Otherwise every time that substr is called on the object a __toString() is called, which affects performance quite a bit if you do it often. | |

when calling echo on an object PHP tries to convert it to string so it calls the same __toString method.

Regarding the memory usage, simply assigning $this->helper()->... to a variable allocates ~500MB of memory on certain products. I have a post here: magento.stackexchange.com/questions/8113/…. But I do need to run some more tests to cases.

Ah, does __toStrign() work the same for string-casting inside PHP and when echoing in HTML?
