preg_replace only replaces first occurrence then skips to next line

Question

Got a problem where preg_replace only replaces the first match it finds then jumps to the next line and skips the remaining parts on the same line that I also want to be replaced.

What I do is that I read a CSS file that sometimes have multiple "url(media/pic.gif)" on a row and replace "media/pic.gif" (the file is then saved as a copy with the replaced parts). The content of the CSS file is put into the variable $resource_content:

$resource_content = preg_replace('#(url\((\'|")?)(.*)((\'|")?\))#i', '${1}'.url::base(FALSE).'${3}'.'${4}', $resource_content);

Does anyone know a solution for why it only replaces the first match per line?

Answer 1

Try:

$resource_content = preg_replace('#(url\((\'|")?)(.*?)((\'|")?\))#i', '${1}'.url::base(FALSE).'${3}'.'${4}', $resource_content);

That will keep the (.*) term from matching "too much" content.
