PHP Manual: Implements an interface at runtime

bool uopz_implement(string $class, string $interface)

Makes class implement interface

Returns true on success or false on failure.

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

Example #1 uopz_implement example

<?php
interface myInterface {}

class myClass {}

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

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

The above example will output:

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