php转类json格式的数据（没有双引号的JSON格式，一般在硬件对接中出现）

代码如下

= strlen($str)) {return "unexpected end when parsing object key";}$key = substr($str, $pos, $end - $pos);$pos = self::skip_ws($str, $end + 1);if ($pos >= strlen($str)) {return "unexpected end when parsing object key";}if ($str[$pos] == '[') {$res = self::parse_array($str, $pos);$value = $res['arr'];$pos = $res['pos'];} elseif ($str[$pos] == '{') {$res = self::parse_obj($str, $pos);$value = $res['obj'];$pos = $res['pos'];} else {$end = self::parse_str($str, $pos, True, [',', '}']);if ($end >= strlen($str)) {return "unexpected end when parsing object key";}$value = substr($str, $pos, $end - $pos);$pos = $end;}$obj[$key] = $value;$pos = self::skip_ws($str, $pos);if ($pos >= strlen($str)) {return "unexpected end when parsing object key";}if ($str[$pos] == "}") {return ['obj' => $obj, 'pos' => $pos + 1];}}}private static function parse_array($str, $pos){$arr = [];while (True) {$pos = self::skip_ws($str, $pos + 1);if ($pos >= strlen($str)) {return "unexpected end when parsing object key";}if ($pos >= strlen($str)) {return "unexpected end when parsing object key";}if ($str[$pos] == "[") {$res = self::parse_array($str, $pos);$value = $res['arr'];$pos = $res['pos'];} elseif ($str[$pos] == "{") {$res = self::parse_obj($str, $pos);$value = $res['obj'];$pos = $res['pos'];} else {$end = self::parse_str($str, $pos, True, [',', ']']);if ($end >= strlen($str)) {return "unexpected end when parsing object key";}$value = substr($str, $pos, $end - $pos);$pos = $end;}array_push($arr, $value);$pos = self::skip_ws($str, $pos);if ($pos >= strlen($str)) {return "unexpected end when parsing object key";}if ($str[$pos] == "]") {return ['arr' => $arr, 'pos' => $pos + 1];}}}#public static function parse($str) {if(!self::startsWith($str,"json")){return ["error_code"=>1,"msg"=>"请以【json:】开头"];};$pos = strpos($str, ':');if(empty($pos)){return false;}$pos = self::skip_ws($str, $pos+1);if($str[$pos] == '{'){return self::parse_obj($str,$pos)['obj'];}if($str[$pos] == '['){return self::parse_array($str,$pos)['arr'];}}
}

测试：

function test(){$str="json:{name:张三,age:22,book:[{bookname:语文,booksize:200,soce:100},{wkke:123}]}";$str = JsonParser::parse($str);echo json_encode($str);
}
