Flatten Array To List With Elements?

[jgpippin]

I've got an array that looks like this:

["title"] => "Some Title"
["author"] => 3

and I'm trying to flatten it to a string that looks like this:

title|Some Title|author|3

implode() only displays the values - is there a function to create a list string from an array that includes the element titles?

You could use a [man]foreach/man loop instead:

$string = '';

foreach($array as $key => $value)
    $string .= "$key|$value|";

$string = rtrim($string, '|');

EDIT: Also... welcome to PHPBuilder!

Or a combination of loop and implosion:

$interleaved = array()
foreach($array as $key=>$value)
{
    $interleaved[] = $key;
    $interleaved[] = $value;
}
$string = implode('|', $interleaved);

With the appropriate array functions it could also be done without any loops or intermediate variables, but in my opinion it wouldn't be at all preferable to the above.
