使用ZF快速入门create model作为本主题的基础。
我想准确理解__construct和setOptions()方法在此上下文中应该做什么。 />
无论我敲了多少次,我都不知道这两种方法在做什么。
public function __construct(array $options = null)
{
//if it is an array of options the call setOptions and apply those options
//so what? What Options
if (is_array($options)) {
$this->setOptions($options);
}
}
public function setOptions(array $options)
{
//I can see this starts by getting all the class methods and return array()
$methods = get_class_methods($this);
//loop through the options and assign them to $method as setters?
foreach ($options as $key => $value) {
$method = 'set' . ucfirst($key);
if (in_array($method, $methods)) {
$this->$method($value);
}
}
return $this;
}
我真的迷失在setOptons()上,我无法弄清楚它想要完成什么。我理解这是抽象一些行为,我只是无法理解什么 据我所知,这就是'所以!'。我想理解它,因为它可能很重要。

如果您将$options
作为数组
{ ["name"] => "RockyFord" }
然后setOptions
方法将调用
setName("RockyFord");
如果此类中存在setName
方法。
foreach ($options as $key => $value) { // Loops through all options with Key,Value
$method = 'set' . ucfirst($key); // $method becomes 'setName' if key is 'name'
if (in_array($method, $methods)) { // Check if this method (setName) exists in this class
$this->$method($value); // Calls the method with the argument
}
}
