- @Devon This is true, NEVER eval a user input, but the accepted answer in that question has a split solution, that he can use.Peon– Peon2018-08-06 17:14:55 +00:00Commented Aug 6, 2018 at 17:14
- @Peon, that split solution only looks to work with a very basic math expression, not what the OP has provided, but there are other answers there that attempt to sanitize.Devon Bessemer– Devon Bessemer2018-08-06 17:17:26 +00:00Commented Aug 6, 2018 at 17:17

Maybe your question is a possible duplicate from calculate-math-expression-from-a-string-using-eval
However
if you need to store this in a variable you can do
$string='((((((4,50*0,86)*52500*1,0016)+3800)/52500)*2,2046)*1,05)'; $response=eval('return '.str_replace(',','.',$string.';')); print($response); the output is:
