Function: When posting, use [php]php code [/php] tag to highlight the PHP code,
Use the [runcode]html code [/runcode] tag to run the HTML code (non-server running on the client).

Plug-in add steps as follows:
1. Modify Include/common.js
Find

Copy Code code as follows:

function Copycode (obj) {
var rng = Document.body.createTextRange ();
Rng.movetoelementtext (obj);
Rng.scrollintoview ();
Rng.select ();
Rng.execcommand ("Copy");
Rng.collapse (FALSE);
}

At the end of this function, add the following:

Copy Code code as follows:

function RunCode (obj) {
var winname = window.open ("," _blank ",");
Winname.document.open (' text/html ', ' replace ');
Winname.document.writeln (Obj.value);
Winname.document.close ();
}

function Savecode (obj) {
var winname = window.open (', ' _blank ', ' top=10000 ');
Winname.document.open (' text/html ', ' replace ');
Winname.document.writeln (Obj.value);
Winname.document.execCommand (' SaveAs ', ', ', ' code.htm ');
Winname.close ();
}

2. Modify include/discuzcode.func.php
Find

Copy Code code as follows:

$discuzcodes [' Codecount ']++;
Return "[\tdiscuz_code_$discuzcodes[pcodecount]\t]";
}

(Note: You can also use EditPlus directly to find the 110th line of code to do the following add)
Continue to add below:

Copy Code code as follows:

-------Add [RunCode] HTML code [/runcode] to run the HTML code
function Runcodedisp ($code) {
Global $discuzcodes;
$discuzcodes [' Pcodecount ']++;
$code = Htmlspecialchars (str_replace (' \ "', '" '), Preg_replace ("/^[\n\r]*" (. +?) [\n\r]*$/is "," \\1 ", $code)));
         $discuzcodes [' codehtml '] [$discuzcodes [' Pcodecount ']] =   "<br><br><div class=\" smalltxt\ " style=\" margin-left: 2em;  Margin-right: 2em\ "><textarea name=\" runcode$discuzcodes[codecount]\ " rows=\" 1\ "  Cols=\ "95\"  style=\ "height:200px\" > $code </textarea><br><input type=\ "button\"  value=\ "Run code \  onclick=\" RunCode (runcode$discuzcodes[codecount) \ "> <input type=\" button\ " value=\" copy code \ " onclick=\" Copycode (Runcode$discuzcodes[codecount]) \ "> <input  type=\ "button\"  value=\ "Save code \"  onclick=\ "Savecode (Runcode$discuzcodes[codecount]) \" >  <script language=\ "Javascript\" &GT;FFCOD&NBSP;=&NBSP;DELPOST.RUNCODE$DISCUZCODES[CODECOUNT]&NBSP; Value; ffcod = ffcod.replace (/<br \/>/g, ');  delpost.runcode$discuzcodes[ Codecount] .value = ffcod;</script>  Tip: You can modify some of the code before running </div><br>; 
$discuzcodes [' Codecount ']++;
Return "[\tdiscuz_code_$discuzcodes[pcodecount]\t]";
}

-------Add [PHP] PHP code [/php] to highlight the PHP code, for PHP syntax coloring
function Phpcodedisp ($code) {
Global $discuzcodes;
$discuzcodes [' Pcodecount ']++;
$code = Phphighlite (Str_replace ("\\\", "\" ", $code));
$discuzcodes [' codehtml '] [$discuzcodes [' pcodecount ']] = "<br><div class=\" msgheader\ "><div class=\" Right\ "><a href=\" ###\ "class=\" smalltxt\ "Onclick=\" Copycode ($ (' phpcode$discuzcodes[codecount] '); \ ">[ Copy the PHP code]</a></div>php code as follows: </div><div class=\ "Msgborder\ id=\" Phpcode$discuzcodes[codecount ]\ "> $code </div><br>";
$discuzcodes [' Codecount ']++;
Return "[\tdiscuz_code_$discuzcodes[pcodecount]\t]";
}

function Phphighlite ($code) {
if (!strpos ($code, "<?\n") &&!strpos ($code, ';? ') && substr ($code, 0,2)!= ' {
$code = ' < '. Trim ($code). ' > ';
$addedtags = 1;
}
Ob_start ();
$oldlevel = error_reporting (0);
Highlight_string ($code);
Error_reporting ($oldlevel);
$buffer = Ob_get_contents ();
Ob_end_clean ();
if ($addedtags) {
$openingpos = Strpos ($buffer, ';? ');
$closingpos = Strrpos ($buffer, '? ');
$buffer = substr ($buffer, 0, $openingpos). substr ($buffer, $openingpos +5, $closingpos-($openingpos +5)). substr ($buffer , $closingpos +5);
}
$buffer = Str_replace (' "," \ "), $buffer);
$buffer = Str_replace (' <br/> ', ', $buffer);
return $buffer;
}
-------End

3. Continue to modify include/discuzcode.func.php
Find

Copy Code code as follows:

$message = Preg_replace ("/\s*\[code\]" (. +?) \[\/code\]\s*/ies "," Codedisp (' \\1 ') ", $message);

Continue to add below:

Copy Code code as follows:

-------RunCode
$message = Preg_replace ("/\s*\[runcode\]" (. +?) \[\/runcode\]\s*/ies "," Runcodedisp (' \\1 ') ", $message);
-------PHP
