在不超过时间限制的情况下保存多个csv的内容

为了扩展我关于设置参数和重定向的评论,下面是一个简单的例子。

在其基本要素中,脚本可以如下所示:

// require the ?file= parameter to exist
if (empty($_GET['file'])) {
    echo 'No file-parameter provided.';
    exit();
}

$file = $_GET['file'];

// build the full path to the file
$filename = get_template_directory_uri() . '/lines' . $file . '.csv';

// make sure the file exists, this will make sure the script stops
// when the last file has been processed
if (!file_exists($filename)) {
    echo 'File ' . $file . ' does not exist. Processing may be complete.';
    exit();
}

// read and process the file
$lines = file($filename, FILE_IGNORE_NEW_LINES);
foreach ($lines as $line_num => $line){
    // process this line
}

// build the URL to the next file
$next_script = $_SERVER['PHP_SELF'] . '?file=' . ($file + 1);

// set a HTTP/1.1 307 Temporary Redirect header and tell the browser
// where to go
http_response_code(307);
header('Location: ' . $next_script);
exit();

现在,您可以通过转到开始导入过程 http://example.com/script.php?file=1 .

请注意,对于使用 header() 函数工作时,不能先输出任何内容。 标题() 设置HTTP响应头,该头必须在响应体(如HTML、Javascript等)之前发送到浏览器。

如果不能保证这一点,另一种解决方案是使用javascript重定向:

// build the URL to the next file
$next_script = $_SERVER['PHP_SELF'] . '?file=' . ($file + 1);

// redirect using javascript
echo '<script>window.location.href = "' . $next_script . '";</script>';
exit();
