note 87977 added to function.strtok

This looks very simple, but it took me a long time to figure out so I thought I'd share it incase someone else was wanting the same thing: this should work similar to substr() but with tokens instead! <?php /* subtok(string,chr,pos,len) * * chr = chr used to seperate tokens * pos = starting postion * len = length, if negative count back from right * * subtok('a.b.c.d.e','.',0) = 'a.b.c.d.e' * subtok('a.b.c.d.e','.',0,2) = 'a.b' * subtok('a.b.c.d.e','.',2,1) = 'c' * subtok('a.b.c.d.e','.',2,-1) = 'c.d' * subtok('a.b.c.d.e','.',-4) = 'b.c.d.e' * subtok('a.b.c.d.e','.',-4,2) = 'b.c' * subtok('a.b.c.d.e','.',-4,-1) = 'b.c.d' */ function subtok($string,$chr,$pos,$len = NULL) { return implode($chr,array_slice(explode($chr,$string),$pos,$len)); } ?> explode breaks the tokens up into an array, array slice alows you to pick then tokens you want, and then implode converts it back to a string although its far from a clone, this was inspired by mIRC's gettok() function ---- Server IP: 64.71.164.2 Probable Submitter: 76.193.203.6 ---- Manual Page -- http://www.php.net/manual/en/function.strtok.php Edit -- https://master.php.net/note/edit/87977 Del: integrated -- https://master.php.net/note/delete/87977/integrated Del: useless -- https://master.php.net/note/delete/87977/useless Del: bad code -- https://master.php.net/note/delete/87977/bad+code Del: spam -- https://master.php.net/note/delete/87977/spam Del: non-english -- https://master.php.net/note/delete/87977/non-english Del: in docs -- https://master.php.net/note/delete/87977/in+docs Del: other reasons-- https://master.php.net/note/delete/87977 Reject -- https://master.php.net/note/reject/87977 Search -- https://master.php.net/manage/user-notes.php
