当在表mysql中插入php数组的元素时应该是什么样的数据？只有字符串？

Question

我必须将多维php数组的元素插入到表mysql中，但我不知道应该在那里使用什么样的方法。

首先创建表

CREATE TABLE earthquakes (
  milliseconds BIGINT,
  latitude FLOAT,
  longitude FLOAT,
  magnitude FLOAT,
  depth FLOAT,
  source VARCHAR(2),
  region SMALLINT,
  serial VARCHAT(16)
);

我是否应该为其他列添加字符长度？

现在是插入元素的代码：

$array = array(
 array(12345678901112145,-35.4905,167.7843,7.5,450.4,"E",134,"2017-01-10-134"),
 array(12345678901112145,35.4905,-167.7843,3.2,45.4,"U",13,"2016-01-10-14"),
 array(12345678901112145,-35.4905,-167.7843,10.0,4,"I",1,"2016-01-10-1")
);


$data = array();
foreach($array as $row) {
 $milliseconds = mysql_real_escape_string($row[0]);
 $latitude = mysql_real_escape_string($row[1]);
 $longitude = mysql_real_escape_string($row[2]);
 $magnitude = mysql_real_escape_string($row[3]);
 $depth= mysql_real_escape_string($row[4]);
 $source= mysql_real_escape_string($row[5]);
 $code= mysql_real_escape_string($row[6]);
 $serial= mysql_real_escape_string($row[7]); 


 $data[] = "($milliseconds,$latitude,$longitude,$magnitude,$depth,'$source',$code,'$serial')";
}

$values = implode(',', $data);


$sql = "INSERT INTO earthquakes (milliseconds,latitude,longitude,magnitude,depth,source,region,serial) VALUES $values";

我怀疑代码是否正确，但特别是如果我必须为每个元素（添加到表中的每个值）添加 " " 双引号或单引号。

我希望你能帮助我并理解我的英语:(

更新

如果我回显$sql，这是结果

INSERT INTO earthquakes (milliseconds,latitude,longitude,magnitude,depth,source,region,serial) VALUES (12345678901112145,-35.4905,167.7843,7.5,450.4,'E',134,'2017-01-10-134'),(12345678901112145,35.4905,-167.7843,3.2,45.4,'U',13,'2016-01-10-14'),(12345678901112145,-35.4905,-167.7843,10,4,'I',1,'2016-01-10-1')

你应该试试这个：-

 $array = array(
 array(12345678901112145,-35.4905,"222",7.5,450.4,"E",134,"2017-01-10-134"),
 array(12345678901112145,35.4905,-167.7843,3.2,45.4,"U",13,"2016-01-10-14"),
 array(12345678901112145,-35.4905,-167.7843,10.0,4,"I",1,"2016-01-10-1")
);

//----------------------------
 connection to db is necessary to use mysql_real_escape_string function
//----------------------------

$sql = "INSERT INTO earthquakes (milliseconds,latitude,longitude,magnitude,depth,source,region,serial) VALUES ";

foreach($array as $row) {
     $milliseconds = mysql_real_escape_string($row[0]);
     $latitude = mysql_real_escape_string($row[1]);
     $longitude = mysql_real_escape_string($row[2]);
     $magnitude = mysql_real_escape_string($row[3]);
     $depth= mysql_real_escape_string($row[4]);
     $source= mysql_real_escape_string($row[5]);
     $code= mysql_real_escape_string($row[6]);
     $serial= mysql_real_escape_string($row[7]); 
     $sql .="($milliseconds,$latitude,$longitude,$magnitude,$depth,'$source',$code,'$serial'),";
}
$sql = rtrim($sql, ',');
excute the sql here.

如果列类型为 varchar，则必须在值中添加 '' 单冒号。
