Php 正在新行上重新创建Symfony进度条

Symfony控制台进度条不是在同一行上前进，而是在新行上创建

 1/2 [==============>-------------]  50%
 ! [NOTE] No changes made to Categories/CategoriesSchema              


 2/2 [============================] 100%
 2/2 [============================] 100%

我假设进度条只会在同一条线上移动，直到操作完成。这是我的密码

$io = new SymfonyStyle($input, $output);
$progressbar = new ProgressBar($output, count($elements));
$progressbar->start();

foreach ($elements as $element) {

     //work on element
     io->note("No changes made to ".ucfirst($name));

     $progressbar->advance();
     $io->newLine();
}

$progressbar->finish();

我做错了什么？？？

如果不是自动的，则进程进程将始终位于新行，除非在向io写入之前清除它

如果要在进度条运行时输出某些内容， 先打电话。完成后，打电话向观众展示 再次显示进度条

因此，要么在启动进度条之前写入io

$io->note('No changes made to ' . ucfirst($name));
$io->newLine();

$progressbar->start();
foreach ($elements as $element) {
    $progressbar->advance();
    sleep(1);
}
$progressbar->finish();

或在写入io之前在进度条上调用clear，并在完成时调用display

$progressbar->start();
foreach ($elements as $element) {
    if (true /* put conditional here */) {
        $progressbar->clear(); //remove progress bar from display
        $io->note('No changes made to ' . ucfirst($name));
        $io->newLine();
        $progressbar->display(); //redraw progress bar in display
    }
    $progressbar->advance(); //move up a step
    sleep(1);
}    
$progressbar->finish();
