渲染Php文件然后将其作为html返回[关闭]

I'm trying to render a php file and then return it as html to send in an email, how would I go about doing this? Here is an example of the code that I'm using:

public function setPHP($php)
{
    ob_start();
    $phpsend = ( include $php );
    $this->html = (string) ob_get_contents();
    ob_end_clean();
}

Here is how I'm calling the function.

    $php = file_get_contents( NHM_PLUGIN_DIR . 'assets/templates/newhomesguide.php' );
    $css = file_get_contents( NHM_PLUGIN_DIR . 'assets/css/email_template.css' );

    $cssToInlineStyles->setPHP($php);
    $cssToInlineStyles->setCSS($css);

I'm trying to modify CSSToInlineStyles by Tijs Verkoyen, which inlines css with html, I'm just trying do do the same but with a php file that has functionality.

I think you're pretty close. This is how I would do it. The evaluated file will be in $this->html like you want and it will immediately be sent to the output stream after being evaluated.

public function setPHP($php)
{
    if(!file_exists($php)) // Some error handling here maybe?
      die('File ' . $php . ' DNE');

    // Eval the $php file and store it in a variable
    ob_start();
    include $php;
    $this->html = ob_get_clean();

    // Send the evaluated file to the output stream
    echo $this->html;
}
