Einführung

The SplString class is used to enforce strong typing of the string type.

Klassenbeschreibung

/* Constants */
const integer __default = 0 ;
/* Geerbte Methoden */
SplType::__construct ([ mixed $initial_value [, bool $strict ]] )
}

Vordefinierte Konstanten

Beispiele

Beispiel #1 SplString usage example

<?php
$string 
= new SplString("Testing");

try {
    
$string = array();
} catch (
UnexpectedValueException $uve) {
    echo 
$uve->getMessage() . PHP_EOL;
}

var_dump($string);
echo 
$string// Outputs "Testing"
?>

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

Value not a string
object(SplString)#1 (1) {
  ["__default"]=>
  string(7) "Testing"
}
Testing
