使用ZF快速启动创建模型作为本主题的基础
我想确切地了解__construct和setOptions()方法在这种情况下应该做什么
不管我敲了多少次,我都不明白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 $this;
}
我真的迷上了setOptons(),我不知道它想要实现什么。我知道这是在抽象一些行为,我只是不太明白是什么
据我所知,这只是太多了。我想理解它,因为它可能会被证明是重要的。
如果将$options
作为数组传递
{ ["name"] => "RockyFord" }
则CCD_ 2方法将调用
setName("RockyFord");
如果该类中存在CCD_ 3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
}
}
