关于array_diff函数的问题
我用array_diff对比读取到的txt文件标题是否和我设定的一样,其中最后一个字段始终判定为不一样,表面看最后一个字段多了一个空格,我加了一个空格,也判定不一样,请问我用什么方法看txt文件最后一个字段的内容是什么??
回复讨论(解决方案)
把??txt??base64,再看看是否相同。
可以把你的代码粘贴出来吗???
需要看到你的代码和测试数据
private function CheckFileType($array){ $type=""; foreach($this->filetypearray as $name=>$value){ $ar=array_diff($array,$value); if(empty($ar)){ $type=$name; } } return $type; }private $filetypearray=array( 'downloadfile'=>array('order-id','order-item-id','purchase-date','payments-date','buyer-email', 'buyer-name','buyer-phone-number','sku','product-name','quantity-purchased','currency','item-price', 'item-tax','shipping-price','shipping-tax','ship-service-level','recipient-name','ship-address-1', 'ship-address-2','ship-address-3','ship-city','ship-state','ship-postal-code','ship-country', 'ship-phone-number','delivery-start-date','delivery-end-date','delivery-time-zone',"delivery-Instructions ") ); $order['28']='('.base64_encode($more[28]).')'; $order['29']='('.base64_encode($this->filetypearray['downloadfile'][28]).')';[28] => (ZGVsaXZlcnktSW5zdHJ1Y3Rpb25zDQ==)[29] => (ZGVsaXZlcnktSW5zdHJ1Y3Rpb25zIA==)
两个字段的base64结果,最后部分不一样
那个DQ==是什么??我不加空格编码就是ZGVsaXZlcnktSW5zdHJ1Y3Rpb25z
base64 编码的:
DQ== 是回车符 0x0d (chr(13))
IA== 是空格符 0x20 (chr(32))
一般情况下首尾的空白字符是可忽略的,所以宜 trim 一下
$ar = array_diff(array_map('trim', $array), array_map('trim', $value));

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
