有没有办法用preg_split替换一些引号并留下一些？

Question

我正在尝试使用preg_split()，但结果并不是我期望从函数中获得的结果。

我是php和整个preg_split()场景的新手，对我来说似乎很难理解，至少在目前。

$row = "EL10,40,2019-02-06,55555,2019-01-06,[email protected],"Text , random text , 52555885/ 48484848484",Yes,One Two,Broke,2019-01-01,000.00,0.00,0.0,0.0,0.0,0.00,0.00,0.0,VRA "Morning";

$row_expl = preg_split('/(?:[^"]*"|)\K\s*(,\s*|$)/',$row);

我希望删除逗号分隔符，同时将逗号留在引号中。

一切似乎都有效，唯一的问题发生在最后。它为：VRA "Morning"添加了额外的引号。结果如下："VRA ""Morning"""

正则表达式实际上是您的问题的错误工具。定义分隔符和机箱字符的CSV解析器是您需要的工具。

str_getcsv('EL10,40,2019-02-06,55555,2019-01-06,[email protected],"Text , random text , 52555885/ 48484848484",Yes,One Two,Broke,2019-01-01,000.00,0.00,0.0,0.0,0.0,0.00,0.00,0.0,VRA "Morning')

str_getcsv的默认分隔符是,，封闭字符是"，所以应该使用默认选项进行设置。你可以在这里看到更多关于这个功能的http://php.net/manual/en/function.str-getcsv.php。
