直接上代码
<?php
class example{
public static $pa;
public $pb;
public function __construct(){
$this->pb = ++self::$pa;
}
}
$a = new example;
$b = new example;
echo $a->pb;
echo ‘<hr/>‘;
echo $b->pb;
?>
本来想结果应该是
1 ----------------------------------------------------- 1
可是我错了，正确的结果是
1 ---------------------------------------------------------------------------------- 2
基础没学好，赶快补补
