今天在网查到一篇介绍php中替换字符串中的空格为逗号','的文章,作个日记保存下来。
复制代码 代码如下:
php <br>/* <br>* 关键词中的空格替换为',' <br>*/ <br>public function emptyreplace($str) { <br>$str = str_replace(' ', ' ', $str); //替换全角空格为半角 <br>$str = str_replace(' ', ' ', $str); //替换连续的空格为一个 <br>$noe = false; //是否遇到不是空格的字符 <br>for ($i=0 ; $i<strlen>if($noe && $str[$i]==' ') $str[$i] = ','; //如果当前这个空格之前出现了不是空格的字符 <br>elseif($str[$i]!=' ') $noe=true; //当前这个字符不是空格,定义下 $noe 变量 <br>} <br>return $str; <br>} <br>?> <br> </strlen>

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.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
