Query String Laravel Package

Fixed

• Fixes an issue introduced in v1.0.2. When creating an instance from string, it's containing an array and the brackets are encoded (like filter%5Bfoo%5D%5B%5D=1&filter%5Bfoo%5D%5B%5D=2), the method trying to fix duplicate keys without brackets added another array level (like filter[foo][] to filter[foo][][]). This is fixed with this release.

Fixed

• Duplicate keys without array notation (like foo=bar&foo=baz) are now also interpreted as array (like foo[]=bar&foo[]=baz). This is considered a bugfix because:
  • Previously foo=bar&foo=baz became foo=baz, which is most likely unwanted behavior.
  • Of course, such query strings should preferably be written using the array notation ([]), but if such a query is written without the brackets, the intention is either that it should be an array, or it's a mistake. If it is a mistake, the probability to notice it is higher, when the result contains all values instead of only the last one.
  • As this library is also part of the crwlr crawling library and there are servers intentionally using the syntax without brackets (e.g. google https://fonts.googleapis.com/css2?family=Baloo&family=Roboto) it's better to interpret it as an array.

Fixed

• When creating a Query from string, and it contains empty key value parts, like &foo=bar, foo=bar& or foo=bar&&baz=quz, the unnecessary & characters are removed in the string version now. For example, &foo=bar previously lead to $instance->toString() returning &foo=bar and now it returns foo=bar.
• To assure that there can't be differences in the array and string versions returned by the Query class, no matter if the instance was created from string or array, the library now first converts incoming values back and forth. So, when an instance is created from string, it first converts it to an array and then again back to a string and vice versa when an instance is created from an array. Some Examples being fixed by this:
  • From string foo=bar :
    • Before: toString(): +++foo=bar++, toArray(): ['foo' => 'bar '].
    • Now: toString(): foo=bar++, toArray(): ['foo' => 'bar ']
  • From string foo[bar] [baz]=bar
    • Before: toString(): foo%5Bbar%5D+%5Bbaz%5D=bar, toArray(): ['foo' => ['bar' => 'bar']].
    • Now: toString(): foo%5Bbar%5D=bar, toArray(): '[foo' => ['bar' => 'bar']].
  • From string foo[bar][baz][]=bar&foo[bar][baz][]=foo
    • Before: toString(): foo%5Bbar%5D%5Bbaz%5D%5B%5D=bar&foo%5Bbar%5D%5Bbaz%5D%5B%5D=foo, toArray(): ['foo' => ['bar' => ['baz' => ['bar', 'foo']]]].
    • Now: toString(): foo%5Bbar%5D%5Bbaz%5D%5B0%5D=bar&foo%5Bbar%5D%5Bbaz%5D%5B1%5D=foo, toArray(): ['foo' => ['bar' => ['baz' => ['bar', 'foo']]]].
  • From string option
    • Before: toString(): option, toArray(): ['option' => '']
    • Now: toString(): option=, toArray(): ['option' => '']
  • From string foo=bar=bar==
    • Before: toString(): foo=bar=bar==, toArray(): [['foo' => 'bar=bar==']
    • Now: toString(): foo=bar%3Dbar%3D%3D, toArray(): [['foo' => 'bar=bar==']
  • From string sum=10%5c2%3d5
    • Before: toString(): sum=10%5c2%3d5, toArray(): [['sum' => '10\\2=5']
    • Now: toString(): sum=10%5C2%3D5, toArray(): [['sum' => '10\\2=5']
  • From string foo=%20+bar
    • Before: toString(): foo=%20+bar, toArray(): ['foo' => ' bar']
    • Now: toString(): foo=++bar, toArray(): ['foo' => ' bar']
• Maintain the correct order of key value pairs when converting query string to array.
