![]() ![]() The first ? prevents capturing an additional group. In your case, it would probably be best to split on non-word characters \W+, then manually filter the results for length. So matches0 in the firat example is the equivilant of tiele in the second. If the Cut is set to, TRUE the string is always wrapped at or before the specified Width. Matches0 contains all patterns matched by /w+/. The line breaks with optional Break parameter. A Width is a number of characters at which the string will be wrapped. While explode will split on constant values, pregsplit will split based on a regular expression. In above syntax wordwrap function has four parameters. It can read a given file and split it into multiple files, each with a chunk delimited by. (?(?!$delimiter).)* means: match only characters that do no start the word $delimiter. Simply put, you need to use pregsplit instead of explode. This class can split files into chunks divided by pattern strings. The regular expression has to be adapted here, using a negative look-around (as explained in this answer): $string = "one and two and three and four and five" PREG_SPLIT_NO_EMPTY is there because, I'm not sure why, the split gives an empty string at the end. split array split(string pattern, string subject, int limit) pattern Regex pattern to split by subject Input string to split. In this case we need to find the product and add the change to the number after the + sign. This method uses pregreplacecallback which finds patterns and returns the string according to what you want done with it. ![]() The regular expression matches the last delimiter with the last item, but captures only the item so that it's kept in the results thanks to PREG_SPLIT_DELIM_CAPTURE. If you first explode then you need to loop or regex each item of the array. 1, PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_NO_EMPTY) It is the opposite of PHP’s implode() function that converts an array to a string. $array = preg_split("/".$delimiter."(+)$/", $string, PHP’s built-in explode function lets you take a string and convert it to an array. The regexp will look like this: /,(+)$/ You can also use preg_split: Single-character delimiter $string = "one,two,three,four,five" Explanation: The trick is to match parenthesis before the, Pattern delimiter ' ' All charaters but not a single quote + one or more times ' or \ ( )+\) the same with parenthesis or ,+ Any characters except commas one or more times. ![]()
