PHP Function help

[zurih]

I'm trying to add an automated text in $xxx['xxx'] function with a condition.
So baisicly what php code I have to use to add this to a function?

I tried this but its not working

if($xyxy['xyxy']==bla)
{
$xxx['xxx']=$yyy['yyy']." blahblahblah";
} 

I mean that the "blahblahblah" will be the auto text addon to the function when when the condition accures.

Can anyone tell me if the code is good and if not what is the right one?

thanks

no php expert, but it looks right.

if ($variable == "one thing") { // code to do something } 
    else if ($variable == "something else") { // code to do something else } 
    else if ($variable == "yet another thing") { // code to do still something else } 
    else { // default code }

Its ok what u wrote but in "code to do something" I need a code that will add a word to the variable that already excists.

Now what is that code I want to know...

You already posted that code, just use ' instead of " in both instances.

you may not have the variables in scope in the function. use

global $xxx, $yyy; 

also, if your not returning the edited string, you'll need to pass the variables by refrence to the function

function sumfunc(&$xxx, &$yyy) {
    ...
}

Did you surround the "bla" in your if condition with single quotes?
