In this paper, an example is given to show that PHP uses OB cache to realize static function. Share it for your reference, as follows:

Implementation steps

1. Create test data table and write data

2. Realize the update operation in the background. Use the OB cache to generate the corresponding HTML file for every 1 content

3. Display the data information of the foreground

Concrete realization

① Create a test data table and write the data (test. sql file): 


# Create a data table 
create table news(
 id int auto_increment,
 title varchar(100) not null default '',
 body text,
 primary key(id)
)engine =myisam default charset=utf8;
# Data writing 
insert into news values(null,' Static ',' Static can reduce server pressure '),(null,' Pseudo static ',' Pseudo-static state can satisfy SEO Optimization ');

② Realize the update operation in the background (admin. php file) 


<?php
 // Specific background updates 
 // Get all the data information 
 mysql_connect('127.0.0.1','root','123456');
 mysql_select_db('test');
 $sql='select * from news';
 $res = mysql_query($sql);
 while ($row=mysql_fetch_assoc($res)) {
 // For each 1 Bar data generation html Documents 
 ob_start();// Open OB Cache 
?>
<!DOCTYPE html>
<html lang="en">
<head>
 <meta charset="utf-8">
 <title> Static introduction </title>
</head>
<body>
 <h1><?php echo $row['title']; ?></h1>
 <div><?php echo $row['body']; ?></div>
</body>
</html>
<?php
 // Get OB Content in the cache 
 $str = ob_get_contents();
 // Shut down OB Cache and empty the contents. Because if you don't empty the browser, you will see all the data results 
 ob_end_clean();
 // Write information to a file   The specific file directory and file name need to be customized 
 // For the real project about html Storage of files  1 Generally, it exists in the format of year, month and day 
 file_put_contents($row['id'].'.html',$str);
}
?>

③ Realize foreground data display (list. php file): 


<?php
 // Show list 
 // Get all the data information 
 mysql_connect('127.0.0.1','root','123456');
 mysql_select_db('test');
 $sql='select * from news';
 $res = mysql_query($sql);
?>
<!DOCTYPE html>
<html lang="en">
<head>
 <meta charset="utf-8">
 <title> Static introduction </title>
</head>
<body>
 <h1> Show list </h1>
 <table>
 <tr>
  <td> Serial number </td>
  <td> Title </td>
  <td> View </td>
 </tr>
 <?php while ($row =mysql_fetch_assoc($res)) {?>
 <tr>
  <td><?php echo $row['id']; ?></td>
  <td><?php echo $row['title']; ?></td>
  <td><a href="<?php echo $row['id'];?>.html" rel="external nofollow" >  View </a></td>
 </tr>
 <?php } ?>
 </table>
</body>
</html>
