/**
* Checks whether the string "str" with length "length" is numeric. The value
* of allow_errors determines whether it's required to be entirely numeric, or
* just its prefix. Leading whitespace is allowed.
*
* The function returns 0 if the string did not contain a valid number; IS_LONG
* if it contained a number that fits within the range of a long; or IS_DOUBLE
* if the number was out of long range or contained a decimal point/exponent.
* The number's value is returned into the respective pointer, *lval or *dval,
* if that pointer is not NULL.
*
* This variant also gives information if a string that represents an integer
* could not be represented as such due to overflow. It writes 1 to oflow_info
* if the integer is larger than ZEND_LONG_MAX and -1 if it's smaller than ZEND_LONG_MIN.
