为运行中的PHP批量短信脚本添加Resume/Pause/Stop网页控制界面咨询

Hey there! Let's figure out how to add pause/play/stop controls to your bulk SMS PHP script. The key here is that since PHP runs synchronously by default, we need a way to track the script's state externally and have the sending loop check that state periodically. Here's a practical implementation:

Core Concept #

We'll use state marker files (or a database/Redis if you prefer) to signal the running script to pause, resume, or stop. The sending loop will regularly check these markers and adjust its behavior accordingly.

Step 1: Add State Tracking with Marker Files #

We'll create three simple marker files to track the script's state:

• pause.lock: Exists when the script should pause
• stop.lock: Exists when the script should terminate
• No lock files: The script runs normally

Step 2: Modify Your sendsms.php Script #

Update your sending loop to check these marker files on each iteration:

<?php
// Clean up old lock files on script start (optional but recommended)
foreach (['pause.lock', 'stop.lock'] as $file) {
    if (file_exists($file)) unlink($file);
}

// Your existing logic to get phone numbers
$phoneNumbers = get1MPhoneNumbers(); // Replace with your actual number retrieval
$message = $_POST['message']; // From your original form

foreach ($phoneNumbers as $index => $number) {
    // Check if stop is requested
    if (file_exists('stop.lock')) {
        unlink('stop.lock'); // Clean up marker
        exit("SMS sending stopped by user. Processed {$index} numbers.");
    }

    // Check if pause is requested: wait until resume or stop
    while (file_exists('pause.lock')) {
        if (file_exists('stop.lock')) {
            unlink('stop.lock');
            unlink('pause.lock');
            exit("SMS sending stopped during pause. Processed {$index} numbers.");
        }
        sleep(2); // Wait 2 seconds before checking again (reduces resource usage)
    }

    // Execute your SMS sending logic
    if (sendSMS($number, $message)) {
        // Optional: Log successful send or update progress
        file_put_contents('progress.log', "Sent to {$number}\n", FILE_APPEND);
    }

    // Optional: Add a small delay to avoid hitting SMS platform rate limits
    sleep(1);
}

// Clean up on completion
if (file_exists('pause.lock')) unlink('pause.lock');
echo "SMS sending completed successfully!";
?>

Step 3: Build the Control Interface #

Create an HTML page with buttons to trigger pause/play/stop actions, using AJAX to avoid page reloads:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Bulk SMS Controller</title>
    <script src="https://code.jquery.com/jquery-3.7.1.min.js"></script>
</head>
<body>
    <h1>Bulk SMS Sender Controls</h1>
    <div style="margin: 20px 0;">
        <button id="resumeBtn" style="padding: 10px 20px;">Play/Resume</button>
        <button id="pauseBtn" style="padding: 10px 20px; margin-left: 10px;">Pause</button>
        <button id="stopBtn" style="padding: 10px 20px; margin-left: 10px;">Stop</button>
    </div>
    <div id="status" style="margin-top: 20px; padding: 10px; border: 1px solid #ccc;"></div>

    <script>
        // Handle Resume/Play
        $('#resumeBtn').click(function() {
            $.post('control.php', { action: 'resume' }, function(response) {
                $('#status').text(response);
            });
        });

        // Handle Pause
        $('#pauseBtn').click(function() {
            $.post('control.php', { action: 'pause' }, function(response) {
                $('#status').text(response);
            });
        });

        // Handle Stop
        $('#stopBtn').click(function() {
            $.post('control.php', { action: 'stop' }, function(response) {
                $('#status').text(response);
            });
        });

        // Optional: Auto-refresh status (e.g., check progress)
        setInterval(function() {
            $.get('progress.php', function(data) {
                // Update progress display if you implement progress tracking
            });
        }, 5000);
    </script>
</body>
</html>

Step 4: Create the Control Handler (control.php) #

This script processes AJAX requests to create/remove marker files:

<?php
if ($_SERVER['REQUEST_METHOD'] !== 'POST') {
    http_response_code(405);
    echo "Invalid request method.";
    exit;
}

$action = $_POST['action'] ?? '';

switch ($action) {
    case 'pause':
        if (!file_exists('pause.lock')) {
            file_put_contents('pause.lock', '');
            echo "SMS sending paused successfully.";
        } else {
            echo "Sending is already paused.";
        }
        break;

    case 'resume':
        if (file_exists('pause.lock')) {
            unlink('pause.lock');
            echo "SMS sending resumed successfully.";
        } else {
            echo "Sending is already running.";
        }
        break;

    case 'stop':
        file_put_contents('stop.lock', '');
        if (file_exists('pause.lock')) unlink('pause.lock');
        echo "Stop request sent. Sending will terminate shortly.";
        break;

    default:
        http_response_code(400);
        echo "Invalid action.";
        break;
}
?>

Key Considerations #

• File Permissions: Ensure your PHP process has read/write access to the directory where marker files are stored. If you get permission errors, adjust the directory's chmod or ownership.
• Alternative State Stores: For more reliability (especially in multi-server setups), replace marker files with a Redis key-value store or a database table. For example, use Redis SET to mark pause/stop and DEL to resume.
• Progress Tracking: Extend the script to write progress (e.g., number of sent messages) to a file or database, then add a progress bar to the control interface.
• Timeouts: If your script runs longer than PHP's max_execution_time, you'll need to increase this setting in php.ini or use set_time_limit(0); at the start of sendsms.php.
