1.2.330. Declare strict_types Usage¶
Usage of strict_types. By default, PHP attempts to change the original type to match the type specified by the type-declaration. With an explicit strict_types declaration, PHP ensures that the incoming argument has the exact type.
strict_types were introduced in PHP 7.0.
<?php
// Setting strict_types;
declare(strict_types = 1);
function foo(int $i) {
echo $i;
}
// Always valid : displays 1
foo(1);
// with strict types, this emits an error
// without strict types, this displays 1
foo(1.7);
?>
