二维数组 PHP
这个是一个效果演示,有的黑色分类 右边有一个 小图标 new 或者 hot
可以通过下面这个设置来控制 哪个分类要显示 new 或者 hot
比如第一组分类的 第二个 链接 要显示 新 图标,那后台设置 1:2
第二组分类 第一个链接 要显示 new 在 后台设置 2:1 这样来控制
foreach($jsonArray as $i=>$i$jsonObject){ //输出一级分类 echo '分组链接'; foreach($array as $k=>$id) { //输出二级分类,二级分类有些需要设置图标,获取了用户设置的参数,怎么来判断哪个子分类要添加图标,然后在那个分类输出图片class echo '该分组下的子链接'; } }
如果用户只设置了一个 比如 1:2 我还会判断 ,可是比如 设置new图标的分类有 1:2,2:4,3:2 三个子分类
我就不知道php怎么写了
回复讨论(解决方案)
1:2 的情况你是如何写的
<?php$setting_clsss = array( 'blod'=>'5:3,1:2', 'new1' => '4:2', 'new2' => '2:2',);// 处理成array(行=>array(列=>class))的结构$row_class = array();foreach($setting_clsss as $key => $value) { if(strpos($value, ',') === false) { $value .=','; } foreach(explode(',', $value) as $class) { if(!$class) continue; list($row, $column) = explode(':', $class); $row_class[$row][$column] = $key; // 多个可以用数组表示 }}$links = array( array(1, 2), array(1, 2), array(1, 2), array(1, 2), array(1, 2, 3),);foreach($links as $row=>$link){ //输出一级分类 $row += 1; //从0开始so+1 echo '分组链接', $row, ' : '; foreach($link as $column=>$id) { //输出二级分类,二级分类有些需要设置图标,获取了用户设置的参数,怎么来判断哪个子分类要添加图标,然后在那个分类输出图片class $column += 1; //从0开始so+1 echo '连接', $column; if(isset($row_class[$row][$column])) { echo '-',$row_class[$row][$column]; } echo ' '; } echo "\n";}
$ar = array( 'blod'=>'5:3,1:2', 'new1' => '4:2', 'new2' => '2:2',);foreach($ar as $k=>$r) { foreach(array_chunk(preg_split('/[,:]/', $r), 2) as $v) echo "$k : $v[0]行$v[1]列\n";}blod : 5行3列
blod : 1行2列
new1 : 4行2列
new2 : 2行2列
把 preg_split('/[,:]/', $r) 写成
preg_split('/\D+/', $r)

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.

Key players in HTTP cache headers include Cache-Control, ETag, and Last-Modified. 1.Cache-Control is used to control caching policies. Example: Cache-Control:max-age=3600,public. 2. ETag verifies resource changes through unique identifiers, example: ETag: "686897696a7c876b7e". 3.Last-Modified indicates the resource's last modification time, example: Last-Modified:Wed,21Oct201507:28:00GMT.

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.
