PHP program to block bad words_PHP tutorial
我们在做留言系统时经常会想把一些不出现的敏感词过滤掉了,下面是一个简单的实现,其实我们可以利用数据库来保存这些信息,然后查出来再作判断即可。
代码如下 | 复制代码 |
/用正则表达式(把脏话想替换成什么就替换成什么) $str = "aa=!!|bb=@@|cc=##|dd=$$|ee=%%|ff=^^|gg=&&"; $arr = explode('|',$str); foreach($arr as $key=>$val) { $array[] = explode('=',$val); } print_r($array); for($i=0;$i $a1[] = "/".$array[$i][0]."/"; $a2[] = $array[$i][1]; } unset($arr); $message= '呵呵 就是一个反社会的时代 WOCAO madE'; echo $message.' '; print preg_replace($a1,$a2,$message); //支持参数个数组 但是参数区分大小写 print eregi_replace($arr1,array('!!','@@','##','$$','%%','^^','&&'),$message); //不支持数组 但是参数 不区分大小写 |

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.
