In strict mode, only the variables exactly matching the declaration types are accepted. Strict type-checking mode can be enabled:

  • Per file, if the declare(strict_types=1) directive is specified. The directive must be the first statement in a file, block mode is explicitly disallowed.

  • For all files, if the Enable for all files inspection option is enabled.

See Strict typing (php.net) for details.
