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');
