SplType::__construct ([ mixed $initial_value [, bool $strict ]] )
}

Exemplos

Exemplo #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"
?>
