How to loop through var1, var2, var3, etc... 1

[mhamilton3]

I have a variable list of paramters that can be passed in to a PHP script. They are var1, var2, var3, etc. I want to use a loop to step through the list and I don't know how to do it.
$i = 0;
do {
print $var$i
if (!$var$i) {
break;
}
}

I want the print statement to print the contents of the variable var1, then the contents of var2, etc. Any help would be greatly appreciated. Thanks

Are the vars an array?

for ($i = 0; $i < count ($arr); $i++) {
echo $arr[$i];
} Regards

Unfortunately the values are not in an array. They are variables that come from a dynamically created page that has 9 different fields listed in sequential order, first1, last1, email1, phone1, etc. I suppose I could enter each name into an array and step through the array (since I know the names), but that means setting up 9 arrays with 9 entries. Is there and easier way. For example Foxpro has the & and the () which will evaluate the contents of a variable so I could dynamically have myvar = 'first' + '$i' and then I could use &myvar or (myvar) to walk through the values.

Sure they're in an array. All form inputs to PHP are in an array: $_GET and $_POST.

for ($counter = 1; $counter <= 9; $counter++)
{
print $_POST['first' . $counter];
print $_POST['last' . $counter];

So have you got the 9 fields appear on the page several times? Regards

Thank you very much sleipnir214! Being new to PHP, I was not aware of this array fact. It is a cool one to know and I think your method will get me where I need to be.
