, but nothing worked...

Thanks !

try this

$message = "This is my new word";
$message = preg_replace("word","<font color=\"#FFF333\">word</font>",$message);
echo $message;

Try that

No !

That's not what I want !

Suppose I want to highlight a word which can be a HTML tag... like I used, font... I don't want PHP to highlight the word FONT present in a tag... if it does that, I will have HTML errors...

I'd like something like >word< where * means everything... in short, I only want to highlight the word X present between HTML tags...

The thing is if your highlighting the file it will highlight the html otherwise it works.. I changed it just a bit

$message = "This is my new word";
$word="This";
$message = eregi_replace($word,"<font color=\"#FFF333\">$word</font>",$message);
echo $message;

If this is not what you want. Explain yourself more.

This will not search your html as well

But what if

$message = "This is my new font";

$word="font";

Your code

$message = eregi_replace($word,"$word",$message);

would output

<font>This</font> is m
y new font

but suntra wants:

This is my new font

i.e. suntra doesn't want the font tag to be highlighted. But he also wants it to be general, i.e. the code would have to ignore any tag, not just the font tag.
