php 代码大全

1.子类访问父类静态方法

<?php
class A{

    static function loadById(){
        $class_name = get_called_class();
        $model = new $class_name('a');
        return $model;
    }
}
class B extends A{
    public $name; 
    public function __construct($str){
        $this->name = $str;
    }
}

echo "beginnn<Br>";
$obj = B::loadById();
echo $obj->name;
?>

 $list{id=1,name='jiang',age=10}

print_r(arrayChangeKey($list, 'id'));

arrayChangeKey()函数array[id]={name,age}

function arrayChangeKey($arr,$key)
    {/*{{{*/                                            
        $processedArr = array();
        if(is_array($arr) && !empty($arr)){
            foreach ($arr as $item)
            {
                $processedArr[$item[$key]] = $item;
            }
        }
        return $processedArr;   
    }
