With /e, the replacement string is a PHP expression.So when you use a backreference in the replacement expression, you need to put the backreference inside quotes, or otherwise it would be interpreted as PHP code.$buffer = str_replace('/// ', '///', $buffer); $buffer = str_replace(',//', ', //', $buffer); $buffer = str_replace(' //', $buffer); $buffer = str_replace('*//*', '*/ /*', $buffer); $buffer = str_replace('/**/', '/* */', $buffer); $buffer = str_replace('*///', '*/ //', $buffer); $buffer = preg_replace("/\/\/.*\n\/\/.*\n/", "", $buffer); $buffer = preg_replace("/\s\/\/\".*/", "", $buffer); $buffer = preg_replace("/\/\/\n/", "\n", $buffer); $buffer = preg_replace("/\/\/\s.*.\n/", "\n \n", $buffer); $buffer = preg_replace('/\/\/w[^w].*/', '', $buffer); $buffer = preg_replace('/\/\/s[^s].*/', '', $buffer); $buffer = preg_replace('/\/\/\*\*\*.*/', '', $buffer); $buffer = preg_replace('/\/\/\*\s\*\s\*.*/', '', $buffer); $buffer = preg_replace('/[^\*]\/\/[*].*/', '', $buffer); $buffer = preg_replace('/([;])\/\/.*/', '

the only problem being in the name attribute I follow common programming guidelines and have names like the following: event Date, event Time, user Email, etc.

Because double-quotes are a really bad idea anyway (due to the variable expansion), I would suggest that preg_replace's auto-escaping is modified to suit the placement of backreferences inside single-quotes (which seemed to be the intention from the start, but was incorrectly applied).

People using functions like scandir with user input and protecting against "../" by using preg_replace make sure you run ir recursivly untill preg_match no-long finds it, because if you don't the following can happen.

If your buffer is larger than this, look to increase these two values.
