title: PHP landmines in general
body: <p>What surprises have other people found with writing PHP web applications?  There's the well known and to be fixed issue with compile time class inheritance but I know of a couple others and wanted to try and build a list of the top gotcha's of the language.</p>
  
  <p>Note: </p>
  
  <p>I've held several positions as a Sr. PHP5 developer so PHP work pays my bills, this question is not meant to bust on PHP as a language as every single language I've worked with has some well known or not so well known surprises.</p>
