# variant_cmp

(PHP 5)

variant_cmp — Compares two variants

### Описание

int variant_cmp ( mixed `$left` , mixed `$right` [, int `$lcid` [, int `$flags` ]] )

Compares `left` with `right` .

This function will only compare scalar values, not arrays or variant records.

### Список параметров

`left`

  The left operand.

`right`

  The right operand.

`lcid`

  A valid Locale Identifier to use when comparing strings (this affects string collation).

`flags`

  `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

> Замечание: 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.

### Возвращаемые значения

Returns one of the following:

Variant Comparision Results
value | meaning
--- | ---
`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`
