A common mistake is given in the previous example. That is, if the string you're searching for occurs over a boundary (in this case, of 4k). For example, if the word "hello" were found starting at the 8th character and I read 10 characters, "hello" would not be found. If I read the next 10 characters, "hello" would again not be found (although "llo" would be). One solution is to always increment your buffer by BUFFER_SIZE - (SEARCH_STR_LEN-1). That will make sure your search string shows up. $i = 0; $search = "hello"; (loop while not eof ...) $i += 4096 - (strlen($search) - 1);
