PHP - split String in Key/Value pairs

Question

I have a string like this:

key=value, key2=value2

and I would like to parse it into something like this:

array(
  "key" => "value",
  "key2" => "value2"
)

I could do something like

$parts = explode(",", $string)
$parts = array_map("trim", $parts);
foreach($parts as $currentPart)
{
    list($key, $value) = explode("=", $currentPart);
    $keyValues[$key] = $value;
}

But this seems ridiciulous. There must be some way to do this smarter with PHP right?

Answer 1

If you don't mind using regex ...

$str = "key=value, key2=value2";
preg_match_all("/([^,= ]+)=([^,= ]+)/", $str, $r); 
$result = array_combine($r[1], $r[2]);
var_dump($result);

Answer 2

<?php parse_str(str_replace(", ", "&", "key=value, key2=value2"), $array); ?>

Answer 3

if you change your string to use & instead of , as the delimiter, you can use parse_str()

Answer 4

If you can change the format of the string to conform to a URL query string (using & instead of ,, among other things, you can use parse_str. Be sure to use the two parameter option.

Answer 5

Here's a single command solution using array_reduce formatted in multple lines for readability:

<?php
$str = "key=value, key2=value2";
$result = array_reduce(
   explode(',', $str), 
   function ($carry, $kvp) {
      list($key, $value)=explode('=', $kvp); 
      $carry[trim($key)]=trim($value); 
      return $carry;
    }, []);
