Implementation method of accounting tree menu in ComboTree of ThinkPHP+EasyUI
The following editor will bring you an article on how to implement the accounting tree menu in ComboTree of ThinkPHP+EasyUI. The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let’s follow the editor to take a look.
Assume that the fields of the accounting data table in the database are: id, code, name, islast. They are the auto-increment primary key, account code, account name, and whether it is the last-level account ("1" indicates the last-level account).
Here, recursion is used in the model layer of Thinkphp to build the data required by ComboTree. The code and annotations are as follows:
namespace Home\Model;
use Think\Model;
class AccountModel extends Model{
public function getTreeList(){
$data = $this->field('id,code,name,islast')->select();
foreach($data as &$v){ //这里加入了元素pid，用来标识父级id的
$len = strlen($v['code']);
if($len == 3){ //这里假设长度为3位的科目编码是一级,5位为二级科目，7位为三级，以此类推
$v['pid'] = 0;
} else {
$v['pid'] = substr($v['code'],0,$len-2);
}
}
return $this->createTree($data); //生成ComboTree所需的数据结构
}
//递归的方式生成子树
private function createSubTree($data,$pid){
$tree = array();
foreach($data as $k=>$v){
if($v['pid'] == $pid){
$newDate = array(
'id' => $v['id'],
'text'=>$v['name'],
'state'=>($v['islast'] != 1)?'closed':'open'
);
if($v['islast'] != 1){ //如果不是末级科目调用自身生成子数据
$subData = $this->createSubTree($data,$v['code']);
if(!empty($subData)){
$newDate['children'] = $subData;
}
}
array_push($tree,$newDate);
}
}
return $tree;
}
//生成树,先从一级会计科目分类开始创建树形菜单数据
private function createTree($data){
$ret = array();
foreach($data as $k => $v){
if($v['pid'] == 0){
$newDate = array( //创建为ComboTree能够识别的格式，这里我没有更好的办法了，只能这样处理
'id' => $v['id'],
'text'=>$v['name'],
'state'=>'closed'
);
$subData = $this->createSubTree($data,$v['code']);
if(!empty($subData)){
$newDate['children'] = $subData;
}
$ret[] = $newDate;
}
}
return $ret;
}
}Data similar to the above (such as departments, regions, etc.) can basically achieve similar functions by simply modifying the code to build a tree menu.

PHP and Python: Comparing Two Popular Programming Languages
Apr 14, 2025 am 12:13 AM
PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.
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.
PHP in Action: Real-World Examples and Applications

PHP: A Key Language for Web Development
Apr 13, 2025 am 12:08 AM
PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7
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.
