Problems with eval

[shadowk]

Description:

" In case of a parse error in the evaluated code, eval() returns FALSE.
In case of a fatal error in the evaluated code, the whole script exits."

Reproduce code:

$page  = 'for(\$i=0;\$i<=2;\$i++){?>';  

$page .= '<b>test code</b>';  

$page .= '<? } ?>';  

$cad = $page;  

$cad = @eval($cad)==false ? echo $cad : ob_get_contents();  

Expected result:

$cad should be $cad='<b>test code</b><b>test code</b><b>test code</b>'

Actual result:

$cad is echod to the screen

and don't tell me not to use echo, because i want to output something if the eval() fails.
Why doesn't this work?

I'm not sure if I got the point but you might try this:

  

$page  = 'fr(\$i=0;\$i<=2;\$i++){?>';  

$page .= '<b>test code</b>';  

$page .= '<? } ?>';

ob_start();
if (@eval($page) === false)
  echo 'Error'; 
else $cad = ob_get_contents(); 
ob_end_flush();

Why are you trying to escape the $ sign?

Your already using single quotes, which will mean the text will be put in literally.
