php
function generateDescription($title, $keywords) {

深度内容生成系统

文章结构生成器

php
function generateArticleStructure($title, $keywords) {
$kwList = explode(',', $keywords);
$structure = [
'引言' => "每到春季，{$kwList[0]}就成为关注焦点...",
'核心部分' => [],
'总结' => "综上所述，{$kwList[0]}需要特别注意..."
];

// 动态生成3-5个核心段落
$corePoints = [
    "{$kwList[0]}的基本原理",
    "常见的{$kwList[1]}误区",
    "专业{$kwList[0]}技巧"
];

foreach ($corePoints as $point) {
    $structure['核心部分'][] = [
        '小标题' => $point,
        '内容' => generateParagraph($point)
    ];
}

return $structure;

}

段落生成逻辑

php
function generateParagraph($topic) {
$sentences = [
"关于{$topic}，业内专家普遍认为...",
"实际操作中，我们发现{$topic}存在几个关键点...",
"根据2023年最新数据显示，{$topic}的应用效果提升显著...",
"要真正掌握{$topic}，需要从三个方面入手..."
];

shuffle($sentences);
return implode(' ', array_slice($sentences, 0, 3));

}

完整内容输出示例

php
// 从CSV读取原始数据
$rawData = arraymap('strgetcsv', file('input.csv'));

// 处理并生成内容
$processedData = [];
foreach ($rawData as $item) {
$processedData[] = [
'标题' => generateTitle($item[1]),
'关键词' => formatKeywords($item[1]),
'描述' => generateDescription($item[0], $item[1]),
'正文' => generateFullArticle($item[0], $item[1])
];
}

// 输出到新CSV文件
$output = fopen('articles.csv', 'w');
fputcsv($output, array_keys($processedData[0]));
foreach ($processedData as $row) {
fputcsv($output, $row);
}
fclose($output);

性能优化建议

1. 内存管理：处理大文件时使用SplFileObject
   php $file = new SplFileObject('large.csv'); while (!$file->eof()) { $row = $file->fgetcsv(); // 处理逻辑 }

2. 批量处理：每1000行数据保存一次进度php
   $batchSize = 1000;
   $output = fopen('result.csv', 'w');
   $input = fopen('source.csv', 'r');

$count = 0;
while (($row = fgetcsv($input)) !== false) {
$processed = processRow($row);
fputcsv($output, $processed);

if (++$count % $batchSize === 0) {
    fflush($output); // 强制写入磁盘
}

}

1. 编码处理：自动检测文件编码
   php function detectEncoding($filePath) { $content = file_get_contents($filePath); return mb_detect_encoding($content, ['UTF-8', 'GBK', 'BIG5'], true); }
