How can I add or subtract amount based on decimal points in PHP / CI? I.e. if the amount is 5.11 it should return 5 and if amount is 5.66 it should return 6. Subtract +1 if decimal is greater then 50 and subtract if lesser or equal to 50

What I have tried:

We can use decimal detection and then ceil and floor function accordingly but seeking if there is library or function avaliable

What you've described is just normal rounding (unless I am missing something)

PHP accomplishes this with the round function.

round(5.11);
round(5.6);

Round function documentation

PHP: round - Manual[^]
