*HELP!!!* Simple PHP Echo error! Need quick help Please!

Alright, i have no idea why this isn't working.


I have this in a php script (a function):


echo rating_bar('177');

The above works 100% FINE, but now instead of "177" i'm adding a php variable... (it's a digit also...)

echo rating_bar('$picid');

where $picid = "177";

but it appears as "Picture id: $picid" when it should be "Picture id: 177"




Please help asap! It's a matter of making echo rating_bar('$picid'); ECHO the variable instead of just showing the text.


Thanks SO much to whoever helps, you will get +rep ofcourse

 

Did you try echo rating_bar($picid); or echo rating_br("$picid");

What shallowink said. Variables such as $picid do not get expanded to their value when placed inside single quotes, only double quotes. You don't really need any quotes at all though since you're only sending that one though, can just place the variable itself.
