The SplBool class

(No version information available, might only be in SVN)

简介

The SplBool class is used to enforce strong typing of the bool type.

SplBool extends SplEnum {

/* Constants */

const boolean __default = false ;

const boolean false = false ;

const boolean true = true ;

/* 继承的方法 */

public array SplEnum::getConstList ([ bool $include_default = false ] )

}

Example #1 SplBool usage example


<?php
$true = new SplBool(true);
if ($true) {
    echo "TRUE\n";
}

$false = new SplBool;
if ($false) {
    echo "FALSE\n";
}
?>

以上例程会输出：

TRUE
