    Welcome to My Website<\/h1>\n This line was generated with PHP!<\/p>\";\n ?>\n<\/body>\n<\/html><\/pre>

    This lets you dynamically generate content based on conditions, user input, or database queries. Just remember, anything outside<\/strong> the <\/code> tags is treated as plain HTML or text.<\/p>

    Also worth noting: if your file starts and ends with PHP code only, you can skip the closing ?><\/code> tag. It's optional and sometimes even preferred to leave it out to avoid accidental whitespace issues.<\/p>

    Mix Dynamic Content Seamlessly<\/h3>

    You can switch back and forth between PHP and HTML multiple times in one file. That's super handy when you want to build dynamic pages without repeating yourself.<\/p>

    Here's how you might conditionally show different HTML blocks:<\/p>

    					<p>You can embed PHP code into HTML files, but make sure that the file is with .php as the extension so that the server can parse it correctly. Use the standard <?php and ?> tags to wrap PHP code, insert dynamic content anywhere in HTML. In addition, you can switch PHP and HTML multiple times in the same file to realize dynamic functions such as conditional rendering. Be sure to pay attention to the server configuration and syntax correctness to avoid problems caused by short labels, quotation mark errors or omitted end labels. </p>
    <p><img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/175052525382924.jpg" class="lazy" alt="How do I embed PHP code in an HTML file?"></p>
    <p> You can absolutely embed PHP code in an HTML file — and it's a common practice when building dynamic websites. The key is to make sure the file is processed by the server as PHP, which usually means saving it with a <code>.php</code> extension instead of <code>.html</code> . Once that's set up, you can drop PHP anywhere in your HTML using the right tags.</p>
    <h3 id="Use-the-Right-File-Extension"> Use the Right File Extension</h3>
    <p> If you want to mix PHP and HTML, start by saving your file with a <code>.php</code> extension. For example: <code>index.php</code> instead of <code>index.html</code> . This tells the server to parse the file for PHP code before sending it to the browser.</p>
    <p> Most hosting providers are already configured to handle <code>.php</code> files, so this step alone usually does the trick. If you're working locally (like with XAMPP or MAMP), just make sure Apache or Nginx is properly configured to process PHP files.</p>
    <h3 id="Embed-PHP-Inside-HTML-with-Proper-Tags"> Embed PHP Inside HTML with Proper Tags</h3>
    <p> To insert PHP into your HTML, use the standard opening and closing PHP tags: <code><?php </code> and <code>?></code> . Anything between these tags will be executed as PHP code.</code></p>
    <p> For example:</p><pre class='brush:php;toolbar:false;'> <!DOCTYPE html>
    <html>
    <head>
        <title>My PHP Page</title>
    </head>
    <body>
        <h1>Welcome to My Website</h1>
        <?php
            echo "<p>This line was generated with PHP!</p>";
        ?>
    </body>
    </html></pre><p> This lets you dynamically generate content based on conditions, user input, or database queries. Just remember, anything <strong>outside</strong> the <code><?php ... ?></code> tags is treated as plain HTML or text.</p><p> Also worth noting: if your file starts and ends with PHP code only, you can skip the closing <code>?></code> tag. It's optional and sometimes even preferred to leave it out to avoid accidental whitespace issues.</p><h3 id="Mix-Dynamic-Content-Seamlessly"> Mix Dynamic Content Seamlessly</h3><p> You can switch back and forth between PHP and HTML multiple times in one file. That's super handy when you want to build dynamic pages without repeating yourself.</p><p> Here's how you might conditionally show different HTML blocks:</p><pre class='brush:php;toolbar:false;'> <?php $showWelcome = true; ?>
    
    <!DOCTYPE html>
    <html>
    <head><title>Mixing PHP and HTML</title></head>
    <body>
    
    <?php if ($showWelcome): ?>
        <h2>Hello, visitor!</h2>
    <?php else: ?>
        <h2>Welcome back!</h2>
    <?php endif; ?>
    
    </body>
    </html></pre><p> This approach keeps your logic and layout tightly connected but still readable. Just make sure your PHP syntax is clean and well-structured, especially when jumping in and out of HTML.</p>
    <h3 id="Watch-Out-for-Server-Setup-and-Syntax-Errors"> Watch Out for Server Setup and Syntax Errors</h3>
    <p> Even if your code looks perfect, it won't run unless the server is set up to interpret PHP. If you see your PHP code printed on screen or commented out in the source, the server isn't parsing it — double-check your file extension and server configuration.</p>
    <p> Also, always validate your PHP syntax. A missing semicolon or unclosed quote can break the whole page.</p>
    <p> A few common gotchas:</p>
    <ul>
    <li> Using short tags like <code></code> or <code>=</code> , which may not be enabled on all servers.</li>
    <li> Mixing single and double quotes incorrectly inside echoed strings.</li>

    								<p class="Articlelist_txts_p">Upgrading the PHP version is actually not difficult, but the key lies in the operation steps and precautions. The following are the specific methods: 1. Confirm the current PHP version and running environment, use the command line or phpinfo.php file to view; 2. Select the suitable new version and install it. It is recommended to install it with 8.2 or 8.1. Linux users use package manager, and macOS users use Homebrew; 3. Migrate configuration files and extensions, update php.ini and install necessary extensions; 4. Test whether the website is running normally, check the error log to ensure that there is no compatibility problem. Follow these steps and you can successfully complete the upgrade in most situations.</p>

Call exit() after redirecting in conjunction with header() to prevent subsequent code execution; In addition, exit() can accept string parameters as output content or integers as status code, and its alias is die().</p>

For index arrays or only deduplication, use array_merge and array_unique combinations: first merge array_merge($array1,$array2) and then use array_unique() to deduplicate them to finally get a new array containing all unique values; 2. For associative arrays and want to retain key-value pairs in the first array, use the operator: $result=$array1 $array2, which will ensure that the keys in the first array will not be overwritten by the second array.

    								<p class="Articlelist_txts_p">Recursive functions refer to self-call functions in PHP. The core elements are 1. Defining the termination conditions (base examples), 2. Decomposing the problem and calling itself recursively (recursive examples). It is suitable for dealing with hierarchical structures, disassembling duplicate subproblems, or improving code readability, such as calculating factorials, traversing directories, etc. However, it is necessary to pay attention to the risks of memory consumption and stack overflow. When writing, the exit conditions should be clarified, the basic examples should be gradually approached, the redundant parameters should be avoided, and small inputs should be tested. For example, when scanning a directory, the function encounters a subdirectory and calls itself recursively until all levels are traversed.</p>
