如何获取php文件的html生成内容而不是包含该文件

I want to make a cms which generates html pages and creates files to store each page.

Ideally i need something like that:

<?php
$file1 = get_produced_html_from('mainPage.php');
/* write the file to a directory*/


$file2 = get_produced_html_from('ProductsPage.php');
/* write the file to a directory*/
?>

Is there any function i missed instead of require, include, require_once, include_onse etc?

To clarify: I don't need the php code inside the .php file. I need the html content only which means that the php file should be executed first.

Do you believe the solution is something like using http://php.net/manual/en/function.file-get-contents.php by reading http://domain.com/templates/mainPage.php as a html stream?

Thank you a lot.

You need to catch the output from the buffer.

Here is a piece of code I wrote for somebody to demonstrate a very simple view renderer class.

public function render($file) {
    $file = $this->viewPath = APP_ROOT . 'View' . DS . $file . '.php';
    if (is_file($file)) {
        ob_start();
        extract($this->_vars);
        include($file);
        $content = ob_get_contents();
        ob_end_clean();
    } else {
        throw new RuntimeException(sprintf('Cant find view file %s!', $file));
    }

    return $content;
}

It turns on the output buffer (ob_start()) executes the php file and sets the variables and then gets the buffer (ob_get_contents()) and then it cleans the buffer for the next operation (ob_end_clean()). You can also use ob_end_flush() to directly clean and send the buffer. I would not do that and instead do a proper shutdown process of the app and ensure everything is done and was done right without errors before sending the page to the client.

I think I'm going to make the whole code available on Github soon. I'll update the answer then.

You can just use cURL to get the whole rendered output from an url.

You can use it like this:

// Initiate the curl session
$ch = curl_init();

// Set the URL
curl_setopt($ch, CURLOPT_URL, 'http://www.example.com/mypage.php');

// Allow the headers
curl_setopt($ch, CURLOPT_HEADER, true);

// Return the output instead of displaying it directly
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Execute the curl session
$output = curl_exec($ch);

// Close the curl session
curl_close($ch);
