Implode / Explode PHP array

Question

I'm trying to manipulate an $array:

Array ([0] => General [1] => Custom Title) 

Using Implode, I can get the $array into individual pieces seperated by a space:

<?php $pieces = implode(" ", $array); ?>

Output:

General Custom Title

However, if the array pieces are two words, it doesn't work as I would prefer the output to be:

General Custom-Title

Any ideas?

Answer 1

Replace spaces with hyphens, before you implode.

foreach ($arr as $idx => $val) {
    $arr[$idx] = str_replace(" ", "-", $val);
}
$pieces = implode(" ", $arr);

Answer 2

You have to use some string manipulation function for this. I suggest a combination of str_replace with either array_walk (or array_map ) or a simple foreach loop.

Answer 3

<?php 
foreach ($myArray as $key => $value) {
    $myArray[$key] = str_replace(' ' , '-', $value);
}
$output = implode(' ', $myArray);
?>

Answer 4

$x = array('Hallo X', 'Hallo Y');

echo implode(' ', (array_map(function($e) { return str_replace(' ', '-', $e); }, $x)));

Answer 5

A one liner. The flaw is that you may have %% in the elements of your array, but I doubt that.

$pieces = str_replace('%%', ' ', str_replace(' ', '-', implode('%%', $array)));
