discuz! 5.0 forum display style PHP code highlighting plug-in,
syntax coloring PHP code, comrades who like PHP can easily read the code.
At the same time, the html code running function has been added.
This plug-in is modified based on the php code highlighting of Discuz!4 released by someone before.
In addition, my PHP learning has entered a stagnant state.
I hope someone can help me get out of the PHP learning dilemma

Function: Posting Use the [php]php code[/php] tag to highlight php code, and use the [runcode]Html code[/runcode] tag to run HTML code (running on the client, not the server).

The steps to add the plug-in are as follows:
1. Modify include/common.js
Find

Copy the code The code is as follows:

function copycode(obj) { 
 var rng = document.body.createTextRange(); 
 rng.moveToElementText(obj); 
 rng.scrollIntoView(); 
 rng.select(); 
 rng.execCommand("Copy"); 
 rng.collapse(false); 
}

Add below the end of this function:

Copy code The code is 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 The code is as follows:

           $discuzcodes['codecount']++;                                                                                                                                          >

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

Copy code

The code is as follows:

//------- 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']] = "

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,"                $code = '<'.'?'.trim($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('', '', $buffer);
        return $buffer;
}
//------- 结束

3.继续修改include/discuzcode.func.php
查找

复制代码代码如下:

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

在其下面继续添加：

复制代码代码如下:

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