PHP validated fails because PHP is looking for files which are central included.
You can include files central with the -d argument. You must exclude that file from the validation.
<project>
......
			<plugin>
				<groupId>org.phpmaven</groupId>
				<artifactId>maven-php-plugin</artifactId>
				<extensions>true</extensions>
				<configuration>
					<compileArgs>
						-d auto_prepend_file=core.php
					</compileArgs>
				    <excludeFromValidation>
				        <file>core.php</file>
				   </excludeFromValidation>
				     
			   </configuration>
			</plugin>
......			
</project>
