PHP 代码优化：处理 API 错误信息并更新文章内容

本文将优化一段 PHP 代码，使其更简洁和可读性更高。

原始代码：

$keys1 = [
    'exceeded your current quota' => function() {
        $lines = file('a.txt');
        $firstLine = trim($lines[0]);
        $ai_article_gpt_lines = file('ai_article_gpt.php');
        $ai_article_gpt_lines[13] = $firstLine . "\n";
        file_put_contents('ai_article_gpt.php', implode('', $ai_article_gpt_lines));
        array_shift($lines);
        file_put_contents('a.txt', implode('', $lines));
        exit;
    },
    'key is associated with a deactivated account' => function() {
        $lines = file('a.txt');
        $firstLine = trim($lines[0]);
        $ai_article_gpt_lines = file('ai_article_gpt.php');
        $ai_article_gpt_lines[13] = $firstLine . "\n";
        file_put_contents('ai_article_gpt.php', implode('', $ai_article_gpt_lines));
        array_shift($lines);
        file_put_contents('a.txt', implode('', $lines));
        exit;
    }
];

foreach ($keys1 as $keyd1 => $action) {
    if (strpos($$article_gpt, $keyd1) !== false) {
        $action();
        break;
    }
}

优化后的代码：

$keys = [
    'exceeded your current quota' => function() {
        updateArticleGpt();
        exit;
    },
    'key is associated with a deactivated account' => function() {
        updateArticleGpt();
        exit;
    }
];

foreach ($keys as $key => $action) {
    if (strpos($article_gpt, $key) !== false) {
        $action();
        break;
    }
}

function updateArticleGpt() {
    $lines = file('a.txt');
    $firstLine = trim($lines[0]);
    $articleGptLines = file('ai_article_gpt.php');
    $articleGptLines[13] = $firstLine . "\n";
    file_put_contents('ai_article_gpt.php', implode('', $articleGptLines));
    array_shift($lines);
    file_put_contents('a.txt', implode('', $lines));
}

优化后的代码将重复的代码块提取为一个函数updateArticleGpt()，减少了重复代码的冗余。同时，将$keys1重命名为$keys以提高代码的可读性。
