javascript - 用] json替换 “[ with [ and ]”

我有一个JSON，如下所示:

[{"type":"Point","coordinates":"[-77.03,38.90]"},"properties":{"city":3,"url":"xyz.com"}]

我想将"[替换为[，将]"替换为]

最佳答案

试试这个

 $yourJson = [{"type":"Point","coordinates":"[-77.03,38.90]"},"properties":{"city":3,"url":"xyz.com"}];
 $jsonString=preg_replace('/"([^"]+)"\s*:\s*/', '$1:', $yourJson);
    $stringReplace=str_replace('"[', '[', $jsonString);
    $stringReplace=str_replace(']"', ']', $stringReplace);
    echo $stringReplace;
