int bccomp ( string $left_operand , string $right_operand [, int $scale ] )

Compares the left_operand to the right_operand and returns the result as an integer.

left_operand: The left operand, as a string.
right_operand: The right operand, as a string.
scale: The optional scale parameter is used to set the number of digits after the decimal place which will be used in the comparison.

Returns 0 if the two operands are equal, 1 if the left_operand is larger than the right_operand , -1 otherwise.
