fopen uses stat cache in PHP5. It could cause problems if you open files in append mode, as the file
pointer will point on last known end of file, and does not check if the file is bigger.
Example :
// first call creates the file an set position to zero
$f = fopen("filename.txt", "a");
fputs($f, "Hello World\n");
fclose($f);
// PHP4 : second call opens the file and points on end
// PHP5 : second call opens the file and points on zero !
// you should do a clearstatcache(); here
$f = fopen("filename.txt", "a");
fputs($f, "Second Hello World over\n");
fclose($f);
// result in PHP5 : the file only contains "Hello World over"
