First difference: An interesting example of a different behaviour between strtr and str_replace is in the comments section of the PHP Manual: <?php $arrFrom = array(“1″,”2″,”3″,”B”); $arrTo = array(“A”,”B”,”C”,”D”); $word = “ZBB2″; echo str_replace($arrFrom, $arrTo, $word); ?> I would expect as result: “ZDDB” However, this return: “ZDDD” (Because B = D according to our array) … Read more
Like this: str_replace(array(‘:’, ‘\\’, “https://stackoverflow.com/”, ‘*’), ‘ ‘, $string); Or, in modern PHP (anything from 5.4 onwards), the slighty less wordy: str_replace([‘:’, ‘\\’, “https://stackoverflow.com/”, ‘*’], ‘ ‘, $string);
You would use the replace method: text = text.replace(‘old’, ‘new’); The first argument is what you’re looking for, obviously. It can also accept regular expressions. Just remember that it does not change the original string. It only returns the new value.
std::string doesn’t contain such function but you could use stand-alone replace function from algorithm header. #include <algorithm> #include <string> void some_func() { std::string s = “example string”; std::replace( s.begin(), s.end(), ‘x’, ‘y’); // replace all ‘x’ to ‘y’ }
