I recently worked on a project that involved cutout,

but the webp format cannot be displayed on Firefox

Solution:

//webp转换成jpg格式
function webptojpgapi($inputurl,$inputname){
    $apiurl = "https://api.cloudconvert.com/convert?apikey=[自己的apikey]&input=download&filename=$inputname&download=false&save=true&inputformat=webp&outputformat=jpg&file=$inputurl";
    $res = file_get_contents($apiurl);
    $res = json_decode($res,true);
    return $res['output']['url'].'/'.str_replace('webp','jpg',$inputname);
}

There are instructions on the official website, this is the specifics,

But there is an inconvenience, the fee, oh, it’s a rip-off, so Another approach was adopted.

Call the system library, the code is as follows, it looks very classy

if($ext=='webp'){
      $img_pathwebp = "Runtime/yy_".time().rand_string(3).'.png';
@file_put_contents($img_pathwebp, file_get_contents($img_path));
      $img_pathwebp = realpath($img_pathwebp);
$pic_path  = $img_pathwebp ; 
      
      @system("dwebp $img_pathwebp -o $pic_path", $retval);
 }
