我有一个foreach语句循环遍历JSON数据并将内容插入MySQL。如果为$ author字符串显示特定的用户名,我想跳过插入。以下方法是正确的还是在数据库级别处理更好?
foreach ($response['data'] as $data) {
$id = $data['id'];
$created_time = $data['created_time'];
$thumbnail = $data['images']['low_resolution']['url'];
$author = $data['user']['username'];
$caption = mysql_real_escape_string($data['caption']['text']);
$link = $data['link'];
$likes = $data['likes']['count'];
if ($author == 'USERNAME') {
mysql_close($con);
} else {
$query = "INSERT IGNORE INTO pbr (id, created_time, thumbnail, author, caption, link, likes, hash) VALUES ('$id', '$created_time', '$thumbnail', '$author', '$caption', '$link', '$likes', '$hash')";
$result = mysql_query($query) or die(mysql_error());
mysql_close($con);
}
}
答案 0 :(得分:3)
为什么在每次循环迭代时关闭SQL连接?
为什么不简单地做:
if ($author == 'USERNAME')
continue; // next iteration
$query = "INSERT IGNORE INTO pbr (id, created_time, thumbnail, author, caption, link, likes, hash)
VALUES ('$id', '$created_time', '$thumbnail', '$author', '$caption', '$link', '$likes', '$hash')";
$result = mysql_query($query) or die(mysql_error());
BTW你应该将参数绑定到你的查询,或者至少使用 mysql_real_escape_string()否则会出现包含引号的值的问题(目前,你只对变量 $ caption ,我猜 $ link , $ thumbnail 和 $ username 也可以包含单引号。
