PHP字符串表示为数组到数组

Question

$var = "['test', 'test2', 'test3']";

how do I create a workable array from this in PHP?

I've tried explode($var, ","); but this didn't seem to work, unless something went wrong with that attempt.

Answer 1

explode($var, ","); is wrong. explode needs the first argument to be the delimiter and the second be the string. Replace [] and then explode -

$var = "['test', 'test2', 'test3']";

$var = str_replace(array('[', ']'), '', $var);
$arr = explode(',', $var);
