spliti
(PHP 4 >= 4.0.1, PHP 5)
spliti — 用正则表达式不区分大小写将字符串分割到数组中
说明
array spliti
( string $pattern
, string $string
[, int $limit = -1
] )
用正则表达式将一个 string 分割成数组。
本函数和 split() 相同，只除了在匹配字母字符时忽略大小写的区别。
Warning
自 PHP 5.3.0
起，已经废弃此函数。强烈建议不要应用此函数 。
参数
pattern
大小写不敏感的正则表达式。
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 spliti() (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
输入的字符。
limit
如果设置了 limit，返回的数组最多会包含 limit 个元素，最后一个元素包含了剩下的全部 string。
返回值
Returns an array of strings, each of which is a substring of
string formed by splitting it on boundaries formed
by the case insensitive 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,
spliti() returns FALSE.
范例
本例用 'a' 做分隔符来分割一个字符串：
Example #1 spliti() 例子
<?php
$string = "aBBBaCCCADDDaEEEaGGGA";
$chunks = spliti ("a", $string, 5);
print_r($chunks);
?>
以上例程会输出：
Array ( [0] => [1] => BBB [2] => CCC [3] => DDD [4] => EEEaGGGA )
注释
Note:
在 PHP 5.3.0
中，已放弃使用 regex 扩展而建议使用 PCRE 扩展。调用此函数将会发出
E_DEPRECATED 通知。参见“差异列表”可帮助你转为使用 PCRE。
