spliti — Split string into array by regular expression case insensitive
Описание
Splits a string into array by regular expression.
This function is identical to split() except that this ignores case distinction when matching alphabetic characters.
Список параметров
- 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 .
Возвращаемые значения
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.
Примеры
This example splits a string using 'a' as the separator :
Пример #1 spliti() example
<?php
$string = "aBBBaCCCADDDaEEEaGGGA";
$chunks = spliti ("a", $string, 5);
print_r($chunks);
?>
Результат выполнения данного примера:
Array ( [0] => [1] => BBB [2] => CCC [3] => DDD [4] => EEEaGGGA )
Коментарии
To split $cartes which contains data and tabulations:
Doesnt work :
$tab_cartes = split("\\t",$cartes );
But \t = char(9), so, works well:
$tab_cartes = split(Chr(9),$cartes);
Idem for :
\n = char(10)
\r = char(13)

When using special characters such as the tab placeholder "\t" in the split function, be careful not to escape the slash by adding a slah in front of it. To signify a tab, new line or carriage return use only one slash in front of the character. For example:
$cartes= "one\ttwo\tthree";
$tab_cartes = split("\t",$cartes );
$items = count($tab_cartes);
for ($x = 0; $x < $items; $x++)
{ echo $tab_cartes[$x] . "\n"; }
This example shows the use of spliti.
Here it splits the path of the server as it can be used further.
<?php
require_once 'Beispiel.php';
$seq = new Sequence();
$path = $_SERVER["PATH_INFO"];
echo "PATH: ".$path."<br/>";
echo "Request mode: ".$_SERVER["REQUEST_METHOD"]."<br/>";
$daten = spliti ("/", $path);
echo "get-daten[1] ".$daten[1]."<br/>";
if($_SERVER["REQUEST_METHOD"]== "POST"){
echo "POST".$daten[1];
$seq->setzeSequence($daten[1], $_POST["xml"]);
}
elseif($_SERVER["REQUEST_METHOD"] == "DELETE"){
echo "DELETE".$daten[1];
$seq->loescheSequence($daten[1]);
}
elseif($_SERVER["REQUEST_METHOD"] == "GET"){
$antwort = $seq->holeSequence($daten[1]);
echo "antwort[0]: ".$antwort[0]."<br/>";
foreach($antwort as $mes){
echo "mes ".$mes."<br/>";
}
}
?>
