PHP - split String in Key/Value pairs

问题

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?

回答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);

回答2:

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

回答3:

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

回答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.
