split

SPLIT(3)								 1								  SPLIT(3)

split - Split string into array by regular expression

SYNOPSIS

       array split (string  $pattern, string  $string, [int  $limit = -1])

DESCRIPTION

	Splits a $string into array by regular expression.

       Warning

	      This function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged.

PARAMETERS

	      o $pattern
		-  Case  sensitive  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(3) (or any other regex function, for that matter) is doing some-
		thing 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.

	      o $string
		- The input string.

	      o $limit
		- If $limit is set, the returned array will contain a maximum of $limit elements with the last element containing the  whole  rest
		of $string.

RETURN VALUES

	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 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. If an error occurs, split(3) returns FALSE.

EXAMPLES

       Example #1

	      split(3) example

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

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

       Example #2

	      split(3) example

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

	      <?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 />
";
	      ?>

NOTES

       Note

	      As  of PHP 5.3.0, the regex extension is deprecated in favor of the PCRE extension. Calling this function will issue an E_DEPRECATED
	      notice. See the list of differences for help on converting to PCRE.

       Tip

	      split(3) is deprecated as of PHP 5.3.0. preg_split(3) is the suggested alternative to this function. If you don't require the  power
	      of regular expressions, it is faster to use explode(3), which doesn't incur the overhead of the regular expression engine.

       Tip

	       For  users  looking  for  a  way to emulate Perl's @chars = split('', $str) behaviour, please see the examples for preg_split(3) or
	      str_split(3).
