php 한글 메뉴얼 도움말 검색 사이트 Split string into array by regular expression [function.split]

설명

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

Splits a string into array by regular expression.

Warning

이 함수는 PHP 5.3.0부터 배제됩니다. 이 기능에 의존하지 않기를 권합니다.

인수

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() (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.

string

The input string.

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.

반환값

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() returns FALSE.

예제

Example #1 split() 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() 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 />\n";
?>

주의

Note:
PHP 5.3.0부터 regex 확장은 배제되었습니다. PCRE 확장이 같은 기능을 합니다. 이 함수를 호출하면 E_DEPRECATED 주의가 발생합니다. PCRE로 변환하는 데 필요한 도움은 차이점 목록을 참고하십시오.

Tip

split() is deprecated as of PHP 5.3.0. preg_split() is the suggested alternative to this function. 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.

Tip

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

참고

preg_split() - 정규 표현식에 따라 문자열을 나눔
spliti() - Split string into array by regular expression case insensitive
str_split() - 문자열을 배열로 변환
explode() - 문자열을 문자열로 나눕니다
implode() - 문자열로 배열 원소를 결합
chunk_split() - 문자열을 작은 조각으로 나눕니다
wordwrap() - Wraps a string to a given number of characters
