Homephp教程php手册Discuz!5的PHP代码高亮显示插件(黑暗中的舞者更新)

discuz!5.0论坛显示风格的php代码高亮显示插件,
把php代码进行语法着色,喜欢PHP的同志可以轻松的看代码啦。
同时添加了html代码运行功能。
此插件是在以前某位同志发布的Discuz!4的php代码高亮显示基础之上修改完成。
另外,本人的php学习进入了停滞状态,
希望有人能帮助我走出php的学习困境
My QQ:5642382  我的QQ群:2577162

功能:发贴时使用[php]php代码[/php]标记来高亮显示php代码,
      使用[runcode]Html代码[/runcode]标记来运行HTML代码(在客户端运行非服务器)。

插件添加步骤如下:
1.修改include/common.js
  查找
function copycode(obj) {
        var rng = document.body.createTextRange();
        rng.moveToElementText(obj);
        rng.scrollIntoView();
        rng.select();
        rng.execCommand("Copy");
        rng.collapse(false);
}
在这个函数结束的下面添加:


[Copy to clipboard] [ - ]CODE:
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.修改include/discuzcode.func.php
  查找


[Copy to clipboard] [ - ]CODE:
        $discuzcodes['codecount']++;
        return "[\tDISCUZ_CODE_$discuzcodes[pcodecount]\t]";
}
(注:也可以用Editplus直接查找到代码的第110行来进行下面的添加)
在下面继续添加:


/------- 添加 [runcode] Html代码 [/runcode] 来运行Html代码
function runcodedisp($code) { 
        global $discuzcodes; 
        $discuzcodes['pcodecount']++; 
        $code = htmlspecialchars(str_replace('\\"', '"', preg_replace("/^[\n\r]*(.+?)[\n\r]*$/is", "\\1", $code))); 
        $discuzcodes['codehtml'][$discuzcodes['pcodecount']] = "


   <script>ffcod = delpost.runcode$discuzcodes[codecount] .value; ffcod = ffcod.replace(/<br \/>/g,''); delpost.runcode$discuzcodes[codecount] .value = ffcod;</script> 提示:您可以先修改部分代码再运行

"; 
        $discuzcodes['codecount']++; 
        return "[\tDISCUZ_CODE_$discuzcodes[pcodecount]\t]"; 


//------- 添加  [php] php代码 [/php] 来高亮显示php代码,进行php语法着色
function phpcodedisp($code) { 
        global $discuzcodes; 
        $discuzcodes['pcodecount']++; 
        $code = phphighlite(str_replace("\\\"", "\"", $code)); 
        $discuzcodes['codehtml'][$discuzcodes['pcodecount']] = "
[复制PHP代码]
PHP代码如下:
$code

"; 
        $discuzcodes['codecount']++; 
        return "[\tDISCUZ_CODE_$discuzcodes[pcodecount]\t]"; 


function phphighlite($code) { 
        if(!strpos($code,"\n") && !strpos($code,'') && substr($code,0,2) != '') { 
                $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('
', '', $buffer); 
        return $buffer; 

//------- 结束
3.继续修改include/discuzcode.func.php
  查找



$message = preg_replace("/\s*\[code\](.+?)\[\/code\]\s*/ies", "codedisp('\\1')", $message);
在其下面继续添加:


[Copy to clipboard] [ - ]CODE:
//------- runcode 
$message = preg_replace("/\s*\[runcode\](.+?)\[\/runcode\]\s*/ies", "runcodedisp('\\1')", $message); 
//------- php 
$message = preg_replace("/\s*\[php\](.+?)\[\/php\]\s*/ies", "phpcodedisp('\\1')", $message);

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
