note 24671 added to function.wordwrap

Instead of using a space or a newline or <br /> as the line break separator, you may consider inserting "Soft Hyphens" within the middle of long words, allowing elegant word breaking that can use the effective browser layout that is dependant of the effective font that the browser will use. The "Soft Hyphen" (SHY) character is part of the STANDARD ISO-8859-1 character set: it won't be displayed (i.e. it will have width 0) if the two parts of a word can be displayed by the browser along on the same layout row. However it allows the browser to find a break in the middle of long words: in that case, it will display the first part of the word before the "Soft Hyphen", and a true Hyphen ("-") on the first layout row (if they both fit on that row), and the next part after the "Soft Hyphen" on the following layout row. Ideally, each word should contain at least one "Soft Hyphen" between each syllable of a word, unless this would place a "Soft Hyphen" with less than 3 characters from the beginning or end of the word. So "Soft Hyphens" must not be inserted within words with 1 to 5 characters. The Soft Hyphen is only appropriate within textual words using Latin, Greek, Cyrillic characters). For Semitic languages that use right to left scripts, the "Soft Hyphen" should be replaced by a "Soft Line Break" (also called "Zero Width Non Joiner" in Unicode). This "Soft Line Break" always has a null display width (i.e. it is never displayed), except that it allows inserting a line break. Some characters are already implicitly considered followed by a "Soft Line Break" in browsers: the explicit hyphen within composed words (like "week-end"), and all punctuations (with the exception of the dot, and opening punctuations like "({[" which are instead _preceded_ by an implicit "Soft Line Break"). Note also that some new browsers can insert themselves "Soft Hyphens" or "Soft Line Breaks" within long words, if the HTML page explicitly specifies the language, and the words are restricted to the natural characters of that language, using hyphenation rules and/or dictionnaries defined for that language. Currently, the HTML standard offers no way to specify a set of hyphenation rules along with the page (so that it would work in absence of a known dictionnary for that language), so soft hyphens or line breaks should be placed in the content. -- http://www.php.net/manual/en/function.wordwrap.php http://master.php.net/manage/user-notes.php?action=edit+24671 http://master.php.net/manage/user-notes.php?action=delete+24671 http://master.php.net/manage/user-notes.php?action=reject+24671
