Question for Pro?

im using eval to parse the php code.
example:
eval ('?>' . $template_design . '<?');
but how can i parse the php code without displaying it and then return the value in a string using return statment.

I think you can create a variable inside the eval(), e.g.

eval("<? $string = some php code; ?>");

and then after the eval() you can use $string.

my $design string gets from the database and here is what $design contain:

$design = " HTML Code..... <? echo $my_data.'lots of php code...?> Html code.... and more of PHP Code...";

here is the code i use to parse php and html, but how can i save the output in a string for the return statment?
code i use:

eval ("?> $design <?");

are you pro 🆒 ?
Please Help me in this one, because i really need to parse the code without echoing it.

sijis

so you want to store what eval() will evaluate?

i think you can do this:

$non_eval = eval ("?> $design <?");
then
return $non_eval;
from your function.

Please Help me in this one.

sijis

well. i don't have a coded solution, but i can give you direction.

http://www.php.net/manual/en/function.eval.php
in there it says

Tip: As with anything that outputs its result directly to the browser, you can use the output-control functions to capture the output of this function, and save it in a string (for example).

output-control functions
http://www.php.net/manual/en/ref.outcontrol.php

The following code example is from the reference manual...

ob_start(); // Start output buffering
eval( substr( $string, $pos + 2, $pos2 - $pos - 2) ); // Eval statements...
$value = ob_get_contents(); // Get the output buffer
ob_end_clean(); // Erase the buffer. You can also flush itto the screen.

can you type little example of out-Control function, because some how php.net site wont open, i think its the mirror that they are useing, but any way can you please type little example here?

sbehnke you solve my problem and thank both of you for helping me out thanks again. you guys took me to next level in programming in php and can you tell me if there is any site like php.net to see the full references of the functions just like php.net, because i moved to different country and i could open the php.net faster before when i came here but now i can hardly open front page only, i think its there mirror that they are using and the mirror hosting called "web host talking" something like that. so thats why i need to find some other site to look into the references of php code.

It might be slow to download the entire manual, but you only have to download once:
