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); }

The $ text parameter in the first function is the code content in the markdown format document. The content in the markdown format is in this form.

{Code }}}

If the code block in markdown format is in this form{{{ Javascript: Code }}}
I wantjavascript:Submit the variable $ lang_code to $ codeblock and return the following html content:

$codeblock = "
$codeblock\n
";

I wantjavascript:Submit the variable $ lang_code to $ codeblock and return the following html content:

$codeblock = "
$codeblock\n
";

After this

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

Add the following two lines:

$lang_pos = strpos($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; }
