PHP implements scheduled generation of HTML website homepage example code_PHP tutorial

Before we start, let’s mention three functions: "ob_start(), ob_end_clean(), ob_get_contents()"
ob_start(): opens the buffer, which is to cache the content of the static file you need to generate in Here;
ob_get_contents(): is to read the contents of the buffer. The following code is an example;
ob_end_clean(): This is more important. Only after using this function, the contents of the buffer will be read. Take it out;

Copy code The code is as follows:

if(file_exists("./index.htm"))// Check whether the static index.htm file exists
{
time=time();
//If the file modification time is different from the current time?, direct to the htm file, otherwise regenerate the htm
if( time-filemtime("./index.htm")< 600)
{
header("Location:classhtml/main.htm");
}
}
//in Add ob_start() at the beginning;
ob_start();
//The content of the home page is your dynamic part
//Add ob_end_clean() at the end, and output this page to a variable Medium
temp=ob_get_contents();
ob_end_clean();
//Write file
fp=fopen("./index.htm",'w');
fwrite( fp,temp) or die('Error writing file');
//echo "Generating HTML completed!";
