Is there a php command to take a specific field from a delimited line of text?

Hi,

I have a string which is multiple fields delimited by commas.

I would like a php command that says... take the 3rd field for
example.

ie. If MYVARIABLE has the data "hello,there,big,world".

I would like to be able to say, pickup the 3rd field "big" without
knowing the character positions or lengths.

Any help would be much appreciated.

Thanks.

Tino

<?php
$MYVARIABLE = 'hello,there,big,world';

#Method 1
$fields = explode(',', $MYVARIABLE);
//3rd field is now in $fields[2];

#Method 2
$tok = strtok($MYVARIABLE, ',');
$count = 0;
while($tok){
$count++;
if($count == 3){
$thirdfield = $tok;
break;
}
$tok = strtok(',');
}
?>
