修改代码片段 1

$content = preg_replace('#(\\s*)\\[cc([^\\s\\]_]*(?:_[^\\s\\]]*)?)([^\\]]*)\\](.*?)\\[/cc\\2\\](\\s*)#sie', '$this->PerformHighlightCodeBlock(\\'\\\\4\\', \\'\\\\3\\', $content, \\'\\\\2\\', \\'\\\\1\\', \\'\\\\5\\');', $content);
$content = preg_replace('#(\\s*)\\<code(.*?)\\>(.*?)\\(\\s*)#sie', '$this->PerformHighlightCodeBlock(\\'\\\\3\\', \\'\\\\2\\', $content, \\'\\', \\'\\\\1\\', \\'\\\\4\\');', $content);

变更为

$content = preg_replace_callback('#(\\s*)\\[cc([^\\s\\]_]*(?:_[^\\s\\]]*)?)([^\\]]*)\\](.*?)\\[/cc\\2\\](\\s*)#si', function($r){

return $this->PerformHighlightCodeBlock($r[3], $r[2], $content, '', $r[1], $r[4]);
}, $content);

修改代码片段 2

$text = preg_replace('~*([0-9a-f]+);~ei', 'chr(hexdec("\\\\1"))', $text);
$text = preg_replace('~*([0-9]+);~e', 'chr(\\\\1)', $text);

变更为

$text = preg_replace_callback('~*([0-9a-f]+);~i', function($r){

}, $text);
$text = preg_replace_callback('~*([0-9]+);~', function($r){

$content = preg_replace('#(\\s*)(\\<code.*?\\>.*?\\)(\\s*)#sie', '$this->PerformProtectComment(\\'\\\\2\\', $content, \\'\\\\1\\', \\'\\\\3\\');', $content);

变更为

}, $content);

修改代码片段 4

$text = preg_replace('/(&lt; \\?php)/i', '<!--?php', $text);&lt;br ?--> $text = preg_replace('/(?:^(?:\\s*[\\r\\n])+|\\s+$)/', '', $text);

变更为

$text = preg_replace_callback('/(< \\?php)/i', function($r){
return '<!--?php'; &lt;br ?--> }, $text);
$text = preg_replace_callback('/(?:^(?:\\s*[\\r\\n])+|\\s+$)/', function($r){
