Parse CSS in PHP

I need to parse a CSS file and chang开发者_StackOverflowe the path of an image in similar declarations to the following?

url("/images/...")

to basically change anything in between url("")

---

I want to replace

url('images/img.jpg'), url("images/img.jpg") 

and

url(images/img.jpg)

for url(/newpath/images/img.jpg)

I need to somehow get the current path so that I can append it to the new one

You can do this:

$line = "background-image: url(/images/image.png) no-repeat;";
//or $line = "background-image: url( /images/image.png ) no-repeat;";
echo preg_replace('/(?<=url\()[^\)]+(?=\))/x', '/newfolder/newimage.png', $line);

The regexp says:

• [^\)]+ string of 1 caracter or more, without )
• (?<=url\() before this string, there must be url(
• (?=\)) after the string, there must be )
• x whitespace data characters in the pattern are totally ignored except when escaped or inside a character class (more info).

Use regular expressions and preg_replace. Something like:

url\(([^\)]+)\)

Or you could serve your css files as php scripts via .htaccess, like this:

<FilesMatch "\.css$">
    php_value default_mimetype "text/css"
    SetHandler application/x-httpd-php
</FilesMatch>

And then in every css file you could defined your media path and use it wherever you want, like:

<?php define('MEDIA_PATH', '../images/'); ?>
.class{background-image:url(<?php echo MEDIA_PATH;?>background.jpg)}

Maybe you can try looking at: preg_replace()
