Question

我在一个网站上工作，我想在其中从字符串中提取几个字段。我用来获取该字符串的代码是：

<?php 
   for ($i = 0; $i < count($data['item']->logistic_out); $i++) {
    echo strtolower($data['item']->logistic_out[$i]->logistics_times);

   }
?>

上面的回显代码正在打印以下字符串，logistics_times：

a: 7: {
    s: 3: "mon";a: 2: {
        s: 5: "start";s: 5: "09:00";s: 3: "end";s: 5: "21:00";
    }
    s: 3: "tue";a: 2: {
        s: 5: "start";s: 5: "09:00";s: 3: "end";s: 5: "21:00";
    }
    s: 3: "wed";a: 2: {
        s: 5: "start";s: 5: "09:00";s: 3: "end";s: 5: "21:00";
    }
    s: 3: "thu";a: 2: {
        s: 5: "start";s: 5: "09:00";s: 3: "end";s: 5: "21:00";
    }
    s: 3: "fri";a: 2: {
        s: 5: "start";s: 5: "09:00";s: 3: "end";s: 5: "21:00";
    }
    s: 3: "sat";a: 2: {
        s: 5: "start";s: 5: "09:00";s: 3: "end";s: 5: "21:00";
    }
    s: 3: "sun";a: 2: {
        s: 5: "start";s: 5: "09:00";s: 3: "end";s: 5: "21:00";
    }
}

问题陈述：

我想知道我应该在上面的php代码中进行哪些更改，以便它通过解析以上字符串来提取以下信息：

mon 09:00   21:00
tue 09:00   21:00
wed 09:00   21:00
thu 09:00   21:00
fri 09:00   21:00
sat 09:00   21:00

使用Str_replace（）从字符串中删除空格并使用unserialize（）将数据转换为数组：

    val conf = new SparkConf().setAppName("App10").setMaster("local[*]")
 //   .set("spark.executor.memory", "200g")
      .set("spark.driver.memory", "12g")
      .set("spark.executor.cores", "4")
      .set("spark.driver.cores", "4")
  //  .set("spark.testing.memory", "2147480000")
        .set("spark.sql.shuffle.partitions", "20000")
        .set("spark.driver.maxResultSize", "500g")      
        .set("spark.memory.offHeap.enabled", "true")
        .set("spark.memory.offHeap.size", "200g")
