basic array/while question

[foamy]

I've got the following array

$flavors_jn = array
  ('Lamb & Rice','Beef','Variety (Beef, Lamb)');

and I want to loop through it an get the data back out. I've tried using while, to no avail. Basically I don't know wha to put in the [] part. E.g.

while ($flavors_jn)
			{ 
			print "$flavors_jn[]";
			}

gives the error:

Parse error: parse error, expecting T_STRING' orT_VARIABLE' or `T_NUM_STRING'

If I put anything in the [] I get an infinite loop setup.

Here's the output for printr($flavors_jn);

Array ( [0] => Lamb & Rice [1] => Beef [2] => Variety (Beef, Lamb) )

I think I'm close, but I don't have my PHP book with me and this is driving me nuts.

TIA

You could try a different approach, a foreach, or maybe a for loop those are better for printing out all values of an array...

foreach ($array as $value) {
echo "$value<br>";
}

#Or you can...

for($i=0;$i<sizeof($array);$i++) {
echo "$array[$i]<br>";
}

Those would be easier for array looping 🙂

Thanks!

I got it working with

		$a = '1'; $b = count($flavors_jn);
		while ($a <= $b) {
 		$pr = $flavors_jn[$a];
		print "<option value=$pr>$pr</option>";
 			$a++;
		} 

However, I like the foreach method much more. Thanks.

the difference between foreach and while is that foreach will automatically rewind and start at the begining of the array

This is important when looping though arrays as you may not realise that you are not starting at the beginning and so not get all the values you expect.
