variant_cmp — Compares two variants
Compares left with right.
This function will only compare scalar values, not arrays or variant records.
The left operand.
The right operand.
A valid Locale Identifier to use when comparing strings (this affects string collation).
flags can be one or more of the following values OR'd together, and affects string comparisons:
Variant Comparision Flags value meaning NORM_IGNORECASE Compare case insensitively NORM_IGNORENONSPACE Ignore nonspacing characters NORM_IGNORESYMBOLS Ignore symbols NORM_IGNOREWIDTH Ignore string width NORM_IGNOREKANATYPE Ignore Kana type NORM_IGNOREKASHIDA Ignore Arabic kashida characters
As with all the variant arithmetic functions, the parameters for this function can be either a PHP native type (integer, string, floating point, boolean or NULL), or an instance of a COM, VARIANT or DOTNET class. PHP native types will be converted to variants using the same rules as found in the constructor for the VARIANT class. COM and DOTNET objects will have the value of their default property taken and used as the variant value.
The variant arithmetic functions are wrappers around the similarly named functions in the COM library; for more information on these functions, consult the MSDN library. The PHP functions are named slightly differently; for example variant_add() in PHP corresponds to VarAdd() in the MSDN documentation.
Returns one of the following:
|VARCMP_LT||left is less than right|
|VARCMP_EQ||left is equal to right|
|VARCMP_GT||left is greater than right|
|VARCMP_NULL||Either left, right or both are NULL|
