Custom function that echoes a text

[nic0las]

Hi,
Look at this script :

function addopt($opt)
{
echo "$opt";
}


echo "blah blah: ".addopt("stuff")."";

As you can see, this is a simple custom function, that echoes the text passed to it. But the problem is that this text isn't displayed where it should be, that is to say, where the call to the function is made.
It outputs this :

"stuffblah blah: "

Instead of this :

"blah blah: stuff"

Could someone explain me why, and how to get around this?
Thanks.

Hi,

try following:

function addopt($opt){
  return "$opt";
}

echo "blah blah: ".addopt("stuff")."";

I guess that's because you can't use [FONT=courier new]echo[/FONT] inside [FONT=courier new]echo[/FONT].
For your example [FONT=courier new]addopt("blah blah: stuff");[/FONT] should work.

Is that because the function is evaluated first in the expression? And since that is the case it is given to output first then the rest of the expression is evaluated.
