PHP中的命令行进度条
我目前正在尝试向命令行脚本添加进度条，并尝试了各种解决方案（包括Zend和Console_ProgressBar）。它们共同的问题是，进度条不会固定在窗口的底部，因为在脚本期间，会输出新行和其他信息 有没有办法让进度条保持在终端的底部，但在脚本运行时仍能输出其他信息 [编辑] 我想出来了： 我不是直接输出到STDOUT，而是实际捕获变量内部的输出，而是使用PHP中的命令行进度条,php,Php,我目前正在尝试向命令行脚本添加进度条，并尝试了各种解决方案（包括Zend和Console_ProgressBar）。它们共同的问题是，进度条不会固定在窗口的底部，因为在脚本期间，会输出新行和其他信息 有没有办法让进度条保持在终端的底部，但在脚本运行时仍能输出其他信息 [编辑] 我想出来了： 我不是直接输出到STDOUT，而是实际捕获变量内部的输出，而是使用echochr（27）擦除屏幕[2J'然后将变量的内容输出到标准输出，然后附加我的进度条 <? /* Copyright (c) 20

希望有意义：）这是一个很好的cli进度条：
这是对上一个答案的改进，该答案处理终端大小并使用2行而不是1行。第一行是信息，如时间/百分比。第二行是进度条

其他答案似乎过于复杂。我的解决方案是在下一次更新之前简单地回显\033[0G转义序列，并将光标移回开头
function progressBar($done, $total) {
$perc = floor(($done / $total) * 100);
$left = 100 - $perc;
$write = sprintf("\033[0G\033[2K[%'={$perc}s>%-{$left}s] - $perc%% - $done/$total", "", "");
fwrite(STDERR, $write);
}
第一次调用该函数会输出进度条，后续每次调用都会用新的进度条覆盖最后一行

编辑：
我已将回音\r更改为转义序列\033[0G，现在应该可以在OSX和Linux/Unix上使用
编辑2：
根据@tbjers建议修复了第3行上可能出现的错误
编辑3：
更新了打印到STDERR的新版本，现在也在GitHub上：
编辑4：
现在使用composer:composer需要macroman/终端进度条
use TerminalProgress\Bar;
$pg = new Bar(1000);
for ($i = 0; $i < 1000; $i++) {
usleep(10000);
$pg->tick();
}
使用TerminalProgress\Bar；
$pg=新棒材（1000）；
对于（$i=0；$i<1000；$i++）{
美国LEEP（10000）；
$pg->tick（）；
}
以下内容适用于unix机器
#!/usr/bin/php
<?php
$iloop = "0"; /* Outside the loop */
while (true){
$warn = "Program running hold on!!\r";
if (strlen($warn) === $iloop+1){
$iloop = "0";
}
$warn = str_split($warn);
$iloop++;
$warn[$iloop] = "\033[35;2m\e[0m".strtoupper($warn[$iloop]);
echo " \033[7m".implode($warn);
usleep(90000);
}
目标是检索当前终端总计列。（使用tput
）
这是一个基地，准备扩大
#!/usr/bin/php
<?php
@ob_start();
$shell = system("tput cols");
@ob_end_clean();
for( $i= 0 ; $i < $shell ; $i++ ){ echo "█"; usleep(100000); }
这显示了phpecho
的主要独特之处：它不追加新行，而bashecho
追加新行
使用循环时，比如每隔一段时间检查一个条件，
另一个很好的警告跑步活动的方法是文本效果
#!/usr/bin/php
<?php
$iloop = "0"; /* Outside the loop */
while (true){
$warn = "Program running hold on!!\r";
if (strlen($warn) === $iloop+1){
$iloop = "0";
}
$warn = str_split($warn);
$iloop++;
$warn[$iloop] = "\033[35;2m\e[0m".strtoupper($warn[$iloop]);
echo " \033[7m".implode($warn);
usleep(90000);
}
下面使用strtoupper
和ansi代码反向视频进行演示
#!/usr/bin/php
<?php
$iloop = "0"; /* Outside the loop */
while (true){
$warn = "Program running hold on!!\r";
if (strlen($warn) === $iloop+1){
$iloop = "0";
}
$warn = str_split($warn);
$iloop++;
$warn[$iloop] = "\033[35;2m\e[0m".strtoupper($warn[$iloop]);
echo " \033[7m".implode($warn);
usleep(90000);
}
！/usr/bin/php
如果您想使用可以在不同终端上使用的东西，而不必担心兼容性，Ncurses就是一种选择
检查：
ncurses库提供了一个强大的框架，允许程序员以文本模式创建具有视觉吸引力的用户界面
关于这一点的主要PHP文档要点是：这是最好的答案，非常好。作为总结，该代码段的重要部分是呼应出“\r”
（需要双引号）在写出新行之前。该函数更糟糕的是，通常以$c=0而不是$c=1开始for循环。由于以$c=0开始，函数会出现除零异常。非常重要的是：如果使用宽度太“小”的tty，这将不起作用.事实上，在这种情况下，如果长线导致一个新行，则只会移动到新行的开头，\r而不是第一行。结果是一团糟。25年的编程，我才意识到我可以用\r
来做进度条。我刚刚发布了我的进度条：我尝试过这个，但不断添加新行。在Mac PHP CLIosx上测试使用s\r作为回车符和换行符，因此这在osx上不起作用。第3行应更改为以下内容，以避免出现来自str_repeat
：$bar=“[”（$perc>0？str_repeat（=”，$perc-1）：”）；
谢谢@tbjers我添加了您的代码以检查0以下的输入。我将使用ceil（）函数，以确保达到100%函数进度栏（$done，$total）{$perc=ceil（$done/$total）*100）；等等。
Brilliant！我需要的是\x1b[A
位来创建多行进度栏：）
