PHP-CLI 多行进度条

Posted 2022-12-13 Technofiend

我们使用php运行任务的时候，通常需要查看进度。要是能有一个像下载进度条一样直观的图就更好了。于是我做了一个。

<?php
/**

ini_set('max_execution_time', '0');

$percentStatus = [];

// 组合成进度条
function buildLine($percent) 
    $repeatTimes = 100;
    if ($percent > 0) 
        $hasColor = str_repeat('■', $percent);
     else 
        $hasColor = '';
    

    if ($repeatTimes - $percent > 0) 
        $noColor  = str_repeat(' ', $repeatTimes - $percent);
     else 
        $noColor  = '';
    

    $buffer      = sprintf("[$hasColor$noColor]");
    if ($percent !== 100) 
        $percentString = sprintf("[   %-6s]", $percent . '%');
     else 
        $percentString = sprintf("[    %-5s]", 'OK');;
    

    return $percentString . $buffer . "\\r";


// 输出进度条
function outputProgress($clear = false)

    global $percentStatus;

    if ($clear) 
        $number = count($percentStatus);
        for ($i=0; $i < $number; $i++)  
            system("tput cuu1");
            system("tput el");
        
    

    foreach ($percentStatus as $value) 
        echo buildLine($value) . "\\n";
    


// 更新进度条值
function updateProgressValue($k, $value) 
    $percentStatus[$k] = $value;
    if ($percentStatus[$k] >= 100) 
        $percentStatus[$k] = 100;
        outputProgress(true);
        return;
    

    outputProgress(true);
    usleep(50000);



$percentStatus[0] = 0;
$percentStatus[1] = 0;
$percentStatus[2] = 0;
$percentStatus[3] = 0;
$percentStatus[4] = 0;
$percentStatus[5] = 0;
$percentStatus[6] = 0;
$percentStatus[7] = 0;
$percentStatus[8] = 0;
outputProgress();
while(1) 
    $percentStatus[0] = rand(0, 100);
    $percentStatus[1] = rand(0, 100);
    $percentStatus[2] = rand(0, 100);
    $percentStatus[3] = rand(0, 100);
    $percentStatus[4] = rand(0, 100);
    $percentStatus[5] = rand(0, 100);
    $percentStatus[6] = rand(0, 100);
    $percentStatus[7] = rand(0, 100);
    $percentStatus[8] = rand(0, 100);
    outputProgress(true);
    usleep(500000);

大家可以复制上面代码，保存成为run.php
然后在linux下 运行 php run.php
