title: Performance of try-catch in php
body: <p>What kind of performance implications are there to consider when using try-catch statements in php 5? </p>
  
  <p>I've read some old and seemingly conflicting information on this subject on the web before. A lot of the framework I currently have to work with was created on php 4 and lacks many of the niceties of php 5. So, I don't have much experience myself in using try-catchs with php.</p>
