In PHP, we are provided with a function var_export, which can directly import PHP code into a file.

The code is as follows
 代码如下 复制代码

var_export($times,true);后面不加true不能写入文件哟
$fp = fopen('aa.txt','w+');
fwrite($fp,var_export($times,true));
fclose($fp);

Copy code

var_export($times,true); the file cannot be written without adding true at the end
$fp = fopen('aa.txt','w+');
fwrite($fp,var_export($times,true));
fclose($fp);

 代码如下 复制代码

if(isset($_POST['sub'])){    
 $cfg = array('contact'=>$_POST['contact']); //把数据存入数组   
 file_put_contents('./data/contact.cache',serialize($cfg));
        //把数组序列化之后,写到contact.cache里,
 $this->redirect('other/contact');//跳转
 }
 else{    
 $fp = fopen('./data/contact.cache','r');//读
 $cf = unserialize(fread($fp,filesize('./data/contact.cache')));//反序列化,并赋值
 $this->assign('cfg',$cf);//送到前台模板
 $this->display('other/contact');
 }

Method 2

Use serializ and unserialize functions

The code is as follows Copy code
if(isset($_POST['sub'])){ 
$cfg = array('contact'=>$_POST['contact']); //Save data into array
file_put_contents('./data/contact.cache',serialize($cfg));
//After serializing the array, write it into contact.cache,
$this->redirect('other/contact');//Jump
}
else{ 
$fp = fopen('./data/contact.cache','r');//read
$cf = unserialize(fread($fp,filesize('./data/contact.cache')));//Deserialize and assign value
$this->assign('cfg',$cf);//Send to the front desk template
$this->display('other/contact');

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
