Simple Variable Syntax Question.

[blackberryoctopus]

I am receiving 40 variables from an external source into my php script.
I need to have for loop cycle through those and assign them to
variables in the php script. I am unsure of the syntax, but it would be
something like the following

for($i=0;$i<40; $i++){
$phpvar+$i = receivedData+$i
}


The data coming in is named as follows data1, data2, data3, ... data40.
So I need the php variables to be named in the same way. Whats the
syntax here? Thanks for any help.

But it would make more sense to create an array:

$data = array();
for ( ... ){
$data[] = receivedData+$i ;
}

Data coming in from where? GET? POST? Command line? Cookies? Let's
suppose it's POST and you have POST variables named data1, data2, ...
data40. Then it would be something like this:

for($i = 1; $i <= 40; $i++) {
$name = "data$i";
$$name = $_POST[$name];
}

Or you could use extract

extract($_POST) ;

Or you could just use the array elements directly

echo $_POST['data1'];

Re: Simple Variable Syntax Question.

There is a shorter way I think. If we assume those are POST variables, the
code might look something like

foreach ($_POST as $name =$value)
$name = $value;

I know that referencing the elements directly would work, but it would
be cumbersome and in flexible for future revisions. I am trying to
avoid this; so some sort of for loop to populate an array or multiple
variables in php seemed like the best way.

Re: Simple Variable Syntax Question.

I definately would suggest you to use array, as advised in the first
post. Dynamic variable -names are usually result of bad design.

Nearly.

foreach ($_POST as $name =$value){
$$name = $value;
}

Yep, I saw it as well and hoped someone would correct.

Thanks.
