在PHP中自动从URL下载文件？

<?php
function downloadFileFromUrl($url, $savePath) {
    $urlInfo = parse_url($url);
    $filename = basename($urlInfo['path']);
    $filePath = $savePath . $filename;
    
    $fileHandle = fopen($filePath, 'wb');

    $curlHandle = curl_init();
    curl_setopt($curlHandle, CURLOPT_URL, $url);
    curl_setopt($curlHandle, CURLOPT_FILE, $fileHandle);
    curl_setopt($curlHandle, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($curlHandle, CURLOPT_TIMEOUT, 300);
    curl_exec($curlHandle);
    curl_close($curlHandle);

    fclose($fileHandle);
}

// 调用示例
$url = 'https://example.com/file.zip';
$savePath = '/path/to/save/files/';
downloadFileFromUrl($url, $savePath);
?>
