I added a line to that function word_wrap(), found at " http://morannon.the-infinite.org/archive/php/word_wrap
", because i need to convert \n 's to < br >'s to insert in my table...
this function added one '\n' when encountering one other...
it gives :
/* word_wrap($string, $cols, $prefix)
*
* Takes $string, and wraps it on a per-word boundary (does not clip
* words UNLESS the word is more than $cols long), no more than $cols per
* line. Allows for optional prefix string for each line. (Was written to
* easily format replies to e-mails, prefixing each line with "> ".
*
* Copyright 1999 Dominic J. Eidson, use as you wish, but give credit
* where credit due.
