php - Why file_put_contents() not always rewrites a file? -


i wonder, why php file_put_contents() function works in weird way.

i used in loop write logs file , fine (new lines appended if no flag specified). when started script again, re-created file.

from php doc:

if filename not exist, file created. otherwise, existing file overwritten, unless file_append flag set.

ok, question is: why (when used in 1 loop) doesn't overwrite file (without file_append flag of course)? bug or feature? :)

edit: example context of use when happened:

$logfile = dirname ( __file__ ) . '/example.log'; foreach($something1 $sth1) {     $logdata .= "something\n";     foreach($something2 $sth2) {         if($something_else) {             $logdata .= "line: \t" . $sth2 . "\n";             file_put_contents($logfile, $logdata);         }     } }

as has been mentioned in this link under flags content(which should have read) states if file filename exists, append data file instead of overwriting it(when flag set). when flag file_append set appends , when not rewrites. hope helped you.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
