(PECL uopz 1, PECL uopz 2, PECL uopz 5, PECL uopz 6, PECL uopz 7 < 7.1.0)

uopz_implement — Implements an interface at runtime

uopz_implement(string $class, string $interface): bool

Makes class implement interface

成功时返回 true，或者在失败时返回 false。

As of PHP 7.4.0, uopz_implements() throws a RuntimeException, if OPcache is enabled, and the class entry of class is immutable.

示例 #1 uopz_implement() example

<?php
interface myInterface {}

class myClass {}

uopz_implement(myClass::class, myInterface::class);

var_dump(class_implements(myClass::class));
?>

以上示例会输出：

array(1) {
  ["myInterface"]=>
  string(11) "myInterface"
}
