spliti
(PHP 4 >= 4.0.1, PHP 5)
spliti — Split string into array by regular expression case insensitive
說明
array spliti
( string $pattern
, string $string
[, int $limit
= -1
] )
This function is identical to split() except that this
ignores case distinction when matching alphabetic characters.
Warning自 PHP 5.3.0
起,已經廢棄此函式。強烈建議不要使用此函式。
參數
-
pattern
-
Case insensitive 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 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
-
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
.
回傳值
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
.
範例
This example splits a string using 'a' as the separator :
Example #1 spliti() example
<?php
$string = "aBBBaCCCADDDaEEEaGGGA";
$chunks = spliti ("a", $string, 5);
print_r($chunks);
?>
Array
(
[0] =>
[1] => BBB
[2] => CCC
[3] => DDD
[4] => EEEaGGGA
)
註釋
Note:
在 PHP 5.3.0
中,已放棄使用 regex 擴充功能而建議使用 PCRE 擴充功能。呼叫此函式會發出
E_DEPRECATED
通知。參見“差異列表”可幫助轉換使用 PCRE。
Tip
spliti() is deprecated as of PHP 5.3.0. preg_split()
with the i (PCRE_CASELESS
) modifier is the suggested alternative.
