【PHP】PHP函数详解：call_user_func()使用方法 PHP函数详解：call_user_func()使用方法 call_user_func函数类似于一种特别的调用函数的方法，使用方法如下： <?php function nowamagic($a,$b) { echo $a; echo $b; } call_user_func('nowamagic', "111","222"); call_user_func('nowamagic', "333","444"); //显示 111 222 333 444 ?> 调用类内部的方法比较奇怪，居然用的是array，不知道开发者是如何考虑的，当然省去了new，也挺有新意的： <?php class a { function b($c) { echo $c; } } call_user_func(array("a", "b"),"111"); //实例化a类并调用b方法 //显示 111 ?> call_user_func_array函数和call_user_func很相似，只不过是换了一种方式传递了参数，让参数的结构更清晰： <?php function a($b, $c) { echo $b; echo $c; } call_user_func_array('a', array("111", "222")); //显示 111 222 ?> call_user_func_array函数也可以调用类内部的方法的 <?php Class ClassA { function bc($b, $c) { $bc = $b + $c; echo $bc; } } call_user_func_array(array('ClassA','bc'), array("111", "222")); //显示 333 ?> call_user_func函数和call_user_func_array函数都支持引用，这让他们和普通的函数调用更趋于功能一致： <?php function a($b) { $b++; } $c = 0; call_user_func('a', $c); echo $c;//显示 1 call_user_func_array('a', array($c)); echo $c;//显示 2 ?> 另外，call_user_func函数和call_user_func_array函数都支持引用。 <?php function increment(&$var) { $var++; } $a = 0; call_user_func('increment', $a); echo $a; // 0 call_user_func_array('increment', array(&$a)); // You can use this instead echo $a; // 1 ?>

【Layui】图片预览 要在 layui 中点击图片实现预览功能，你可以使用 layui 的 layer.photos 方法来轻松实现图片预览。以下是如何在点击图片时使用 layer.photos 来创建图片预览的示例代码：<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>Layui Image Preview</title> <link rel="stylesheet" href="path/to/layui/css/layui.css"> <script src="path/to/layui/layui.js"></script> </head> <body> <div class="images-container"> <img class="preview-image" src="path/to/image1.jpg" alt="Image 1"> <img class="preview-image" src="path/to/image2.jpg" alt="Image 2"> <img class="preview-image" src="path/to/image3.jpg" alt="Image 3"> </div> <script> layui.use(['layer'], function() { var layer = layui.layer; // 点击事件处理 $('.preview-image').on('click', function() { var images = []; // 存放图片信息的数组 var currentImage = this.src; // 获取所有图片信息 $('.preview-image').each(function() { images.push({ alt: $(this).attr('alt'), src: $(this).attr('src') }); }); // 在弹窗中预览图片 layer.photos({ photos: { title: '图片预览', // 弹窗标题 data: images, start: images.findIndex(img => img.src === currentImage) // 从当前图片开始预览 }, shadeClose: true, // 点击遮罩关闭弹窗 closeBtn: 2 // 显示关闭按钮 }); }); }); </script> </body> </html> 在上述示例代码中，我们创建了一个包含多个图片的容器，然后为每个图片添加了共同的类名 preview-image。通过点击图片，会触发 layer.photos 方法，该方法可以用来创建一个图片预览弹窗。我们使用一个包含图片信息的数组来配置预览图片，其中 title 为弹窗标题，data 包含图片信息，start 指定从数组中的哪个索引开始预览。请注意，替换代码中的图片 URL 和其他相关信息。此示例为演示目的，你可以根据实际需求进行调整和修改。

【PHP】php.ini如何配置，才是PHP性能最大优化？ 内存 默认设置memory_limit = 128M单个进程可使用的内存最大值，这个值的设定可以从以下几点考虑：应用的类型。如果是内存集中型应用，可增加该值；单个 PHP 进程平均消耗的内存，该值可通过多次运行同一个脚本来计算平均值；能负担多少个 php-fpm 进程；该值等于分配的总内存除以单个 PHP 进程平均消耗的内存文件上传 默认设置file_uploads = On max_file_uploads = 20 upload_max_filesize = 2M max_execution_time = 30 值 为 0 代表没有限制设置max_file_uploads来决定同时允许多少个文件上传；设置upload_max_filesize来决定每个文件上传的最大值；如果是长时间任务，尽量使用队列来处理，因此，可适当缩短max_execution_time的值；注意， Web 服务器也可以设置文件上传大小及超时时间，不能仅仅以 php.ini 的设置为准；会话 PHP 的会话默认是保存在硬盘中session.save_handler = files在实际应用中，应当将会话保存在内存中。可使用 Memcached 或者 Redis。这样做主要有两个好处：提高速度；有助于后期的扩展，如果会话数据存储在硬盘中，不便于增加额外的服务器，如果把会话数据存放在 Memcached 或 Redis 里，任何一台分布式 PHP-FPM 服务器都能访问会话数据。可通过 PECL 安装memcached扩展并设置默认的save_handler为memcachedsession.save_handler = 'memcached' session.save_path = '127.0.0.1:11211'缓冲输出 默认值realpath_cache_size = 4M realpath_cache_ttl = 120PHP 会缓存应用使用的文件路径，这样每次包含或导入文件时就无需不断搜索包含路径了，这个缓存叫真实路径缓存（realpath cache），如果运行的是大型的 PHP 文件（如 Composer 组件），使用了大量文件，增加 PHP 真实路径缓存的大小能得到更好的性能。

【Redis】解决redis远程连接不上的问题 redis现在的版本开启redis-server后，redis-cli只能访问到127.0.0.1，因为在配置文件中固定了ip，因此需要修改redis.conf（有的版本不是这个文件名，只要找到相对应的conf后缀的文件即可）文件以下几个地方。1.bind 127.0.0.1改为 #bind 127.0.0.1 (注释掉)2.protected-mode yes 改为 protected-mode no3.加入 daemonize no(这个是是否在后台启动不占用一个主程窗口)
