                                     split

   (PHP 3, PHP 4 )
   split -- split string into array by regular expression

Description

   array split ( string pattern, string string [, int limit])

     Tip: preg_split(), which uses a Perl-compatible regular expression
     syntax, is often a faster alternative to split(). If you don't
     require the power of regular expressions, it is faster to use
     explode(), which doesn't incur the overhead of the regular
     expression engine.

   Returns an array of strings, each of which is a substring of string
   formed by splitting it on boundaries formed by the case-sensitive
   regular expression pattern. If limit is set, the returned array will
   contain a maximum of limit elements with the last element containing
   the whole rest of string. If an error occurs, split() returns FALSE.

   To split off the first four fields from a line from /etc/passwd:

   Example 1. split() example
   <?php
   list($user, $pass, $uid, $gid, $extra) =
       split(":", $passwd_line, 5);
   ?>

   If there are n occurrences of pattern, the returned array will contain
   n+1 items. For example, if there is no occurrence of pattern, an array
   with only one element will be returned. Of course, this is also true
   if string is empty.

   To parse a date which may be delimited with slashes, dots, or hyphens:

   Example 2. split() example
   <?php
   // Delimiters may be slash, dot, or hyphen
   $date = "04/30/1973";
   list($month, $day, $year) = split('[/.-]', $date);
   echo "Month: $month; Day: $day; Year: $year<br />\n";
   ?>

   For users looking for a way to emulate Perl's @chars = split('', $str)
   behaviour, please see the examples for preg_split().

   Please note that pattern is a regular expression. If you want to split
   on any of the characters which are considered special by regular
   expressions, you'll need to escape them first. If you think split()
   (or any other regex function, for that matter) is doing something
   weird, please read the file regex.7, included in the regex/
   subdirectory of the PHP distribution. It's in manpage format, so
   you'll want to do something along the lines of man
   /usr/local/src/regex/regex.7 in order to read it.
