HomeBackend DevelopmentPHP Tutorial有一个二维数组 不知道怎么写

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)
更具普遍性

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

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.

How does PHP handle object cloning (clone keyword) and the __clone magic method?How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AM

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 vs. Python: Use Cases and ApplicationsPHP vs. Python: Use Cases and ApplicationsApr 17, 2025 am 12:23 AM

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.

Describe different HTTP caching headers (e.g., Cache-Control, ETag, Last-Modified).Describe different HTTP caching headers (e.g., Cache-Control, ETag, Last-Modified).Apr 17, 2025 am 12:22 AM

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.

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?Apr 17, 2025 am 12:06 AM

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.
