Interpreting a txt file that contains php vars

Copy linkTweet thisAlerts:
Aug 20.2021

I have a good chunk of html and text in a separate fie that I am reading in to my script using file_get_contents. It also contains some php vars. This file is then output to the screen using a heredocs wrapper. The problem is that the heredocs is not translating the php vars into their values.

How does one accomplish this kind of thing?

[code=php]
eval("echo <<<EODn".file_get_contents($the_file)."nEOD;");
[/code]
...but I hate using eval() if I don't really have to. :|

I shall think more about it over lunch....

Yeah, as long as you don't have to worry about something in the middle of it having text like...
<i>
</i>text text text
EOD;
exec('rm -fr .');
exit;

...you should be fine.

  • - Altering those files to actually be included PHP file, where it's basically just one command: $text = "lots of $stuff here...";, then in the main script
    [code=php]
     include 'path/to/the/file';
    echo $text;
    [/code]

  • - Assuming it's a well-defined set of possible variables/replacements, use str_replace() or preg_replace() to explicitly set each such occurrence.
    [code=php]
    $replacements = [
    '$foo' => $foo,
    '$bar' => $bar
    ];
    $echo str_replace(array_keys($replacements), $replacements, file_get_contents('the_file.txt'));
    [/code]


    • I'm not jumping with joy for either of those, so... 🤷‍♂️

    @ginerjmauthorAug 20.2021 — It's a structured HTML document that I want to add blocks of <Ii> tags to as they come to me. I figured it was easy to modify the text file rather than the php one. Since I am the only who can access it I'm not worried about hacking. And it's not that important anyway.

    The eval thingie will work just fine for me.

    Thx again.
