不过php提供了pack和unpack函数,用来进行二进制数据(binary data)和php内部数据的互转: 复制代码代码如下: string pack ( string $format [, mixed $args [, mixed $...]] ) //Pack given arguments into binary string according to format. array unpack ( string $format, string $data ) //Unpacks fr...
序列化对象销毁,触发__destruct,判断op值如果强等于“2”则把op重置为“1”,注意这里的“2”是字符串,然后把content置空,执行process函数,进入process函数后先判断op,op等于“1”进入write函数,op等于“2”进入read函数(write函数实现一个文件写入的功能,read函数实现一个文件读取的功能)...

public function__unserialize(array$data):void; ?> 新的序列化机制取代了Serializable接口,并且将会在未来弃用。 不带参数的数组合并函数 现在可以不带任何参数调用array_merge()和array_merge_recursive(),此时会返回空数组。这跟展开运算符结合非常有用,比如array_merge(...$arrays)。
public SoapClient::SoapClient ( mixed $wsdl [, array $options ] ) 第一个参数是用来指明是否是wsdl模式,如果为null,那就是非wsdl模式,反序列化的时候会对第二个参数指明的url进行soap请求。 用Soap进行SSRF也有两个需要注意的点: Soap不是默认开启的,需要手动开启 需要触发__call方法才能进行SSRF SOAP =...
