replace part of var using regex and highlight_string

**LORDGreg** · Nov 14, 2001 16:34

i have a text saved in variable and part of that var has [CCODE] in it. that CCODE should split the text between CCODE tags in variable and use the php function highlight_string on it..

here is how i wanted to do that:

PHP Code:


$patterns = array();

$replacements = array();



// code [ccode] to color code (highlight_string()<img src="images/smilies/wink.gif" border="0" alt="">

$patterns[0] = "#[CCODE](.*?)[/CCODE]#si";

$replacements[0] = "<hr>". highlight_string(\1) ."<hr>";



$text = "



blah blah blah

  

  [CCODE]

  <html>

  <head></head>

  <body>

  

  </body>

  </html>

  [/CCODE]

  

 

  weasel



";





$text = preg_replace($patterns, $replacements, $text);



echo $text;

but it just doesn't work..

can someone please help me with that? please, please,..

thank you very much all :P

I think your regex got corrupted when you posted. Try using the code tags next time when posting regex.

The main problem with the regex was that you needed to escape the metacharacters. Also, setting the patterns and replacements to arrays is fine, but when you're calling preg_replace, you're sending it a pointer, and not the values. Here's what I did and it seems to have worked:

Code:

// code [ccode] to color code (highlight_string()<img src="images/smilies/wink.gif" border="0" alt="">
$patterns = "/\[CCODE\](.*?)\[\/CCODE\]/si";
$replacements = "<hr>". highlight_string(1) ."<hr>";

$text = "

blah blah blah
  
  [CCODE]
  <html>
  <head></head>
  <body>
  
  </body>
  </html>
  [/CCODE]
  
 
  weasel

";


$text = preg_replace($patterns, $replacements, $text);

echo $text;

i tried your code and it doesn't work neither!

--
maybe the vbulletin -code- and -php- functions are doing something.. well doesn't matter.. what's wrong?

parse error? backslash? or mail me the code -> lordgreg@email.si..

thanks cupid :P

I'm sorry, I misread your question. I didn't realize that you were trying to highlight the stuff inside [ccode][/ccode]

Try this:

Code:

// code [ccode] to color code (highlight_string()<img src="images/smilies/wink.gif" border="0" alt="">

$text = "

blah blah blah

  [CCODE]
  <html>
  <head></head>
  <body>

  </body>
  </html>
  [/CCODE]


  weasel
";



if (preg_match("/\[CCODE\](.*?)\[\/CCODE\]/si", $text, $result))
       highlight_string(preg_replace("/\[(|\/)CCODE\]/i","",$text));
else echo $text;

that's great, but what about that text outside [CCODE]? i want that text also to apear! just like by vbulletin..

and how to color the text inside [CCODE]?

**cupid** · Nov 14, 2001 22:31

Hoo boy! I guess I got a little disoriented after all that regex

I threw in so much redundant/unneeded code in there. Check out the edited code. The color comes in when you have php code in there

some problems:

1. the code snippet you wrote works like this:
- if found any [ccode] tags in the text MAKE ALL $text highlight_string().
- else just echo the whole $text.

2. i wanted to be like this:

-input:

Code:

$text = "
  bla bla

  and here also bla

  [ccode]
  $here = "something";
  <pre>harhar</pre>
  <b>the bold text - source</b>
  [/ccode]

  and again some text outside the ccode tag
";

-output:
---------------------------------
bla bla

and here also bla

Code:

  $here = "something";
  <pre>harhar</pre>
  <b>the bold text - source</b>

and again some text outside the ccode tag
---------------------------------

that means only what's inside ccode tag, goes through highlight_string...

please please help
