Syntax error with constant arrays

[mundschenk-at]

When a plugin includes constant arrays (a feature since PHP 5.6), the parser throws an error and appears to continue the import, but really skips the file.

Example:

Parse Error: Syntax error, unexpected '[' on line 544Starting import. This will take some time…

The code in question (starting with line 544):

			if ( ! empty( self::COLUMN_FORMAT_STRINGS[ $key ] ) ) {
				$format_strings[] = self::COLUMN_FORMAT_STRINGS[ $key ];
			}

Neither the containing class nor any hooks etc. appear in the generated code reference.
