lessphp 0.3.7 and above has a new PHP api

[scottsweb]

The latest versions of lessphp requires a change to wp-less. From line 125 I have made the following changes:

// automatically regenerate files if source's modified time has changed or vars have changed
try {

    // load the cache
    $cache_path = "{$css_path}.cache";

    if (file_exists($cache_path))
        $full_cache = unserialize( file_get_contents( $cache_path ) );

    // If the root path in the cache is wrong then regenerate
    if ( ! isset( $full_cache[ 'less' ][ 'root' ] ) || ! file_exists( $full_cache[ 'less' ][ 'root' ] ) )
        $full_cache = array( 'vars' => $vars, 'less' => $less_path );

    // *** different approach to setting variables from php and compiling from cache ***
    $less = new lessc();
    $less->setVariables($vars);
    $less_cache = $less->cachedCompile($full_cache['less']);

    if ( ! is_array( $full_cache ) || $less_cache[ 'updated' ] > $full_cache['less']['updated'] || $vars !== $full_cache[ 'vars' ] ) {      
        file_put_contents( $cache_path, serialize( array( 'vars' => $vars, 'less' => $less_cache ) ) );
        file_put_contents( $css_path, $less_cache['compiled']);
    }
}

I would not necessarily make the changes yet though as lessphp 0.3.8 is not working particularly well for me at the moment and has introduced a heap of new bugs.

It might also be worth looking at the new output formatting (http://leafo.net/lessphp/docs/#output_formatting) options in order to compress the compiled CSS further.

Thanks for letting me know and fort the code Scott.

I'll wait for another point release or two or perhaps make a branch for the updated lessphp.

Latest update uses 0.3.8 and adds a few extra functions
