Preg_replace in php

I want to replace content from a string which is contained within {content}. It an be开发者_JAVA技巧 multilines etc. The preg_replace function should remove the whole { com no mat ment }

---

Try this:

$result = preg_replace('/\{[^}]*\}/s', 'replacement content', $subject);

---

Update

$str = preg_replace('/(?<=\{).+?(?=\})/s', '', $str);

See it.

---

preg_match_all('/{*([^}]+*)}/s'), $content, $matches)

---

How is this?

preg_match_all('/\{([^}]+\)}/s'), $content, $matches)

You need the s modifier to make the expression work with newlines. The $matches array will contain all the matching segments which you can then replace.
