#4091 — implode() order?

How can I specify the order that an Array() is imploded?  See code below:

[code]
<?php
$toImplode = Array(
	1 => "Second", 
	0 => "First", 
	2 => "Third"
);

$finalString = implode(" - ", $toImplode);

echo "<p>" . $finalString . "</p>";

/* Results as "Second - First - Third"
 * But I need it to be "First - Second - Third"
 */
?>
[/code]

#4092

The actual code uses named keys:

[code]
$toImplode = Array(
  "b" => "Second",
  "a" => "First",
  "c" => "Third"
);
[/code]

Do a ksort( $toImplode ); before the implode. (See 
http://de.php.net/manual/en/function.ksort.php)

Thanks... suppose the keys are not in a sortable order, like this:

$toImplode = Array(
  "second" = "Second",
  "fourth" = "Fourth",
  "third" = "Third",
  "first" = "First"
);

Or would I need to simply:

echo $toImplode["first"] . $toImplode["second"]; // etc.

Use usort() and define your own comparison function.

Or you could just use the individual elements as you indicated.  There 
is no rule you have to use implode().

Rather u*k*sort() for sorting by keys:
http://de3.php.net/manual/en/function.uksort.php

See the marked part.

You should also post the (manual) URI that works best for the person using 
it, which would be

  <http://php.net/uksort>

in this case.

This is not PHP code.

No, aside from u(k)sort() you can use a loop to build a new array:

  $a = array();

  foreach (array('first', 'second', 'third', 'fourth') as $key)
  {
    $a[] = $toImplode[$key];
  }

  echo implode(',', $a);
