parse_pair(string $string): array

Why not parse_str?

Because parse_str works only with a URL query string format.

So foo="bar" will be parsed like

array(1) {
  ["foo"]=>
  string(5) ""bar""
}

We have double-quoted value "bar". Instead, you can use parse_pair and if value is a valid double-quoted it will be expanded

Install

composer require hyqo/pair

Usage

use function Hyqo\Pair\parse_pair;

[$key, $value] = parse_pair('foo="bar"');

echo $key; //foo
echo $bar; //bar

If string is valid, it will be parsed:

string	key	value
foo=	foo	empty string
foo=""	foo	empty string
foo=bar	foo	bar
foo="bar"	foo	bar
foo='bar'	foo	bar
foo="\"bar\""	foo	"bar"
foo="\"bar"	foo	"bar
foo="multi\nline"	foo	multi line
foo='multi\nline'	foo	multi line

If string is invalid, result will be null:

string
foo="bar\"
foo='bar\'
foo="bar""
foo='bar''
