如何通过添加[在PHP中从Checkbox表单结果中检索？

For example I have code like this: $cities = "resultA, resultB, resultC, resultD, resultE";

Now, I want to retrieve the results to be like this : $finalcities = "[resultA] [resultB] [resultC] [resultD] [resultE]";

Is anybody can help me how to make it as I want? thanks.

to convert the string

$cities = "resultA, resultB, resultC, resultD, resultE";

to

$finalcities = "[resultA] [resultB] [resultC] [resultD] [resultE]";

OPTION A

$finalcities = '['.str_replace(', ','] [',$cities).']';

simple str_repalce of the, comma-space, separator plus the outer []

OPTION B

$finalcities = '['.implode('] [',explode(', ',$cities)).']';

little fancier, first split the string with explode then glue it back together with implode

Just one line of code.

 $cities = '['.str_replace(', ','] [', $cities).']';

We are replacing ', ', with '] [', so it will result in this

resultA][resultB][resultC][resultD][resultE

Now just add '[' and ']' to start and end.

Just add [ and ] bracket from start and end of the string and , will be replaced by ][ string.
