[PHP] Re: eval

[Bogdan Stancescu]

You can put whatever you want in eval:

<?
  $foo='foo';
  $bar='bar';
  echo("foo is $foo; bar is $bar");
  $myCode='$foo="checking eval statements"; ';
  $myCode.='$bar=str_replace(" ","--",$foo);';
  eval($myCode);
  echo("foo is $foo; bar is $bar");
?>
You could even do this:

<?
  $foo='$i++;';
  $bar='eval($foo);';
  $i=1;
  eval($foo);
  echo("i=$i");
  eval($bar);
  echo("i=$i");
?>

Is it possible to put PHP code in eval ?
Or just vars ?
<?php

$string = 'The result of <?php $a=2; $b=3; $c=$a+$b; echo "$a + $b is $c"; 
?>';

eval ($string);
