Coming from an application development environment (Java, C#, C++);
Is there no limit specified by a PHP (Zend) coding standard which sets a guideline to how long the body of a method can be? When programming an application a method should only have one task, delegate everything else. And the body of a method should never be so long that you can't view it in one page (about 40-45 lines, the shorter the better).

Are there some similar guidelines in PHP. I've never seen a guideline concerning PHP for how long methods should be.
