c++ - What are differences between std::string and std::vector<char>? -


so main differences , of them used in cases?

  • vector<char> gives guarantee &v[0]+n == &v[n] whereas string doesn't (practically, case, there no guarantee)... afaik c++0x gives guarantee already
  • there no implicit conversion const char* vector<char>
  • string not stl container. example, has no pop_back() or back() functions
  • and last, not least, different member functions! string gives functions suitable strings, returnig null-terminated string c_str()

bottom line: use string when need operate strings. use vector<char> when need ... well, vector of individual chars...

another use of vector<char> way avoid vector<bool> specialization.

php cli reading files and how to fix it? -

while using php cli in ubuntu got apache web server cant read file can while using in browser. , error shows nothing , next used code testing purposes : <? $handle = fopen("testfile.txt", "r"); if ($handle) { while (($buffer = fgets($handle, 4096)) !== false) { echo $buffer; } if (!feof($handle)) { echo "error: unexpected fgets() fail\n"; } if(!is_readable($handle) { die("not readable"); } fclose($handle); } ?> how fix ? edit : after removing '@' before fopen got following error fopen(testfile.txt): failed open stream: no such file or directory in /var/www/log/ka.php on line 2 when run script through cli, uses shell's working directory, in opposition file's directory (which apache hands current directory). important you, since fopen call depends on relative path; , relative paths resolved relatively working directory, not script. to have script behave apache, eit...
