php 下面的函數怎麼改？

protected function doCodeBlocks($text)    {        #        #   Process Markdown `` blocks. # preg_match('/\{\{\{/i', $text, $_m_c_open); preg_match('/\}\}\}/i', $text, $_m_c_close); if (count($_m_c_open) == count($_m_c_close)) { $text = preg_replace_callback('/\{\{\{[ \n]*(.*?)\}\}\}/is', array( &$this, '_doCodeBlocks_callback' ), $text); } return $text; } protected function _doCodeBlocks_callback($matches) { $codeblock = $matches[1]; $codeblock = $this->outdent($codeblock); $codeblock = htmlspecialchars($codeblock, ENT_NOQUOTES); # trim leading newlines and trailing newlines $codeblock = preg_replace('/\A\n+|\n+\z/', '', $codeblock); $codeblock = str_replace(array( '&', "\t", ' ' ), array( '&', ' ', ' ' ), $codeblock); $codeblock = "
$codeblock\n
"; return $this->hashBlock($codeblock); }

這第一個個函數中的參數$text是markdown格式文章中的代碼內容，markdown 格式的內容是這種形式的

{{{ 代碼 }}}

如果markdown格式的代碼塊是這種形式的 {{{javascript: 代碼}}}
我想把javascript:用變數$lang_code的形式提交給$codeblock裡面，之後返回下面的html內容：

$codeblock = "
$codeblock\n
";

回複內容：

protected function doCodeBlocks($text)    {        #        #   Process Markdown `` blocks. # preg_match('/\{\{\{/i', $text, $_m_c_open); preg_match('/\}\}\}/i', $text, $_m_c_close); if (count($_m_c_open) == count($_m_c_close)) { $text = preg_replace_callback('/\{\{\{[ \n]*(.*?)\}\}\}/is', array( &$this, '_doCodeBlocks_callback' ), $text); } return $text; } protected function _doCodeBlocks_callback($matches) { $codeblock = $matches[1]; $codeblock = $this->outdent($codeblock); $codeblock = htmlspecialchars($codeblock, ENT_NOQUOTES); # trim leading newlines and trailing newlines $codeblock = preg_replace('/\A\n+|\n+\z/', '', $codeblock); $codeblock = str_replace(array( '&', "\t", ' ' ), array( '&', ' ', ' ' ), $codeblock); $codeblock = "
$codeblock\n
"; return $this->hashBlock($codeblock); }

$codeblock = "
$codeblock\n

在這個後面

# trim leading newlines and trailing newlines$codeblock = preg_replace('/\A\n+|\n+\z/', '', $codeblock);

加上下面這兩行試試:

$lang_pos = strpos($codeblock,":");$lang_code_pre = substr($codeblock, 3,$lang_pos - 3); switch ($lang_code_pre) {    case 'php':        $lang_code = "php";        break;    case 'javascript':        $lang_code = "javascript";        break;    default:        $lang_code = "default value";        break; }
