I have a awkward need but I need to interleave an array with another array before imploding the result. I guess my better option would be less talk more example
Array number one
[0] => "John has a ", [1] => "and a", [2] => "!"
Array number two
[0] => 'Slingshot", [1] => "Potato"
I need to produce
John has a Slingshot and a Potato!
My question is can I do that with an implode or I must build my own function?
Simple Solution
$a = [0 => "John has a", 1 => "and a", 2 => "!" ];
$b = [0 => "Slingshot", 1 => "Potato"];
vsprintf(implode(" %s ", $a),$b);
Use array_map before implode
$a = [0 => "John has a", 1 => "and a", 2 => "!" ];
$b = [0 => "Slingshot", 1 => "Potato"];
$data = [];
foreach(array_map(null, $a, $b) as $part) {
$data = array_merge($data, $part);
}
echo implode(" ", $data);
Another Example :
$data = array_reduce(array_map(null, $a, $b), function($a,$b){
return array_merge($a, $b);
},array());
echo implode(" ", $data);
Both Would output
John has a Slingshot and a Potato !

Adapted from comment above.
Are you sure you don't just want string formatting?
echo vsprintf("John has a %s and a %s!", array('slingshot', 'potato'));
Output:
John has a slingshot and a potato!
echo vsprintf() -- if you are going to print it with echo then you should more directly just call vprintf().Might be worth looking at the top answer on Interleaving multiple arrays into a single array which seems to be a slightly more general (for n arrays, not 2) version of what otherwise exactly what you're after :-)
$a = [0 => "John has a ", 1 => "and a", 2 => "!" ];
$b = [0 => "Slingshot", 1 => "Potato"];
foreach($a AS $k=>$v){
echo trim($v).' '.trim($b[$k]).' ';
}
If you fix your spaces so they're consistent :)
You'd also want to add an isset() check too probably.
trim would be useful here for the space also.$b[$k] Is not guaranteed to exist.
