Hi All, I need some help in searching string in a file.
My requirement is to search the string,append something to the string . Write the string back to the file without changing other parts of the file. e.g Suppose I have the following string in a file Set-Cookie: T_COOKIE=127.0.0.1-saswat-9; path=/ The fixed string is "Set-Cookie: T_COOKIE="and rest of the string is variable. I would like to change the string "127.0.0.1-saswat-9" to say "127.0.0.1-saswat-9-1234" My constraint is : I don't want to read the whole file into a buffer and work on that buffer as the file can be very large , sometimes more than 10 mb. My advantage is : I know that I will get the search string in first 200 bytes of the file , so I just need to read 200 bytes,play with that and write it back (overwriting the first 200 bytes with new 200 some bytes) .. Would appreciate any help or pointers. Thanks, -Saswat -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
