JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,</p> </div> <div class="phphistorical_Version2_mids"> <a href="https://www.php.cn/faq/1796782794.html" title="Explain the concept of late static binding in PHP." class="phphistorical_Version2_mids_img"> <img onerror="this.onerror=''; this.src='/static/imghw/default1.png'" src="/static/imghw/default1.png" class="lazy" data-src="https://img.php.cn/upload/article/202503/21/2025032113332596253.jpg?x-oss-process=image/resize,m_fill,h_207,w_330" alt="Explain the concept of late static binding in PHP." /> </a> <a href="https://www.php.cn/faq/1796782794.html" title="Explain the concept of late static binding in PHP." class="phphistorical_Version2_mids_title">Explain the concept of late static binding in PHP.</a> <span class="Articlelist_txts_time">Mar 21, 2025 pm 01:33 PM</span> <p class="Articlelist_txts_p">Article discusses late static binding (LSB) in PHP, introduced in PHP 5.3, allowing runtime resolution of static method calls for more flexible inheritance.Main issue: LSB vs. traditional polymorphism; LSB's practical applications and potential perfo</p> </div> <div class="phphistorical_Version2_mids"> <a href="https://www.php.cn/faq/1796786130.html" title="Framework Security Features: Protecting against vulnerabilities." class="phphistorical_Version2_mids_img"> <img onerror="this.onerror=''; this.src='/static/imghw/default1.png'" src="/static/imghw/default1.png" class="lazy" data-src="https://img.php.cn/upload/article/202503/28/2025032817115475121.jpg?x-oss-process=image/resize,m_fill,h_207,w_330" alt="Framework Security Features: Protecting against vulnerabilities." /> </a> <a href="https://www.php.cn/faq/1796786130.html" title="Framework Security Features: Protecting against vulnerabilities." class="phphistorical_Version2_mids_title">Framework Security Features: Protecting against vulnerabilities.</a> <span class="Articlelist_txts_time">Mar 28, 2025 pm 05:11 PM</span> <p class="Articlelist_txts_p">Article discusses essential security features in frameworks to protect against vulnerabilities, including input validation, authentication, and regular updates.</p> </div> <div class="phphistorical_Version2_mids"> <a href="https://www.php.cn/faq/1796787536.html" title="How to send a POST request containing JSON data using PHP's cURL library?" class="phphistorical_Version2_mids_img"> <img onerror="this.onerror=''; this.src='/static/imghw/default1.png'" src="/static/imghw/default1.png" class="lazy" data-src="https://img.php.cn/upload/article/001/246/273/174269580466138.jpg?x-oss-process=image/resize,m_fill,h_207,w_330" alt="How to send a POST request containing JSON data using PHP's cURL library?" /> </a> <a href="https://www.php.cn/faq/1796787536.html" title="How to send a POST request containing JSON data using PHP's cURL library?" class="phphistorical_Version2_mids_title">How to send a POST request containing JSON data using PHP's cURL library?</a> <span class="Articlelist_txts_time">Apr 01, 2025 pm 03:12 PM</span> <p class="Articlelist_txts_p">Sending JSON data using PHP's cURL library In PHP development, it is often necessary to interact with external APIs.

Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.</p> </div> <div class="phphistorical_Version2_mids"> <a href="https://www.php.cn/faq/1796791139.html" title="How does session hijacking work and how can you mitigate it in PHP?" class="phphistorical_Version2_mids_img"> <img onerror="this.onerror=''; this.src='/static/imghw/default1.png'" src="/static/imghw/default1.png" class="lazy" data-src="https://img.php.cn/upload/article/001/253/068/174386897193010.jpg?x-oss-process=image/resize,m_fill,h_207,w_330" alt="How does session hijacking work and how can you mitigate it in PHP?" /> </a> <a href="https://www.php.cn/faq/1796791139.html" title="How does session hijacking work and how can you mitigate it in PHP?" class="phphistorical_Version2_mids_title">How does session hijacking work and how can you mitigate it in PHP?</a> <span class="Articlelist_txts_time">Apr 06, 2025 am 12:02 AM</span> <p class="Articlelist_txts_p">Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.</p> </div> </div> <a href="https://www.php.cn/be/" class="phpgenera_Details_mainL4_botton"> <span>See all articles</span> <img src="/static/imghw/down_right.png" alt="" /> </a> </div> </div> </div> </main> <footer> <div class="footer"> <div class="footertop"> <img src="/static/imghw/logo.png" alt=""> <p>Public welfare online PHP training，Help PHP learners grow quickly！</p> </div> <div class="footermid"> <a href="https://www.php.cn/about/us.html">About us</a> <a href="https://www.php.cn/about/disclaimer.html">Disclaimer</a> <a href="https://www.php.cn/update/article_0_1.html">Sitemap</a> </div> <div class="footerbottom"> <p> © php.cn All rights reserved </p> </div> </div> </footer> <input type="hidden" id="verifycode" value="/captcha.html"> <script>layui.use(['element', 'carousel'], function () {var element = layui.element;$ = layui.jquery;var carousel = layui.carousel;carousel.render({elem: '#test1', width: '100%', height: '330px', arrow: 'always'});$.getScript('/static/js/jquery.lazyload.min.js', function () {$("img").lazyload({placeholder: "/static/images/load.jpg", effect: "fadeIn", threshold: 200, skip_invisible: false});});});</script> <script src="/static/js/common_new.js"></script> <script type="text/javascript" src="/static/js/jquery.cookie.js?1744781822"></script> <script src="https://vdse.bdstatic.com//search-video.v1.min.js"></script> <link rel='stylesheet' id='_main-css' href='/static/css/viewer.min.css?2' type='text/css' media='all' /> <script type='text/javascript' src='/static/js/viewer.min.js?1'></script> <script type='text/javascript' src='/static/js/jquery-viewer.min.js'></script> <script type="text/javascript" src="/static/js/global.min.js?5.5.53"></script> <script> var _paq = window._paq = window._paq || []; /* tracker methods like "setCustomDimension" should be called before "trackPageView" */ _paq.push(['trackPageView']); _paq.push(['enableLinkTracking']); (function () { var u = "https://tongji.php.cn/"; _paq.push(['setTrackerUrl', u + 'matomo.php']); _paq.push(['setSiteId', '9']); var d = document, g = d.createElement('script'), s = d.getElementsByTagName('script')[0]; g.async = true; g.src = u + 'matomo.js'; s.parentNode.insertBefore(g, s); })(); </script> <script> // top layui.use(function () { var util = layui.util; util.fixbar({ on: { mouseenter: function (type) { layer.tips(type, this, { tips: 4, fixed: true, }); }, mouseleave: function (type) { layer.closeAll("tips"); }, }, }); }); document.addEventListener("DOMContentLoaded", (event) => { // 定义一个函数来处理滚动链接的点击事件 function setupScrollLink(scrollLinkId, targetElementId) { const scrollLink = document.getElementById(scrollLinkId); const targetElement = document.getElementById(targetElementId); if (scrollLink && targetElement) { scrollLink.addEventListener("click", (e) => { e.preventDefault(); // 阻止默认链接行为 targetElement.scrollIntoView({ behavior: "smooth" }); // 平滑滚动到目标元素 }); } else { console.warn( `Either scroll link with ID '${scrollLinkId}' or target element with ID '${targetElementId}' not found.` ); } } // 使用该函数设置多个滚动链接 setupScrollLink("Article_Details_main1L2s_1", "article_main_title1"); setupScrollLink("Article_Details_main1L2s_2", "article_main_title2"); setupScrollLink("Article_Details_main1L2s_3", "article_main_title3"); setupScrollLink("Article_Details_main1L2s_4", "article_main_title4"); setupScrollLink("Article_Details_main1L2s_5", "article_main_title5"); setupScrollLink("Article_Details_main1L2s_6", "article_main_title6"); // 可以继续添加更多的滚动链接设置 }); window.addEventListener("scroll", function () { var fixedElement = document.getElementById("Article_Details_main1Lmain"); var scrollTop = window.scrollY || document.documentElement.scrollTop; // 兼容不同浏览器 var clientHeight = window.innerHeight || document.documentElement.clientHeight; // 视口高度 var scrollHeight = document.documentElement.scrollHeight; // 页面总高度 // 计算距离底部的距离 var distanceToBottom = scrollHeight - scrollTop - clientHeight; // 当距离底部小于或等于300px时，取消固定定位 if (distanceToBottom <= 980) { fixedElement.classList.remove("Article_Details_main1Lmain"); fixedElement.classList.add("Article_Details_main1Lmain_relative"); } else { // 否则，保持固定定位 fixedElement.classList.remove("Article_Details_main1Lmain_relative"); fixedElement.classList.add("Article_Details_main1Lmain"); } }); </script> </body> </html>
