function to count instances of something

Anon

This probably sounds like a stupid question but i can't figure it out. I have a survey that has the old 'strongly agree', 'agree', etc. I have a script that can count each instance of 'strongly agree' or whatever the value. I want to turn it into a function because i need to use it more than one time on a page.

example:

function count(){
if ($variable == "strongly agree"){
$variable_count++;
}
if ($somethingelse == "somethingelse"){
$somethingelse_count++;
}
}
count();

while($this = $that){
count();
}

echo"$variable_count, $somethingelse_count";

Now the trouble I am having is that nothing is echoed out. I suspect no data is going in or coming out of the function. I this case, how would one pass data in or out.

thanks,

Might be several problems here. First one that struck me was the while loop.

while($this = $that){
count();
}

How will this loop ever terminate unless something varies $this or $that? And shouldn't you be comparing $this == $that , not assigning it?

I would also recommend using an array for the answer counts. That way you can just increment the count of each answer.

actually the loop statement was just for example purposes. I actually use the:

while($this = mysql_fetch_array($that)){
}

but the loop isn\'t the area I am having the problem. it\'s the function to count.

I can do it fine without using it as a function.(just copying and pasting the code around) I was just wondering how I could make it a function because I have like 25 variables to increment. And I don\'t like to make my code all messy and bulky when I now I should be able to write function to do it. I was just wondering if anybody had any ideas on how to do this.
