无法将PHP变量传递给file_get_contents（）

Question

I am a newbie coder trying to build a simple web app using PHP. I am trying to send an HTML email that has a variable that will change each time it is sent. The code to initiate the email is 'email.php' and contains:

$body = file_get_contents('welcome/green2.html.php');

Within the 'green2.html.php' file, I have a variable called $highlight that needs to be populated. The $highlight variable is defined within the 'email.php' file. I had tried to simply add within the 'green2.html.php' file, however it is not being parsed. I get a blank space where the variable should be when it is output.

Also, I have done an include 'welcome/green2.html.php' within the 'email.php' file. When I echo it, the $highlight var is shown on the resulting page, but not if I echo $body.

Any help would be much appreciated!

Have you tried the str_replace function? http://php.net/manual/en/function.str-replace.php.

Add a placeholder in HTML (for instance #name# for name, #email# for email), and then use the string replace function once you've loaded the content of the file.

$bodytag = str_replace("#name#", $name, $myfile);
