HomeBackend DevelopmentPHP Tutorial 怎么将变量插入字符串

如何将变量插入字符串
举个例子来说把,

$s   =   $_GET[ "word "];
echo   "your   word   is   $s ";

上面代码运行是没有问题的,但是如果换成这样就不行了:

echo   'your   word   is   $s ';

那么就不要用 ' '了,但是实际情况是,有时候往往必须用 ' ',   比如我要输出   link   ,由于html里用的是“”,所以为了避免插入太多的\,php就用print   ' '输出了,这时候该如何解决变量插入字符串的问题呢?

我用printf可以解决,但是总感觉这样很麻烦啊,有没有更简单的办法,就像在“”中插入字符串变量那样简单的办法?

------解决方案--------------------
echo 'your word is {$s} '; --> echo "your word is {$s} ";
单引号中是什么就输出什么。
------解决方案--------------------
如果你非要用单引号
那么就eval或者字符替换
------解决方案--------------------
查一查这个函数吧~~~
eval

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
