preg_replace

Hi

I'm using the Jamie Rumbelow's "My_Model" class, and wanted to know exactly what this does:

Code:

$class = preg_replace('/(_m|_model)?$/', '', get_class($this));

strips _m or _model from the end of the class name if they are there

Hi

And if I do the same, but in the beginning?

Code:

$class = preg_replace('/(m_|model_)?$/', '', get_class($this));

This would be correct?

'/^(m_|model_)/'
