I have combined and minified multiple CSS files into one string, like this:
@import "path/to/file1";.my-class{font-size:24px;}@import "path/to/file2";
But now I want to "turn off" importing. So, I want to remove all instances of @import "something"; and get this:
.my-class{font-size:4px;}
I am currently using this:
echo preg_replace("(@import \".*\";)", "", $minified_css);
But that replaces the whole string. i.e., It's not stopping at the first instance of "; and restarting.
How do I get the regex to replace the individual @import instances?
You should preferable use this regex,
@import\s+"[^"]+";
And remove it with empty string
Also, in your regex (@import \".*\";) avoid using ( ) as you don't need to uselessly group your regex when you are replacing it with empty string. Also avoid usage of .* else it will greedily match everything possible and may give you unexpected results.
Try this PHP code snippet,
$minified_css = '@import "path/to/file1";.my-class{font-size:24px;}@import "path/to/file2";';
echo preg_replace('/@import\s+\"[^"]+\";/', '', $minified_css);
Prints,
.my-class{font-size:24px;}
I don't think you need to use global g modifier in preg_replace as that happens by default and you can control the replacement number by passing a third parameter. Also, you don't need to use m multiline modifier as we aren't use start/end anchors in our pattern.
