[SOLVED] Parse error

[The Little Guy]

I have this:

eval("echo '<h1>'.$calc.'</h1>';");

 

and it gives me this:

 

Parse error:  syntax error, unexpected T_DNUMBER, expecting ',' or ';' in /home/.marble/ryannaddy/dudeel.com/results/toolsCalculator.php(18) : eval()'d code on line 1

Do you get the same thing with this?

eval('echo "<h1>".$calc."</h1>";');

[rhodesa]

is there a reason you are eval()ing the code?

 

what is the value of $calc? remember, the value of $calc will be substituted before the eval.

[The Little Guy]

ah... got it!

 

eval("echo '<h1>'.($calc).'</h1>';");

[rhodesa]

any reason for the eval instead of just:

echo '<h1>'.($calc).'</h1>';

[The Little Guy]

yes, because if the user types in 2+2, it displays 2+2, using the eval it displays 4

[rhodesa]

ah. well, just be careful on security there since you are giving the user control to run ANY php code

[The Little Guy]

Im trying to write something that will remove php functions/code unless it is a math function

[rhodesa]

hence the question in the other post....gotchya
