文件路径模板配置

模板使用变量替换

$filenameTemp =   '/uploads/{year}{mon}{day}/{filemd5}.{suffix}';  
$md5 = md5(time()); 
$tempValues = [
    '{year}'     => date("Y"),
    '{mon}'      => date("m"),
    '{day}'      => date("d"), 
    '{filemd5}'  => $md5, 
    '{suffix}'   => 'png', 
];   
$res = str_replace(array_keys($tempValues), array_values($tempValues), $filenameTemp);

echo $res;

结果：
