请教一个php数组和字符串的转换问题。我有如下一个字符串：
["approval","bbcode","emoji","english","flags","likes","simplified-chinese"]除了使用explode函数分割处理外，有没有其他的快速将其转换为数组的方法。
$array = json_decode('["approval","bbcode","emoji","english","flags","likes","simplified-chinese"]', true);可以用正则，但效率应该低一些
$str = '"approval","bbcode","emoji","english","flags","likes","simplified-chinese"';
preg_match_all('/\".[^,]*\"/',$str,$out);
print_r($out);
