[PHP] Eval To String

[Shaun]

Hi,

Is it possible to return the result of eval function to a string rather than 
outputting directly to the browser?

Thanks for your advice

Yes.

You're welcome.

The first freakin' example in TFM http://www.php.net/eval is this;

?php
$string = 'cup';
$name = 'coffee';
$str = 'This is a $string with my $name in it.';
echo $str. \n;
eval(\$str = \$str\;);
echo $str. \n;
?

ob_start();
eval('$eval = evil;');
$output = ob_get_clean();

here is an example:

$php_code = "$foo + $bar";
eval("\$var = \"$php_code\";);

now in $var there should be the eval of $foo + $bar

Hi,

 I want to evaluate the code in $php_code to *another* string...

you have to do it through output buffering:

  ob_start();
  eval($php_code);
  $another_string=ob_get_contents();
  ob_end_clean();

From

http://www.php.net/manual/en/function.eval.php :

"A return statement will terminate the evaluation of the string
immediatley. In PHP 4 you may use return to return a value that will
become the result of the eval() function while in PHP 3 eval() was of
type void and did never return anything."

So, if you're using PHP4, just ensure that there is a return
in$php_code that returns the desired value:

$thing = eval($php_code);

It's helpful to read the notes at the above URL - escaping things
correctly for eval() can be tricky...
