The probleme is here if : (strpos($buffer, '<?') === true){
strpos returns the position of the first occurence of your searched
string or FALSE if it doesn't find it.
The operator === is a STRICT comparison, that means that it'll be true
if the operands are EXACTLY the same.
As your strpos finds a '<?', it returns its position in your file,
(ie: 45), and 45 is not EXACTLY true.
You have to change
strpos($buffer, '<?') === true){
for
strpos($buffer, '<?') !== false){
