Can I execute PHP code from a MySQL variable?

[gargoyle1]

I have a few lines like this:

if (something){
 print str_replace($array_values, $array_variables, $section_code);
  }
else {
  do something else}

everything fetches and prints from the DBase just fine until I have something like 'echo $somestring;' in the retrieved code.

instead of printing 'whatever the string is' it prints 'echo whatever the string is'

do I need to replace the php commands somehow?

do you want to replace them or have them parsed?

you could use
[php.net...]

use the eval() function to evaluate the string as PHP code.

Ultimately, I want the code that is in the MySQL field to be executed on the current page, variables and all.

Until this point, I was simply replacing variables because I didn't need to use code.

I have a situation now that is easily solved if I can store some PHP with variables inside the code, and let it execute at certain times.

I basically need one statement that execute the whole thing, variables, and code when needed. If I can execute the whole thing as code without having to worry about replacing the variables, thats fine too.

the eval() function isn't working properly, which is why I opted to use the str_replace.

Let me rephrase that.. I'M having trouble using it properly. I'm sure it's working just fine ;)

$somestring = 'whatever the string is';
$content = 'echo $somestring;';
eval($content);

I've been messing with it for about half an hour now rewriting things where necesary. It's working intermittently, but I'm confident that I can make it work totally.

I've been using eval($somestring);

How different is that from the method that you suggested where I echo $somestring into $content, and eval ($content)?

mine is just an example since I am not going to build a table, store some code in a col and then select and eval it ;)

so i threw some php code into a var and eval'ed the var, that's all I wanted to show you.

You just eval whatever the var is where you have the code selected from the column in your db.

Cool, I seem to have figured it out with your help. Thanks a million for your prompt responses.

I think that the problem here is that I'm building a script that is so complex that when I look at it from too wide an angle, I have no idea wth I'm doing. LOL
