php正则表达式具体的,真头大了。。。
提取以下两行数据
123[test] abc c1 c2 c3
456 def d1[test] d2 d3
以换行和空格为分割
要求提取到
123,abc,c1 c2 c3
456,def,d1 d2 d3
数据中间可能还有[*]要忽略
求preg_match_all匹配表达式
------解决方案--------------------
要preg_match_all还是preg_replace?
那些逗号是怎么回事?后面的三个为何又没有逗号?
------解决方案--------------------
正则,不会。。
- PHP code
$str = '123[test] abc c1 c2 c3 456 def d1[test] d2 d3'; $ar = split("[\n\r]+",$str); $ar1 = explode(' ',$ar[0]); $ar2 = explode(' ',$ar[1]); function fmt($ar) { foreach($ar as $k => $v) $ar[$k] = preg_replace('/\[.*\]/','',$v); return $ar; } $ar1 = fmt($ar1); $ar2 = fmt($ar2); $str = implode(' ',$ar1)."\n".implode(' ',$ar2); echo "<pre class="brush:php;toolbar:false">{$str}"; /* //Output 123 abc c1 c2 c3 456 def d1 d2 d3 */ <br><font color="#e78608">------解决方案--------------------</font><br>
------解决方案--------------------
行多倒不怕,上面代码稍做修改就可以适应不定行数据。

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.
