How to write array to file in php_PHP tutorial

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'); } http://www.bkjia.com/PHPjc/629652.html www.bkjia.comtruehttp: //www.bkjia.com/PHPjc/629652.htmlTechArticle provides us with a function var_export in php, which can directly put the php code into a file.
