如何在不使用eval的情况下解析文件 - PHP？

Is there any other way to parse the file without eval()? I'm trying to render the php code without using php tags inside index.gs and so far i can do it only with eval(). The problem is not only to parse vars, but custom template characters.

here is the sample of code below.

 $render = file_get_contents($this->file);

 $render = $this->parse_extends($render);
 $render = $this->parse_assets($render);
 $render = $this->parse_vars($render);
 $render = $this->parse_vars_skip($render);

  try {
        ob_start();
        eval('?>' . $render);
        $render = ob_get_contents();
    } finally {
        ob_get_clean();
    }
    return $render;

The return $render - return to View::class code for response

If the allow_url_include directive is enabled in php.ini, then it’s possible to execute this code using

include "data://text/plain;base64," . base64_encode($render);

but this setting is disabled by default, and cannot be changed within user code, but only through editing the php.ini file; so unless explicitly enabled in php.ini (and there normally isn’t any good reason why it should be), then it isn’t really an option.

An alternative is to create a temporary file, write the code there, and then execute it using include:

$tempFilename = tempnam("/tmp", "MyTemplate");
file_put_contents($tempFilename, $render);
include $tempFilename;
unlink($tempFilename);

But both have similar issues and dangers to eval().
