Replace text between @import and \n with preg_replace (PHP)?

[Mehdi]

I use PHP.I'm working on a way to automatically put together all my CSS files into one. I automatically load the CSS-files and then saves them to a larger one, for upload.In my local installation I have some @import lines that needs to be removed.It looks like this:\[code\]@import url('css/reset.css');@import url('css/grid.css');@import url('css/default.css');@import url('css/header.css');@import url('css/main.css');@import url('css/sidebar.css');@import url('css/footer.css');body { font: normal 0.75em/1.5em Verdana; color: #333; }\[/code\]If the style above is within a string, how do I the best way replace the @import-lines with preg_replace or better? It would be nice to not leave a whitespace gap.
