【Elasticsearch】IK 分词器安装指南和PHP使用实例 IK 分词器安装指南是的，IK 分词器需要单独安装。 Elasticsearch 默认只提供标准分词器，对于中文分词效果不佳，IK 分词器是专门针对中文优化的分词插件。一、IK 分词器安装方法方法 1：手动安装（推荐）步骤 1：下载对应版本的 IK 分词器# 进入 Elasticsearch 插件目录 cd /www/server/elasticsearch/plugins # 创建 ik 目录 mkdir ik cd ik # 下载对应版本的 IK 分词器 # 注意：版本号必须与 Elasticsearch 版本一致！ # 查看 ES 版本：curl -X GET "localhost:9200/" wget https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.17.0/elasticsearch-analysis-ik-7.17.0.zip # 解压 unzip elasticsearch-analysis-ik-7.17.0.zip # 删除 zip 文件 rm -f elasticsearch-analysis-ik-7.17.0.zip # 返回插件目录上级，确保目录结构正确 cd .. ls -la ik/步骤 2：重启 Elasticsearch# 通过宝塔面板重启 # 或者使用命令 systemctl restart elasticsearch步骤 3：验证安装# 验证 IK 分词器是否安装成功 curl -X GET "localhost:9200/_cat/plugins?v" # 测试分词效果 curl -X POST "localhost:9200/_analyze" -H 'Content-Type: application/json' -d' { "analyzer": "ik_smart", "text": "中华人民共和国" }'正常响应：{ "tokens" : [ { "token" : "中华人民共和国", "start_offset" : 0, "end_offset" : 7, "type" : "CN_WORD", "position" : 0 } ] }方法 2：使用 Elasticsearch 插件命令安装# 进入 Elasticsearch 安装目录 cd /www/server/elasticsearch # 使用插件管理器安装 ./bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.17.0/elasticsearch-analysis-ik-7.17.0.zip # 重启 Elasticsearch systemctl restart elasticsearch二、宝塔面板特有的安装方法通过宝塔终端操作打开宝塔面板 → 终端执行安装命令：# 切换到 elasticsearch 用户（宝塔环境可能需要） sudo -u elasticsearch /bin/bash # 进入 ES 插件目录 cd /www/server/elasticsearch/plugins # 下载并安装 IK 分词器 wget https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.17.0/elasticsearch-analysis-ik-7.17.0.zip unzip elasticsearch-analysis-ik-7.17.0.zip -d ik rm -f elasticsearch-analysis-ik-7.17.0.zip # 退出 elasticsearch 用户 exit # 重启 Elasticsearch 服务 systemctl restart elasticsearch宝塔文件管理器操作下载 IK 分词器：访问 IK 分词器 Releases下载对应版本的 ZIP 文件通过宝塔文件管理器上传：进入 /www/server/elasticsearch/plugins/创建 ik 文件夹上传 ZIP 文件到 ik 文件夹解压并删除 ZIP 文件重启服务：宝塔面板 → 软件商店 → Elasticsearch → 重启三、IK 分词器版本对应关系Elasticsearch 版本IK 分词器版本7.17.x7.17.07.16.x7.16.07.15.x7.15.07.14.x7.14.07.13.x7.13.07.12.x7.12.07.11.x7.11.07.10.x7.10.07.9.x7.9.0重要：必须确保版本一致，否则 Elasticsearch 无法启动！四、验证安装的完整脚本<?php /** * IK 分词器验证脚本 * 保存为 test_ik.php 并在浏览器访问 */ require '/www/wwwroot/your-site/vendor/autoload.php'; use Elasticsearch\ClientBuilder; class IKValidator { private $client; public function __construct() { $this->client = ClientBuilder::create() ->setHosts(['localhost:9200']) ->build(); } /** * 检查 IK 分词器是否安装 */ public function checkIKInstallation() { echo "<h2>IK 分词器安装验证</h2>"; // 1. 检查插件列表 echo "<h3>1. 已安装插件列表</h3>"; try { $plugins = $this->client->cat()->plugins(['v' => true]); echo "<pre>"; foreach ($plugins as $plugin) { echo $plugin .

【PHP】bc系列函数（高精度数学运算） PHP bc系列函数（高精度数学运算）简介：bc系列函数用于处理任意精度的十进制计算，适用于金融、科学计算等对精度要求极高的场景。需启用bcmath扩展（可通过phpinfo()检查是否启用）。特点：所有参数和返回值均为字符串类型（避免精度丢失）支持自定义小数位数（scale参数）提供基本运算、比较、幂运算等完整功能一、基础运算函数1. 加法：bcadd()// 语法：bcadd(左操作数, 右操作数, 保留小数位数) echo bcadd('123.456', '78.9', 2); // 202.36（123.456 + 78.9 = 202.356，保留2位小数） echo bcadd('100', '200', 0); // 300（整数相加）2. 减法：bcsub()// 语法：bcsub(被减数, 减数, 保留小数位数) echo bcsub('100.5', '30.25', 1); // 70.2（100.5 - 30.25 = 70.25，保留1位小数） echo bcsub('50', '75', 0); // -25（负数结果）3. 乘法：bcmul()// 语法：bcmul(乘数1, 乘数2, 保留小数位数) echo bcmul('2.5', '4.2', 2); // 10.50（2.5 × 4.2 = 10.5，保留2位小数） echo bcmul('100', '0.01', 0); // 1（整数与小数相乘）4. 除法：bcdiv()// 语法：bcdiv(被除数, 除数, 保留小数位数) echo bcdiv('10', '3', 3); // 3.333（10 ÷ 3 ≈ 3.3333...，保留3位） var_dump(bcdiv('5', '0', 0)); // false（除数为0时返回false）5. 取模（余数）：bcmod()// 语法：bcmod(被除数, 除数) echo bcmod('10', '3'); // 1（10 ÷ 3 余数为1） echo bcmod('7.5', '2.5'); // 0.0（7.5 是 2.5 的整数倍）二、比较函数bccomp()// 语法：bccomp(值1, 值2, 比较精度) // 返回值：1（值1 > 值2）、0（相等）、-1（值1 < 值2） echo bccomp('10', '10', 0); // 0（相等） echo bccomp('10.5', '10.49', 1); // 1（10.5 > 10.49，精确到1位小数） echo bccomp('5.999', '6', 2); // -1（5.999 < 6，精确到2位小数）三、幂运算与开方1. 幂运算：bcpow()// 语法：bcpow(底数, 指数, 保留小数位数) echo bcpow('2', '3', 0); // 8（2³ = 8） echo bcpow('1.2', '2', 2); // 1.44（1.2² = 1.44）2. 幂运算取模：bcpowmod()// 语法：bcpowmod(底数, 指数, 模数, 保留小数位数) // 作用：(base^exponent) % modulus，比先算幂再取模更高效 echo bcpowmod('3', '3', '5', 0); // 2（3³=27，27%5=2）3. 开平方：bcsqrt()// 语法：bcsqrt(数值, 保留小数位数) echo bcsqrt('25', 0); // 5（√25 = 5） echo bcsqrt('2', 4); // 1.4142（√2 ≈ 1.4142，保留4位） var_dump(bcsqrt('-4', 0)); // false（负数无法开平方）四、全局配置函数bcscale()// 功能：设置所有bc函数的默认小数位数（全局生效） bcscale(2); // 全局默认保留2位小数 echo bcadd('1', '2'); // 3.00（使用全局配置） echo bcsub('5', '3.5'); // 1.50（自动补全2位小数） echo bcadd('1', '2', 0); // 3（局部参数优先级高于全局）关键注意事项参数类型：必须传入字符串（如'123.45'），而非数字（避免自动转换导致精度丢失）。返回值：始终为字符串，需转换类型时用(float)或(int)。扩展依赖：需在php.ini中启用extension=bcmath（重启服务生效）。精度优先级：函数的scale参数 > bcscale()全局配置。通过这些函数，PHP可以实现高精度计算，解决普通数值类型精度不足的问题。

【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）。
