Regex: delete all text inside double quotes (including multi-line)

It is difficult for me to remove the text in double quotes, especially those that spread over several lines:

$file=file_get_contents('test.html');

$replaced = preg_replace('/"(\n.)+?"/m','', $file);

I want to remove ALL text in double quotes (included). Some texts inside them will be spread over several lines.

I read that new lines may be \r\nand \n.

Try the following expression:

"[^"]+"

Also make sure you replace globally (usually with a flag g- my PHP is rusty, so check the docs).

$replaced = preg_replace('/"[^"]*"/s','', $file);

will do it for you. However, note that it will not allow the use of any quoted double quotes (for example, it A "test \" quoted string" Bwill result in A quoted string" Ba leading space, not in A B, as you might expect.
