You should save the gif in a BLOB column.

您应该将gif保存在BLOB列中。

Imagine the following table:

想象一下下表:

CREATE TABLE testblob(
  id INT AUTO_INCREMENT ,
  data MEDIUMBLOB,
  PRIMARY KEY ( id )
) ENGINE = InnoDB;

Then you can use the following INSERT code:

然后您可以使用以下INSERT代码:

<?php
    $dbh = mysql_connect("localhost", "user");
    mysql_select_db("test");
    $data = file_get_contents("your.gif");
    // This is important to avoid a ' to accidentally close a string
    $data = mysql_real_escape_string($data);
    mysql_query("INSERT INTO testblob(data) VALUES ('$data')");
?>

Further you should note, that the mysql_* extension has been marked deprecated. You should use the PDO or mysqli extension instead. I personally prefer PDO. Here comes an example that uses PDO:

此外,您应该注意,mysql_ *扩展已被标记为已弃用。您应该使用PDO或mysqli扩展名。我个人更喜欢PDO。这是一个使用PDO的示例:

$conn = new PDO("mysql:host=$dbhost;dbname=$dbname",$dbuser,$dbpass);

// create a prepared statement
$stmt = $conn->prepare('INSERT INTO `testblob` (`data`) VALUES (:data)');    
// assign the blob value to it
$stmt->bindParam(1, file_get_contents('your.gif'), PDO::PARAM_LOB);

// execute the statemt
$stmt->execute();
