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

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']] = "
";
$discuzcodes['codecount']++;
return "[\tDISCUZ_CODE_$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);

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
