我有一个包含几个方括号的字符串。我需要将值作为数组用方括号分隔。 我的示例将使您理解：
$inputString = "['A'|'AA']['B'|'BB']['C'|'CC']";
我的目标是获得像这样的数组：
0=>'A'|'AA'
1=>'B'|'BB'
2=>'C'|'CC'
答案 0 :(得分：2)

explode答案 1 :(得分：1)
尝试使用PHP爆炸功能。
$inputString = "['A'|'AA']['B'|'BB']['C'|'CC']";
$inputString=str_replace("["," ",$inputString);
print_r (explode("]",rtrim($inputString,"]")));
答案 2 :(得分：0)
尝试一下
$inputString = "['A'|'AA']['B'|'BB']['C'|'CC']";
$obj = str_replace("]","",str_replace("[","",explode("][", $inputString)));
print_r($obj);
答案 3 :(得分：0)
使用preg_match_all
$inputString = "['A'|'AA']['B'|'BB']['C'|'CC']";
preg_match_all('#\[(.*?)\]#', $inputString, $array);
print_r($array[1]);
