PHP 类初始化的时候,不能用变量参数么,怎么改呢?

Jun 23, 2016 pm 02:04 PM

在做 同志湾,然后遇到了问题。

我就想当函数用就够了,直接双引号没问题,换成变量就不响应。额

$entxt=$_GET["entxt"];
echo $entxt;
$x = new fanyi($entxt,1);
echo $x->go();
class fanyi
{

没理解

这个可以:

<?php$entxt=$_GET["entxt"];echo $entxt;$x = new fanyi($entxt;,1);echo $x->go();class fanyi{var $cilentID;var $clientSecret;var $authUrl;var $scopeUrl;var $grantType;var $inputstring;var $toLanguage;var $fromLanguage;function __construct($inputstring,$biao='0'){
Copy after login


这个不行
$entxt=$_GET["entxt"];
echo $entxt;
$x = new fanyi("hello baby",1);
echo $x->go();
class fanyi
{
var $cilentID;
var $clientSecret;
var $authUrl;
var $scopeUrl;
var $grantType;
var $inputstring;
var $toLanguage;
var $fromLanguage;
function __construct($inputstring,$biao='0')
{

直接双引号没问题,换成变量就不响应。

说反了,上面的不行,下面的可以

new fanyi($entxt ;,1);
多了个分号,造成语法错误不能解析,而你又屏蔽了错误提示,所以没能发现这个问题

同楼上,多了个分号

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

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,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

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.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
