#12093 — foreach as list

foreach ($six0 as list($a,$b)){
  echo $a"\n";
  echo $b"\n";
  
}

http://us1.php.net/manual/en/control-structures.foreach.php

Used as shown in the example, I get this:
Parse error: syntax error, unexpected T_LIST, expecting '&' or T_STRING or
T_VARIABLE or '$

Their example:

<?php
$array = [
    [1, 2],
    [3, 4],
];

foreach ($array as list($a)) {
    // Note that there is no $b here.
    echo "$a\n";
}
?>

The above example will output:

1
3

This feature is only available since PHP 5.5.0 (as noted in the manual)
-- which version do you use?

Well phooey.
Looks like hostgator doesn't have php 5.5.
Which I need to use "as list".

  echo $a"\n"; [needs a dot.]

Actually, in the case, richard is correct (for this line of code, 
anyway).  Simple variables within double quotes are evaluated.

However as typical for richard he mistyped his code compared to the sample.

Sample:  "$a\n"
Richards: $a"\n"

Ah, you're right, Scotty.  I was looking at the last part of his code, 
figuring it was similar to the first part.  With Richard, I should have 
known better.

No, you don't. If you get that, then you didn't use it as shown in the example.

Which means that you didn't use it as shown in the example.
