【PHP】ThinkPHP8数据库迁移示例 以下是一个包含 各种字段类型、约束条件、索引和特殊配置 的ThinkPHP8数据库迁移示例（以products产品表为例），覆盖常见场景：迁移文件示例（database/migrations/20250726153000_create_products_table.php）<?php use think\migration\Migrator; use think\migration\db\Column; class CreateProductsTable extends Migrator { /** * 执行迁移（创建表结构） */ public function change() { // 创建products表，配置表级参数 $table = $this->table('products', [ 'engine' => 'InnoDB', // 数据库引擎 'charset' => 'utf8mb4', // 字符集 'collation' => 'utf8mb4_unicode_ci', // 排序规则 'comment' => '产品表（包含多种字段类型示例）', // 表注释 'auto_increment' => 1000, // 自增ID起始值（MySQL支持） ]); // 字段定义（覆盖各种场景） $table // 1. 自增主键（整数型，无符号，自增） ->addColumn('id', 'integer', [ 'identity' => true, // 自增 'unsigned' => true, // 无符号（只存正数） 'comment' => '产品ID（主键）' ]) // 2. 字符串（有限长度，非空，唯一索引） ->addColumn('sku', 'string', [ 'limit' => 50, // 长度限制 'null' => false, // 非空（默认） 'comment' => '产品SKU（唯一标识）', 'unique' => true // 唯一约束 ]) // 3. 字符串（长文本，可空，带默认值） ->addColumn('name', 'string', [ 'limit' => 255, 'null' => false, 'default' => '', // 默认空字符串 'comment' => '产品名称' ]) // 4. 文本类型（无长度限制，可空） ->addColumn('description', 'text', [ 'null' => true, // 允许为空 'comment' => '产品详细描述' ]) // 5. 小数类型（高精度，带默认值） ->addColumn('price', 'decimal', [ 'precision' => 10, // 总位数 'scale' => 2, // 小数位数 'default' => 0.00, // 默认0.00 'comment' => '产品售价' ]) // 6. 整数类型（无符号，默认值，索引） ->addColumn('stock', 'integer', [ 'unsigned' => true, // 无符号（只存正数） 'default' => 0, // 默认库存0 'comment' => '库存数量', 'index' => true // 普通索引 ]) // 7. 枚举类型（固定可选值） ->addColumn('status', 'enum', [ 'values' => ['draft', 'active', 'disabled'], // 可选值 'default' => 'draft', // 默认草稿状态 'comment' => '产品状态（draft:草稿, active:上架, disabled:下架）' ]) // 8. 布尔类型（tinyint，默认true） ->addColumn('is_recommend', 'boolean', [ 'default' => true, // 默认true（1） 'comment' => '是否推荐（1:是, 0:否）' ]) // 9. 外键关联（整数，无符号，级联操作） ->addColumn('category_id', 'integer', [ 'unsigned' => true, 'null' => false, 'comment' => '所属分类ID', 'index' => true // 普通索引 ]) // 10.

【PHP】PHPExcel 使用手册 PHPExcel 是一个用于操作 Microsoft Excel 格式文件的 PHP 库，它支持读取和写入多种格式（如 .xls, .xlsx, .csv 等）。不过需要注意，PHPExcel 项目已停止维护，推荐使用其继任者 PhpSpreadsheet。以下是 PHPExcel 的基本使用指南：1. 安装 PHPExcel# 使用 Composer 安装（推荐） composer require phpoffice/phpexcel2. 读取 Excel 文件require 'vendor/autoload.php'; use PHPExcel_IOFactory; // 读取文件 $inputFileName = 'example.xlsx'; $objPHPExcel = PHPExcel_IOFactory::load($inputFileName); // 获取第一个工作表 $sheet = $objPHPExcel->getActiveSheet(); // 获取最高行和最高列 $highestRow = $sheet->getHighestRow(); $highestColumn = $sheet->getHighestColumn(); // 遍历数据 for ($row = 1; $row <= $highestRow; $row++) { for ($col = 'A'; $col <= $highestColumn; $col++) { $cellValue = $sheet->getCell($col.$row)->getValue(); echo "Row $row, Column $col: $cellValue\n"; } }3. 创建新的 Excel 文件require 'vendor/autoload.php'; use PHPExcel; use PHPExcel_IOFactory; // 创建新的 PHPExcel 对象 $objPHPExcel = new PHPExcel(); // 设置文档属性 $objPHPExcel->getProperties() ->setCreator("Your Name") ->setTitle("Sample Excel File"); // 获取活动工作表 $sheet = $objPHPExcel->getActiveSheet(); // 设置单元格值 $sheet->setCellValue('A1', 'Hello'); $sheet->setCellValue('B1', 'World!'); $sheet->setCellValue('A2', 'This is a sample spreadsheet.'); // 保存为 .xlsx 文件 $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007'); $objWriter->save('new_file.xlsx');4. 设置样式// 设置字体样式 $sheet->getStyle('A1')->getFont() ->setName('Arial') ->setSize(14) ->setBold(true) ->setColor(new PHPExcel_Style_Color(PHPExcel_Style_Color::COLOR_RED)); // 设置单元格背景色 $sheet->getStyle('A1')->getFill() ->setFillType(PHPExcel_Style_Fill::FILL_SOLID) ->getStartColor()->setARGB('FFEEEEEE'); // 设置对齐方式 $sheet->getStyle('A1')->getAlignment() ->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER) ->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER); // 设置列宽 $sheet->getColumnDimension('A')->setWidth(20);5. 合并单元格// 合并 A1 到 B1 的单元格 $sheet->mergeCells('A1:B1'); // 取消合并 $sheet->unmergeCells('A1:B1');6. 处理日期格式// 设置日期值（PHPExcel 使用 Excel 时间戳格式） $dateTime = new DateTime(); $sheet->setCellValue('A1', $dateTime->format('Y-m-d H:i:s')); // 设置单元格格式为日期 $sheet->getStyle('A1')->getNumberFormat() ->setFormatCode('yyyy-mm-dd hh:mm:ss');7. 保存为不同格式// 保存为 .xlsx 格式 $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007'); $objWriter->save('file.xlsx'); // 保存为 .xls 格式 $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5'); $objWriter->save('file.xls'); // 保存为 CSV 格式 $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'CSV'); $objWriter->save('file.csv');8. 从浏览器下载文件// 设置响应头 header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'); header('Content-Disposition: attachment;filename="download.xlsx"'); header('Cache-Control: max-age=0'); // 输出到浏览器 $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007'); $objWriter->save('php://output'); exit;注意事项性能问题：处理大量数据时，PHPExcel 可能占用较多内存。考虑使用 PHPExcel_CachedObjectStorageFactory 进行优化。替代方案：推荐使用 PhpSpreadsheet，它是 PHPExcel 的官方继任者，修复了许多问题并提供更好的性能。内存优化：// 设置为只读模式以减少内存消耗 $objReader = PHPExcel_IOFactory::createReader('Excel2007'); $objReader->setReadDataOnly(true); $objPHPExcel = $objReader->load('large_file.xlsx');如需更详细的文档，请参考 PHPExcel 官方文档（注意：项目已停止维护）。

【PHP】PHP实现二维数组转一维数组 可以使用 array_reduce() 函数将二维数组转换为一维数组。array_reduce() 函数将通过一个回调函数迭代数组中的所有值，并将它们合并为一个单一的值。在这种情况下，我们将使用 array_merge() 函数将所有子数组合并为一个单一的数组。示例代码如下：function flatten_array($arr) { return array_reduce($arr, function($carry, $item) { return array_merge($carry, is_array($item) ? flatten_array($item) : array($item)); }, array()); } // 测试 $arr = array( array(1, 2, 3), array(4, 5, 6), array( array(7, 8), 9, array(10, 11, 12), ), ); $result = flatten_array($arr); print_r($result); // 输出： // Array // ( // [0] => 1 // [1] => 2 // [2] => 3 // [3] => 4 // [4] => 5 // [5] => 6 // [6] => 7 // [7] => 8 // [8] => 9 // [9] => 10 // [10] => 11 // [11] => 12 // )在上面的示例代码中，我们定义了一个 flatten_array() 函数，该函数使用 array_reduce() 函数和递归调用来将二维数组转换为一维数组。
