I need to calculate in PHP, Normal Distribution that matches results using Excel Normal Distribution Function NORMDIST(x, mean, standard_dev, accumulative)

I tried few methods but couldn't get correct results which is 0.513 according to the Excel formula of NORMDIST(x, mean, standard_dev, accumulative) with following input values:

Z=65, mean=64.43, standard_dev=18.76, accumulative=1

Result should be 0.513

Any help please ?
