Discuz!论坛实现PHP代码高亮

插件演示地址：Discuz!论坛实现PHP代码高亮:

php程序员站

插件添加步骤如下： phperz.com

修改include/discuzcode.func.php

查找
[php]function codedisp($code) {
        global $discuzcodes;
        $discuzcodes['pcodecount']++;
        $code = htmlspecialchars(str_replace('\\"', '"', preg_replace("/^[\n\r]*(.+?)[\n\r]*$/is", "", $code)));
        $discuzcodes['codehtml'][$discuzcodes['pcodecount']] = tpl_codedisp($discuzcodes, $code);
        $discuzcodes['codecount']++;
        return "[\tDISCUZ_CODE_$discuzcodes[pcodecount]\t]";
}[/php] phperz.com

在下面添加：
CODE:

function phpcodedisp($code) {
        global $discuzcodes;
        $discuzcodes['pcodecount']++;
        $code = phphighlite(str_replace('\\"', '"', preg_replace("/^[\n\r]*(.+?)[\n\r]*$/is", "", $code)));
        $discuzcodes['codehtml'][$discuzcodes['pcodecount']] = "

复制内容到剪贴板

HP代码:

{$code}

";
        $discuzcodes['codecount']++;
        return "[\tDISCUZ_CODE_$discuzcodes[pcodecount]\t]";
} phperz.com

function phphighlite($code) {
        if(!strpos($code,"                $code = '<'.'?'.trim($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, '?'); www~phperz~com
                $closingpos = strrpos($buffer, '?');
                $buffer = substr($buffer, $openingpos+1, $closingpos-($openingpos+1)).substr($buffer, $closingpos+5);
        }
        $buffer = str_replace('"', "\"", $buffer);
        $buffer = str_replace('
', '', $buffer);
        return $buffer;
}
继续修改include/discuzcode.func.php
查找[php]if($parsetype != 1 && !$bbcodeoff && $allowbbcode) {
     $message = preg_replace("/\s*\[code\](.+?)\[\/code\]\s*/ies", "codedisp('\\1')", $message);
}[/php]在其下面添加：[php]
if($parsetype != 1 && !$bbcodeoff && $allowbbcode) { php程序员站
        $message = preg_replace("/\s*\[php\](.+?)\[\/php\]\s*/ies", "phpcodedisp('\\1')", $message);
}[/php]修改include/javascript/editor.js

查找
CODE:

insertText(text, strlen(opentag), strlen(closetag), in_array(tagname, ['code', 'quote', 'free', 'hide']) ? true : false);
修改为
CODE:

insertText(text, strlen(opentag), strlen(closetag), in_array(tagname, ['code', 'quote', 'free', 'hide', 'php']) ? true : false);
继续修改include/javascript/editor.js
