[OWASP_PHPSEC] Concatenating random numbers

Hello All,

I have this doubt that if I concatenate two smaller random numbers to
generate a larger random number, then will that affect security ?

Suppose I have two 32 length random numbers and I concatenated them and
created a 64 length random number.
str1 (length 64) = generated by concatenating two 32 length strings
str2 (length 64) = generated directly from the function

Now which of those two strings are more secure ?
