PHP RegEx和部分字符串

Question

I have strings, for example:

bool dxDrawImage float posX, float posY, float width, float height, mixed image , float rotation = 0, float rotationCenterOffsetX = 0, float rotationCenterOffsetY = 0, int color = white, bool postGUI = false
bool dxUpdateScreenSource element screenSource, bool resampleNow =false

I need get parts from it, for example:

bool dxDrawImage
float posX
float posY
...

I wrote:

preg_match_all("/(bool|float|int)[a-zA-Z0-9\s=]+/", $txt, $ar);

print_r($ar):

Array ( [0] => Array ( [0] => bool dxDrawImage float posX [1] => float posY [2] => float width [3] => float height [4] => float rotation = 0 [5] => float rotationCenterOffsetX = 0 [6] => float rotationCenterOffsetY = 0 [7] => int color = white [8] => bool postGUI = false ) [1] => Array ( [0] => bool [1] => float [2] => float [3] => float [4] => float [5] => float [6] => float [7] => int [8] => bool ) )

Why this regexp capture bool dxDrawImage float posX instead

bool dxDrawImage
float posX

How to fix this?

preg_match_all("/(\b(?:bool|float|int|element)\s+.*?)(?=\b(?:bool|float|int|element|[,;
]|$))/", $txt, $ar); 
print_r($ar[1]);
