有没有一种方法可以用PHP中的LESS编译器覆盖LESS变量? [英] Is there a way I can overwrite LESS variable with LESS compiler in PHP?

问题描述

目前，我正在使用 lessphp 作为我的LESS编译器.我知道它提供了一种设置LESS变量的方法，但是有一种方法可以覆盖文件中设置的变量吗?

Currently I am using the lessphp as my LESS compiler. I know it provides a way to set the LESS variables, but is there a way to overwrite the variables set in the file?

例如，我有以下LESS文件:

For example, I have the following LESS file:

@theme-color: #000055;
h1 {
    color: @theme-color;
}
h2 {
    color: @theme-color * 1.3;
}
h3 {
    color: @theme-color * 1.5;
}

要在PHP中进行编译，

To compile it in PHP,

require"path/to/leafo/lessphp/lessc.inc.php";
$less = new lessc;
$less->setVariables(array(
    "theme-color" => "#000055"
));
$less->compileFile("basic/path/less/main.less", "basic/path//css/main.css");

它成功编译了文件，但是变量@ theme-color未被覆盖.有没有办法覆盖它?

It successfully compile the file but the variable @theme-color is not overwritten. Is there a way to overwrite it?

如果需要的话，我不介意使用其他编译器，但是它需要在服务器端使用，因为javascript编译器的速度太慢，并且会导致片刻没有CSS视图.

I don't mind using another compiler if necessary, but it needs to be server side as the javascript compiler is too slow and it creates a moment of no css view.

推荐答案

可能可以使用compile()代替compileFile();

$lesscode = file_get_contents("basic/path/less/main.less");
$lesscode .= "@themecolor: #000055;";

file_put_contents("basic/path//css/main.css", $less->compile($lesscode));
