eval() function

Hi.
Does the PHP eval() function work in a similar way the javascript version?

I have the following function:
function altercolour($colour1, $colour2, $colour3) {
}
If the value “green” is given to $colour1, I want to perform alterations to the variable $green, and if “blue” is submitted the function would alter $blue…. etc.

Is this possible with eval(), in a similar way to javascript? Or can anyone suggest a better way to do this?

@redijediJul 11.2004 — I'm not quite sure what you mean by your example, but eval() lets you evaluate a string as if it were php code.

From php manual:

[code=php]
$string = 'cup';
$name = 'coffee';
$str = 'This is a $string with my $name in it.';
echo $str. "n";
eval("$str = "$str";");
echo $str. "n";
[/code]

Returns:

This is a $string with my $name in it.

This is a cup with my coffee in it.
