list to array with defined keys

(1/2) > >>

Anguz:
if I have this


--- Code: ---$list = "
   k1, v1\n
   k2, v2\n
   k3, v3";
--- End code ---

I know that exploding it I can save each line in an array, but how can I use the first value in each line as the key? like this


--- Code: ---'k1' => "v1",
'k2' => "v2",
'k3' => "v3"
--- End code ---

rough thinking of what i came up with, but it keeps adding an empty first element.. i have no idea where it's coming from:


--- Code: ---<?php

$list = "
   k1, v1\n
   k2, v2\n
   k3, v3";

foreach (explode("\n", $list) as $element) {
  $element = trim($element);
  list($key,$value) = explode(",", $element);
  if (!isset($array)) {
    $array = array($key => $value);
  } else {
    $array += array($key => $value);
  }
}

//testing
foreach ($array as $a => $b) {
print "$a - $b\n";
}

?>

--- End code ---

quite simple ;D

replace


--- Code: ---$list = "
   k1, v1\n
   k2, v2\n
   k3, v3";
--- End code ---

with


--- Code: ---$list = "k1, v1\n
   k2, v2\n
   k3, v3";
--- End code ---

and it doesn't happen ;D ;D ;D

Anguz:
aaaa I see... exploding the exploded does the trick

why did you write this line like this?


--- Code: ---$array += array($key => $value);
--- End code ---

the "+=" adds to the existing array instead of overwritting it?

I'm a complete idiot, TOTALLY didn't see that first newline...
