The PHP 8.6 "Deprecations for PHP 8.6" RFC proposes deprecating the legacy type-check aliases is_double(), is_integer(), and is_long() in favor of their canonical counterparts, with removal targeted for PHP 9.

Replace the two occurrences in core:

  • is_double() becomes is_float()
  • is_long() becomes is_int()

Behavior is unchanged; the canonical functions are exact equivalents.

The remaining is_integer() usage lives in getID3 and has been fixed upstream; it will be picked up with the next library release.

Follow-up to [62175].

…ad of PHP 8.6.

The PHP 8.6 "Deprecations for PHP 8.6" RFC proposes deprecating the legacy type-check aliases `is_double()`, `is_integer()`, and `is_long()` in favor of their canonical counterparts, with removal targeted for PHP 9.

Replace the two occurrences in bundled libraries that are maintained in core: `is_double()` becomes `is_float()` in the IXR `IXR_Value::calculateType()` method, and `is_long()` becomes `is_int()` in the PEMFTP `ftp_base::SetServer()` method. Behavior is unchanged; the canonical functions are exact equivalents.

The remaining `is_integer()` usage lives in getID3 and has been fixed upstream; it will be picked up with the next library release.
