note 74639 added to language.operators.increment

A more detailed explanation of the string incremant is: First of all it is checked wether the string is a standart representaion of a number wich is true if it equals the regex /^ *[+-]?[0-9]*(\.[0-9]|[0-9]\.)[0-9]*([eE]?[+-]?[0-9]+)?$/ but not the regex /\+\./ (no idea why). if it does, the type is changed to integer (if it equals /^ *[+-]?[0-9]+$/) or to float and then incremented by one. An empty string becomes the string "1". Otherwise if the last character is one of [0-8], [a-y] or [A-Y] it is incremented. If it is Z it puts it back to A, is z to a, if 9 to 0 and trys to do the same with the previouse character. If a character is reatched that is not in [0-9a-zA-Z], nothing is done anymore (that's why " Z" will increment to " A"). If the begining is reached a new caracter is prepended. "1" "a" or "A" depending on wether the first character was "9", "z" or "Z". If the last character was not [0-9a-zA-Z] the string isn't chaged. hope this helps someone ---- Server IP: 69.147.83.197 Probable Submitter: 84.158.116.149 ---- Manual Page -- http://www.php.net/manual/en/language.operators.increment.php Edit -- https://master.php.net/note/edit/74639 Del: integrated -- https://master.php.net/note/delete/74639/integrated Del: useless -- https://master.php.net/note/delete/74639/useless Del: bad code -- https://master.php.net/note/delete/74639/bad+code Del: spam -- https://master.php.net/note/delete/74639/spam Del: non-english -- https://master.php.net/note/delete/74639/non-english Del: in docs -- https://master.php.net/note/delete/74639/in+docs Del: other reasons-- https://master.php.net/note/delete/74639 Reject -- https://master.php.net/note/reject/74639 Search -- https://master.php.net/manage/user-notes.php
