Explode string with brackets and without brackets

I have values that look like this...

{X}{Y}{Z}{R}{R}

I have 2 questions, first question, how can I explode it so the resulting array looks like this...

Array
(
    [0] => {X}
    [1] => {Y}
    [2] => {Z}
    [3] => {R}
    [4] => {R}
)

And the second question is, how can I explode it like this...

Array
(
    [0] => X
    [1] => Y
    [2] => Z
    [3] => R
    [4] => R
)

All you need is :

$str = "{X}{Y}{Z}{R}{R}" ;
preg_match_all("/\{([A-Z])\}/", $str,$matches);
print_r($matches);

See Live DEMO

Array
(
    [0] => Array
        (
            [0] => {X}
            [1] => {Y}
            [2] => {Z}
            [3] => {R}
            [4] => {R}
        )

    [1] => Array
        (
            [0] => X
            [1] => Y
            [2] => Z
            [3] => R
            [4] => R
        )

)

Explanation

This uses the regular expression \{([A-Z])\}. Bit-by-bit, it means:

  • \{ Match a literal {.
  • (...) Match the content within normally, but capture whatever text it matched.
    • [A-Z] Match any character between A and Z.
  • \} Match a literal }.

We use preg_match_all to find all instances of this pattern. Group 0 is the entire match (including the braces), and group 1 contains only the data captured using the parentheses.
