can any one give me Regex to match any character including new lines

Try this: 

(.|\n)*

In regular expressions, the dot or period is one of the most commonly used metacharacters. Unfortunately, it is also the most commonly misused metacharacter.

The dot matches a single character, without caring what that character is. The only exception are line break characters. In all regex flavors discussed in this tutorial, the dot does not match line breaks by default.

the correct REGX

.*\\r\\n

try

Use the "s" modifier

preg_match('/.*/s', $text, $match);
