[SOLVED] Reading from a variable instead of a file

[Cenron]

Hey guys I got a quick question that I cant seem to figure out on my own.

 

I want to achieve this

 

         ob_start();
         include($file_path);
         $contents = ob_get_contents();
         ob_end_clean();

 

but I want to load it from a variable instead of a file but I cant think of a way of doing it any idea guys?

[per1os]

         ob_start();
         echo $variable_name;
         $contents = ob_get_contents();
         ob_end_clean();

 

.... I do not know why but that should work...

That did what I wanted it to but I got another problem from it...there is PHP code in the variable and with your method it dosent get parsed it just gets passed as normal text...include parsed it out and displayed only HTML..I am really trying hard from having to write another file with the variable info in it then include.

 

I really do appreciate the help and that was a great idea.

If you have PHP code in a variable that you want to get executed, you need to use the eval() function. Use this function with caution.

eval()

I might just not be doing this the right way

Its still not parsing the PHP even though i run it through the eval.

Here is the code i got so far.

         $temp_content = implode(file($this->html_code));
         $temp_content = str_replace('\\', '\\\\', $temp_content);
         $temp_content = str_replace('\'', '\\\'', $temp_content);
         $stemp_content = explode("\n",$temp_content);

        for($i = 0; $i < sizeof($stemp_content); $i++)
        { $stemp_content[$i] = 'echo \'' . $stemp_content[$i] . '\' . "\\n";'; }

        $temp_content = implode("\n",$stemp_content);

         ob_start();
         echo eval($temp_content);
         $contents = ob_get_contents();
         ob_end_clean();
         return $contents;

         ob_start();
         eval($temp_content);
         $contents = ob_get_contents();
         ob_end_clean();
         return $contents;

 

I do not think you echo eval's.

Ya I got rid of the echo and it still doesn't eval...man this sucks lol

[per1os]

eval is a very touchy, and probably not the best function to use.

 

Most people steer away due to the security issues it causes.

[Cenron]

What do you think would be the best way to achive what I am trying to do?

[per1os]

A template engine like ETS or Smarty or store the template files as well php files.

 

Or you can always create the file for instance:

 

         $temp_content = implode(file($this->html_code));
         $temp_content = str_replace('\\', '\\\\', $temp_content);
         $temp_content = str_replace('\'', '\\\'', $temp_content);
         $stemp_content = explode("\n",$temp_content);

        for($i = 0; $i < sizeof($stemp_content); $i++)
        { $stemp_content[$i] = 'echo \'' . $stemp_content[$i] . '\' . "\\n";'; }

        $temp_content = implode("\n",$stemp_content);

         $filename = 'tempfile' . rand() . time() . '.tpl';
         $fp = fopen($filename, 'w+');
         fwrite($fp, $temp_content);
         fclose($fp);

         ob_start();
         echo eval($temp_content);
         $contents = ob_get_contents();
         ob_end_clean();
         unlink($filename);
         return $contents;

 

just remember the <?php and ?> tags are still required.
