Possible Duplicate: Splitting a string in C++ In PHP, the explode() function will take a string and chop it up into an array separating each element by a specified delimiter. Is there an equivalent function in C++? Here's a simple example implementation: #include <string> #include <vector> #include <sstream> #include <utility> std::vector<std::string> explode(std::string const & s, char delim) { std::vector<std::string> result; std::istringstream iss(s); for (std::string token; std::getline(iss, token, delim); ) { result.push_back(std::move(token)); } return result; } Usage: auto v = explode(

Explode a paragraph into sentences in PHP

由 喜你入骨 提交于 2019-11-27 09:16:22
I have been using explode(".",$mystring) to split a paragraph into sentences. However this doen't cover sentences that have been concluded with different punctuation such as ! ? : ; Is there a way of using an array as a delimiter instead of a single character? Alternativly is there another neat way of splitting using various punctuation? I tried explode(("." || "?" || "!"),$mystring) hopefully but it didn't work... codaddict You can do: preg_split('/\.|\?|!/',$mystring); or (simpler): preg_split('/[.?!]/',$mystring); You can use preg_split() combined with a PCRE lookahead condition to split

PHP: Split string into array, like explode with no delimiter

由 瘦欲@ 提交于 2019-11-27 06:56:45
I have a string such as: "0123456789" and need to split EACH character into an array. I for the hell of it tried: explode('', '123545789'); But it gave me the obvious: Warning: No delimiter defined in explode) .. How would I come across this? I can't see any method off hand, especially just a function Erik $array = str_split("0123456789bcdfghjkmnpqrstvwxyz"); str_split takes an optional 2nd param, the chunk length (default 1), so you can do things like: $array = str_split("aabbccdd", 2); // $array[0] = aa // $array[1] = bb // $array[2] = cc etc ... You can also get at parts of your string by

php explode: split string into words by using space a delimiter

问题 $str = "This is a string"; $words = explode(" ", $str); Works fine, but spaces still go into array: $words === array ('This', 'is', 'a', '', '', '', 'string');//true I would prefer to have words only with no spaces and keep the information about the number of spaces separate. $words === array ('This', 'is', 'a', 'string');//true $spaces === array(1,1,4);//true Just added: (1, 1, 4) means one space after the first word, one space after the second word and 4 spaces after the third word.

Exploding by Array of Delimiters

问题 Is there any way to explode() using an array of delimiters? PHP Manual: array explode ( string $delimiter , string $string [, int $limit ] ) Instead of using string $delimiter is there any way to use array $delimiter without affecting performance too much? 回答1: Use preg_split() with an appropriate regex. 回答2: $str = 'Monsters are SUPER scary, bro!'; $del = array('a', 'b', 'c'); // In one fell swoop... $arr = explode( $del[0], str_replace($del, $del[0], $str) ); 回答3: function explode_by_array(

Parse SELECT clause of SQL queries into a PHP array

问题 This is more for analyzing a query in PHP BEFORE it's sent to the server. Very complicated why im doing this, so i'd rather not go into the reason for this. In PHP, i need to store the field selections into a php array. So take this query for example: SELECT user_id,username,DATE(join_datetime) as join_date, (SELECT COUNT(1) FROM foobar WHERE foonum IN (5,4,6) and user_id = users.user_id) as myfoo_count FROM users WHERE user_id = 123 So, in this case I need to store "user_id,username,DATE
