坑爹的正则，请问

config.php



$_LANG['new_arrival']       = 'New Arrivals';

$_LANG['hot_products']   = 'Hot Products';

$_LANG['group_deals']     = 'Group Deals';

$_LANG['specials']            = "Specials";

$_LANG['after']            = 'Contact cu\'stomer 



service for
 
order status and
  
other after-sales issues
'; 

$_LANG['group_deals']     = 'Group Deals'; 



$subject = file_get_contents("config.php");

$pattern = '这里正则要如何写呢'; 

preg_match_all($pattern, $subject, $matches); 

print_r($matches);



我要取出等号后面的所有内容，正则要怎样写呢？ 

请注意等号后面字符串中的符号（单引号，双引号，转义符己及换行都要取到）。



结果如下：

1. 'New Arrivals' 

2. 'Hot Products' 

3. 'Group Deals'

4. "Specials"

5.  'Contact cu\'stomer 



service for
 
order status and
 
other after-sales issues
'

$subject =<<< 'TXT'

$_LANG['new_arrival']       = 'New Arrivals';

$_LANG['hot_products']   = 'Hot Products';

$_LANG['group_deals']     = 'Group Deals';

$_LANG['specials']            = "Specials";

$_LANG['after']            = 'Contact cu\'stomer 



service for
 
order status and
  
other after-sales issues
';
