正则表达式 - 如何用 php 抓取微信文章正文？
php
微信
正規表示式
我是一个新手，想使用php抓取微信页面的正文和标题，标题直接用正则表达式|<title>(.*?)|i</title>就抓取到了，但是正文我想的是|>(.*?)匹配标签间的内容，再去掉空格，但是还是会匹配到一堆标签，是怎么回事？或者说有其他更好的方法吗？求指教！

回复内容：
我是一个新手，想使用php抓取微信页面的正文和标题，标题直接用正则表达式|<title>(.*?)<\/title>|i就抓取到了，但是正文我想的是|>(.*?)<\/|i匹配标签间的内容，再去掉空格，但是还是会匹配到一堆标签，是怎么回事？或者说有其他更好的方法吗？求指教！

PHP和Python：比較兩種流行的編程語言
Apr 14, 2025 am 12:13 AM
PHP和Python各有優勢，選擇依據項目需求。 1.PHP適合web開發，尤其快速開發和維護網站。 2.Python適用於數據科學、機器學習和人工智能，語法簡潔，適合初學者。
PHP行動：現實世界中的示例和應用程序
Apr 14, 2025 am 12:19 AM
PHP在電子商務、內容管理系統和API開發中廣泛應用。 1)電子商務：用於購物車功能和支付處理。 2)內容管理系統：用於動態內容生成和用戶管理。 3)API開發：用於RESTfulAPI開發和API安全性。通過性能優化和最佳實踐，PHP應用的效率和可維護性得以提升。
PHP：網絡開發的關鍵語言
Apr 13, 2025 am 12:08 AM
PHP是一種廣泛應用於服務器端的腳本語言，特別適合web開發。 1.PHP可以嵌入HTML，處理HTTP請求和響應，支持多種數據庫。 2.PHP用於生成動態網頁內容，處理表單數據，訪問數據庫等，具有強大的社區支持和開源資源。 3.PHP是解釋型語言，執行過程包括詞法分析、語法分析、編譯和執行。 4.PHP可以與MySQL結合用於用戶註冊系統等高級應用。 5.調試PHP時，可使用error_reporting()和var_dump()等函數。 6.優化PHP代碼可通過緩存機制、優化數據庫查詢和使用內置函數。 7
PHP的持久相關性：它還活著嗎？
Apr 14, 2025 am 12:12 AM
PHP仍然具有活力，其在現代編程領域中依然佔據重要地位。 1)PHP的簡單易學和強大社區支持使其在Web開發中廣泛應用；2)其靈活性和穩定性使其在處理Web表單、數據庫操作和文件處理等方面表現出色；3)PHP不斷進化和優化，適用於初學者和經驗豐富的開發者。
PHP和Python：代碼示例和比較
Apr 15, 2025 am 12:07 AM
PHP和Python各有優劣，選擇取決於項目需求和個人偏好。 1.PHP適合快速開發和維護大型Web應用。 2.Python在數據科學和機器學習領域佔據主導地位。
PHP與其他語言：比較
Apr 13, 2025 am 12:19 AM
PHP適合web開發，特別是在快速開發和處理動態內容方面表現出色，但不擅長數據科學和企業級應用。與Python相比，PHP在web開發中更具優勢，但在數據科學領域不如Python；與Java相比，PHP在企業級應用中表現較差，但在web開發中更靈活；與JavaScript相比，PHP在後端開發中更簡潔，但在前端開發中不如JavaScript。
PHP和Python：解釋了不同的範例
Apr 18, 2025 am 12:26 AM
PHP主要是過程式編程，但也支持面向對象編程（OOP）；Python支持多種範式，包括OOP、函數式和過程式編程。 PHP適合web開發，Python適用於多種應用，如數據分析和機器學習。
PHP：處理數據庫和服務器端邏輯
Apr 15, 2025 am 12:15 AM
PHP在數據庫操作和服務器端邏輯處理中使用MySQLi和PDO擴展進行數據庫交互，並通過會話管理等功能處理服務器端邏輯。 1）使用MySQLi或PDO連接數據庫，執行SQL查詢。 2）通過會話管理等功能處理HTTP請求和用戶狀態。 3）使用事務確保數據庫操作的原子性。 4）防止SQL注入，使用異常處理和關閉連接來調試。 5）通過索引和緩存優化性能，編寫可讀性高的代碼並進行錯誤處理。
